Abstract:

Agricultural technological change plays a crucial role in food security and agricultural development. In the case of considering economic risks and technical risk tolerance, farmers will use different technologies to match production factors to achieve the optimal production state. Therefore, under different farmland management modes, farms show different characteristics of technological progress. This paper attempts to compare and analyze agricultural technology development under different farmland management modes: the unified management mode of collective organizations (UMCO) and the decentralized management mode of contracted families (DMCF). The Stochastic Frontier Analysis (SFA) of the translog average production function was applied to the 24 farms of the Hulunbuir Agricultural Reclamation Group, of which 11 farms in the western part of the Greater Khingan Mountains (Western Farms) were managed by the DMCF, and the other 13 farms in the eastern part of the Greater Khingan Mountains (Eastern Farms) were managed by the UMCO. The results are as follows: (1) without considering the resource allocation efficiency, from 2000 to 2019, the generalized technological progress rate (TFPG) of the 13 Eastern Farms (7.65%) was higher than that of the Western Farms (2.25%). (2) The returns to scale (SRC) of the Western Farms was higher than that of the Eastern Farms. (3)The technological efficiency change rate (TEC) and the technical progress (TP) of the Eastern Farms is higher than that of the Western Farms. It is recommended that farms strengthen the construction of their infrastructure and service systems, resist natural disasters, reduce the disaster’s impact on technological progress, give full play to the overall planning advantages of the collective organizations, improve the product allocation efficiency factors, and create connotative profit points.

Abstract:

Past studies have discussed the “socialist” nature of agricultural development in China in terms of equality in distribution since the introduction of the Household Responsibility System (hrs) and its institutional necessities. This article instead addresses the issue of the modernization of the peasant economy by exploring the various practices in agricultural production that led to a socialist path since 1980. The peasant economy under thehrstakes the form of a dual-layer management, and the collective economy is under the unified management by the collective. The collective economy propels the modernization of the peasant economy by the means of integration of funding, integration of land rights, and land concentration, respectively, in response to the different phases in the development of the forces of production. What is emerging in China is the fourth path to agricultural modernization characteristic of China, after the existing three paths, namely capitalist agriculture of large private farms, socialist agriculture of large collective farms, and the capitalist agriculture of small family farms. This new path, or socialist agriculture of small family farms, is characterized by the enlargement of the management unit on the basis of the collective economy that overcomes the constraints of the peasant economy. However, while institutional possibilities do exist for a socialist path in agricultural development in China, the policies pursued by the Chinese government are turning Chinese agriculture into capitalist agriculture of small family farms.学界从均等分配角度揭示了家庭承包经营制后农业发展的“社会主义”性质及其制度合理性，本文尝试从农业生产角度揭示1980年以来中国社会主义道路实践，探究小农经济现代化问题。家庭承包经营制改革后的小农经济采取双层经营体制，集体经济以集体统一经营的方式存在。在不同生产力阶段，集体经济分别以资金整合、地权整合和土地集中的方式，促进小农经济现代化。从集体经济扩大农业经营单位，克服小农经济局限性的角度，中国在资本主式私人大农场农业、社会主义式集体大农场农业、资本主义式小农家庭农业之外，探索出具有中国特色的第四种农业现代化道路，即社会主义式小农家庭农业。中国农业发展有走向社会主义道路的制度空间，但中国政府的政策选择使得中国农业发展正在走向资本主义式小农家庭农业。(This article is in Chinese.)

AbstractHow do dignity discourses shift the framing of struggles for basic legal freedoms? Based on our decade-long empirical research on lawyers and politics in China, we provide a theoretical intervention in a burgeoning socio-legal scholarship on dignity in this article. Drawing inductively from in-depth interviews, we find that a powerful current of dignity consciousness and sentiment, joined by an acute awareness of dignity harms, flows through the community of Chinese activist lawyers. Their dignity discourses can be witnessed and explained in four streams of awareness: (1) dignity experienced as an ideal in juridical, philosophical, and theological idioms; (2) dignity takings experienced indirectly and directly in the property takings of clients’ homes, farms, and livelihood; (3) assaults on dignity through property takings of spaces of religious worship; and (4) the takings of professional dignity from the lawyers charged with defending the dignity of others. This article points to the value of dignity framings in the general theory of collective action for basic legal freedoms.

Abstract:

The rural land rental market is playing an increasingly important role in the agricultural transformation period for developing countries, including China, where rural farmland rental is highly context-specific with the implementation of the collective-owned rural land system; thus, in turn, the access to farmland rental markets for rural households has profoundly influenced their livelihood strategies and income earnings. This paper investigates the income impact differences caused by rural households’ farmland rental participation activities and explores such impact mechanisms by further evaluating the income impacts caused by rental area and household agricultural productivity. Data from the Chinese national household survey were used for estimating the empirical models. Our results show that farmland renting has positively affected households’ on-farm and total income, but there is no significant effect upon off-farm income. According to income differences across quantiles, we find households with high on-farm income are more sensitive about enlarging their farm size by renting farmland, and households with middle and upper-middle off-income may benefit more from renting out their farmland. Furthermore, the joint effects of renting area and household agricultural productivity on lessee households’ farm income is significantly positive. For lessor households, our results indicate that renting out farmland did not improve their off-farm and total income as it may have a limited effect on farm household labor distribution. Our findings suggest that engaging in farmland rental activity can enhance farming productivity efficiency and poverty alleviation among rural households. Under the collective-owned rural land system, it is urgent and necessary to initiate and design incentive policies to encourage highly efficient large farms to expand the farm size and provide smallholders with equal opportunities to engage in farmland rental activities.

This article assesses the economic, legal and environmental conditions that Thai rubber farmers face and evaluates actions they can take to increase incomes.Statistical analyses determine relationships between prices of oil, natural and synthetic rubber. Pearson correlation tests found a strong positive relationship (r = 0.887) between the price of Brent crude and Thai ribbed smoked sheets, and a moderate positive relationship between price changes in Brent and synthetic rubber (r = 0.648). Regression analysis showed Brent oil price is a good predictor of natural rubber price. Moderate to strong positive relationships were also found between natural rubber price and the gross domestic products of Japan, China and the United States. Criminal antitrust behaviour in the rubber industries appeared to interfere with normal pricing in rubber markets. No significant bivariate correlation was found between rainfall in Thailand and natural rubber price, production or export, although fl ooding and other environmental issues clearly affected rubber farms. A survey of options showed that Thai rubber farmers can best improve their livelihoods through the collective purchase and use of new technologies and by integrating into downstream supplychain industries. At the very least, farmers are urged to abandon monocrop methods and supplement their incomes with fruit, fi sh, livestock or pigs.

Abstract:

The article considers topical issues of land reform in Ukraine in the context of the introduction of the Ukrainian model of the agricultural land market (AL). The purpose of the study is a comparative analysis of the official and author's models of the market turnover of ALs in order to increase the strengths and neutralize the weaknesses of the first of them and turn it into an exclusive model, rather than a copy of the worst variants of the baseline models. It is shown that the state model, which is practiced in Israel, China and other countries, is based on lease land relations - between the state, as the owner of the land, and collective agricultural enterprises, and these relations are regulated by the state land authority. It is determined that the farming model, as the most common and effective, has in its basis a private form of ownership of land, which is cultivated mainly by small and medium farms, and lease land relations are complemented by the market. And these relations, as in Poland, are regulated by state and self-governing bodies. It has been established that the latifundist model of the AL market is also based on private ownership of land, but the main market entities are not farms, but agricultural holdings. Within the framework of this model, land relations between the market entities are oriented mainly on land grabbing and are usually regulated by the general competence authorities. In general, this model is the most threatening to the food security of many countries where it is practiced, such as Madagascar, and the sustainable development of their rural areas. It is justified that the Ukrainian model of the AL market from July 21, 2021 to January 1, 2024 will have many signs of a farming model. But since then, it should not become a «hybrid» of the latifundist, but a combined version of the farm and state models. At the same time, the emphasis should be placed not on the privatization of land, but on their effective use, based on the advantages of the lease form of the land circulation, which are associated with the introduction of long-term lease, increasing its price and transferring to the electronic form.

Abstract:

Reasonably promoting the off-farm employment of rural surplus labor in China’s collective forest areas is an important way to increase forest resources and increase farmers’ income. China’s new round of collective forest tenure reform (CFTR) aims to optimize forest area labor allocation by strengthening forestland property rights. Therefore, in different village off-farm environments, it is necessary to explore how forestland property rights affect off-farm employment in forest areas. Based on survey data from 742 households in Zhejiang and Jiangxi provinces, this paper examines this effect using the double-hurdle model. The results indicate that forestland transfer rights promote decision-making about, and the supply of, off-farm labor, while forest harvesting rights significantly increase the supply of off-farm labor. The villages’ off-farm income ratio also affected the supply of off-farm labor. Moreover, under the regulation of the village off-farm income ratio, the positive incentives of forestland transfer rights on decision-making about, and the supply of, off-farm labor gradually weakened, but the incentive effect of forest harvesting rights on the supply of off-farm labor gradually increased. It is proposed that the CFTR should be further promoted, the forestland circulation mechanism and regulating forest harvest quota system should be improved, and implementation of forestry property mortgages should be strengthened.

Abstract:

Swine enteric disease is the predominant cause of morbidity and mortality, and viral species involved in swine enteric disease include rotaviruses and coronaviruses, among others. Awareness of the circulating porcine rotavirus group C (PoRVC) in pig herds is critical to evaluate the potential impact of infection. At present, due to the lack of disease awareness and molecular diagnostic means, the research on RVC infection in China is not well-studied. In this study, diarrhea samples collected from pig farms were detected positive for RVC by PCR, and the full-length RVC was not previously reported for Chinese pig farms. This rotavirus strain was designated as RVC/Pig/CHN/JS02/2018/G6P6. A natural recombination event was observed with breakpoints at nucleotides (nt) 2509 to 2748 of the VP2 gene. Phylogenetic analysis based on nsp1 revealed that a new branch A10 formed. Collectively, our data suggest a potentially novel gene recombination event of RVC in the VP2 gene. These findings provide a new insight into the evolution of the rotavirus.

Abstract:

Collective Forestland Tenure Reform has confirmed the forestland tenure of rural households and made forestland property rights clearer. In order to explain whether this policy is effective in improving rural households’ expected returns and sense of forestland tenure security, we built models to study the impact of off-farm employment on forestland input in the context of labor migration to urban areas. We used data from the rural household tracking survey conducted by the Development Research Center of the National Forestry and Grassland Bureau from 2003–2016, which includes nine provinces (districts) and 1227 sample rural households in China. Regression models with the forestland titling program as the key influencing factor were constructed, controlling for household characteristics, household head characteristics, forestland characteristics, village level characteristics, market characteristics, and policy factors. Forestland leases had no significant on cash outlays and labor inputs. Forest tenure mortgage loans had a significant positive effect on cash outlays and labor inputs. For households’ off-farm employment, the moderating effects of labor migration on labor inputs and cash outlays are modeled separately. The study indicated that the forestland tenure titling certificates increase households’ enthusiasm in forestland production and promote cash outlays and labor inputs in forestland management. The results regarding the moderating effect indicated that labor migration has a positive moderating effect on rural households’ forestland inputs including labor inputs and cash outlays.

AbstractA major institution for the ethnic Han (Chinese) colonisation of Xinjiang is the Production and Construction Corps. Although quasi-military in origin, its military role is now eclipsed by its economic role. Traditionally it was primarily a collection of state farms, but in recent years its industrial enterprises have expanded. It has also played a role in imprisoning convicts from eastern China. Largely destroyed during the Cultural Revolution, it was actually abolished for a few years beginning in 1975. But the perceived need to project Chinese influence into the area, and to protect against ethnic unrest and Soviet pressures, persuaded the authorities that the Corps should be revived. Today the Corps has 2.8 million members, or 14 percent of Xinjiang’s population, and plays a significant role in the region’s economy.

Abstract:

Porcine Circovirus 2 (PCV2) is a crucial swine pathogen and considered a primary causative agent of porcine circovirus-associated diseases (PCVADs), posing a serious economic threat to the swine industry across globe. The world’s biggest agricultural conglomerates have teamed up to create giant commercial pig farms across Shanghai due to the proximity of this region to more affluent lean-pork markets. Since its discovery, PCV2 has displayed extraordinary genetic diversity, and its genome is swiftly evolving through a series of mutations and recombinations. However, limited information on epidemiology, molecular characteristics, vaccine cross-protection, and the co-infection rate of PCV2 with other lethal swine diseases can adversely impact the pig production in the region. To investigate the molecular epidemic characteristics and genetic evolution of PCV2, pigs with doubtful symptoms of PCVADs were sampled from various commercial pig farms with a history of PWMS and/or PDNS across Shanghai from 2014 to 2018. Our results revealed the coexistence of multiple PCV2 genotypes (PCV2b, PCV2e, and PCV2d) among Shanghai pig herds and dominance of PCV2d among them. We also found critical amino acid substitutions in epitope regions of important capsid proteins in PCV2 isolates involved in viral replication and host immune escape. Spotted mutations may favor the prevalence and survival of various PCV2 genotypes despite availability of commercial vaccines. This study also provides insight into the co-infection status of PCV2 with major lethal swine viral diseases such as PPV and PPRSV. Collectively, these investigations will contribute to understanding the molecular epidemiology and evolution of PCV2 across the region.

Abstract:

Porcine reproductive and respiratory syndrome virus (PRRSV) is a significant threat to the pig industry in China. However, the epidemiological characteristics of PRRSV after the outbreak of African swine fever in China were not thoroughly investigated. In the present study, the serological and epidemiological investigations of PRRSV in pigs from the Hunan and Hebei provinces of China were assessed. The results showed that 73.12% (95% CI 71.74–74.49) of pigs were positive for PRRSV-special antibody by enzyme-linked immunosorbent assay. Out of 5799 samples, 482 (8.31%, 95% CI 7.60–9.02) samples were positive for PRRSV nucleic acids. The positive rates of PRRSV in healthy pigs from farms and slaughterhouses were 2.27% (47/2072) and 7.70% (217/2818), which were lower than that in diseased pigs (23.98%, 218/909). Furthermore, the full-length OFR5 gene sequences of 43 PRRSV strains were sequenced and analysed. Phylogenetic analysis revealed that 43 isolates were classified into three lineages, namely lineage 1 (n = 24), lineage 8 (n = 15), and lineage 3 (n = 4). Lineage 1 could be further divided into sublineage 1.5 (n = 2) and sublineage 1.8 (n = 22), and lineage 8 was classified into sublineage 8.1 (n = 3) and sublineage 8.7 (n = 12). Collectively, our findings revealed the severe prevalence of PRRSV in the Hunan and Hebei provinces, where sublineage 1.8 and sublineage 8.7 predominated. The present study provides the update information of the epidemiological and genetic characteristics of PRRSV in the investigated regions, which will be beneficial for PRRS control.

ABSTRACTStreptococcus suis, a global zoonosis of pigs, shows regional differences in the prevalence of human-associated disease for Asian and non-Asian countries. The isolation rates and diversities ofS. suison tonsils of healthy slaughter pigs in China and the United Kingdom were studied for effects of geography, temperature, pig age, and farm type. Isolates underwent analysis of molecular serotype and multilocus sequence type and virulence-associated genotyping. Although we found no significant difference in positive isolation rates between Chinese and UK farms, the prevalences of serotypes previously associated with human disease were significantly greater in the Chinese collection (P= 0.003). A significant effect of temperature was found on the positive isolation rate of the Chinese samples and the prevalence of human disease-associated serotypes in the UKS. suispopulation (China,P= 0.004; United Kingdom,P= 0.024) and on the prevalence of isolates carrying key virulence genes in China (P= 0.044). Finally, we found marked diversity amongS. suisisolates, with statistically significant temperature effects on detection of multiple strain types within individual pigs. This study highlighted the high carriage prevalence and diversity ofS. suisamong clinically healthy pig herds of China and the United Kingdom. The significant effect of temperature on prevalence of isolation, human disease-associated serotypes, and diversity carried by individual pigs may shed new light on geographic variations in humanS. suis-associated disease.IMPORTANCEStreptococcus suisis a global zoonotic pathogen and also a normal colonizer mainly carried on the tonsil of pigs. Thus, it is important to study the effect of environmental and management-associated factors on theS. suispopulations in clinically healthy pigs.

Abstract:

Mink refractory diarrhea is a seasonal disease that occurs in many mink farms in China. Mink circovirus (MiCV) has been recognized as the causative agent of the disease. The aim of the study was to develop a subunit vaccine against mink refractory diarrhea. A recombinant baculovirus strain expressing the capsid protein was constructed using the baculovirus expression vector system (BEVS). A subunit vaccine was developed based on the capsid protein with appropriate adjuvant. Then, a field trial was carried out in two districts in order to evaluate the efficiency of the subunit vaccine. The field trial indicated that in total, only 1.8% of the minks developed typical diarrhea in the vaccinated group compared with 74.5% in the control group. The vaccination could significantly reduce the infection rate of MiCV among the mink herds and could restrain the virus’ shedding from feces. Furthermore, the vaccinated group had a higher average litter size in the following year compared to the control group. Collectively, the results indicated that the subunit vaccine based on the capsid protein can provide reliable protection against MiCV infection.

Abstract:

Cotton, as an important cash crop and strategic material, is widely planted in Xinjiang, China. In the traditional way, the management of the cotton field is extensive and the cost is huge. This paper analyzed the economic benefits and the related influence factors of cotton field management digitalization by collecting costs from 2020 of four major tasks in field management in Xinjiang, China. These four main tasks included field scouting, plant protection, topping and irrigation. By analyzing the intersection of the average cost curves of each major task in field management, we obtained the critical size of digital agriculture replacing traditional agriculture. Then, we used sensitivity analysis to find the main factors affecting the promotion and application of digital agricultural equipment. The results show: (1) at a certain critical size, the use of digital agricultural equipment can reduce the cost of production compared to traditional agriculture. However, the critical size varies for different management segments. (2) Fixed equipment costs, labor costs, water costs and energy costs have a large impact on the critical size. On large-scale cotton farms, digital agriculture tends to be more economical than traditional agriculture. In the future, as the cost of fixed equipment decreases, and labor costs and water costs rise, the critical size of digital agriculture replacing traditional agriculture will get smaller, and the scope of the economic benefits of digital cotton field management will increase further.

Abstract:

In the context of food security, the market-oriented allocation of factors under the collective ownership system has had a profound impact on agricultural production. As a hot issue under the Household Responsibility System (HRS), the impact mechanism of farmland market transaction on agricultural production efficiency deserves discussion. Based on the stochastic frontier production function model, this paper analyzes the impact of farmland transfer on farmers’ production technical efficiency under the external environmental factors by using the moderating effect and threshold effect. The study found that farmland transfer can improve farmers’ technical efficiency. The market price of agricultural products and farmland transfer subsidies have a positive moderating effect on the impact of farmland transfer on technical efficiency. Furthermore, farmland transfer subsidy shows a nonlinear effect on the impact of technical efficiency.

Abstract:

This document seeks to present the instrument known as the DIAMOND OF INNOVATION and its “green version”, reveals the genesis from the results shown with the generation of the collection of books called: ASIAN FIRMS. Using these eight books makes it possible to discover the business model of the central countries (PR China, Republic of India) and Southeast Asia (Japan, South Korea, R. China-Taiwan, Singapore, Vietnam), focusing on continuous Innovation. This process, which tested and perfected the instrument, is accompanied by companies from the industrial and Colombian primary sectors. The tool shows its ability to establish a diagnosis in a city, country, company in terms of Innovation and establish a strategy based on the eight points of the Diamond and accompany it with a hierarchy or strategic priority. To this end, the use of secondary tools is established, such as the STRATEGIC MOTHER MATRIX. It detects the behavior of the leading countries for each of the Diamond points, becoming “good practices”, and determines the backwardness or practices to improve, prioritizing each strategy to be developed, seeking to advance on the subject of Innovation. With the advancement of research, sponsored from the beginning by the Universidad Piloto de Colombia and its Business Administration program and research partners such as Grupo SASA and some farms in the Ubaté valley (Department of Cundinamarca), dedicated to the main production focused on In dairy, the “green” version of the Innovation Diamond is tested and launched, its reason for being: to prevent Innovation in a country, city, company, from being accepted simply for being Innovation, without considering its impact in the environment.

Abstract:

Brucellosis is an important zoonosis occurring globally. In addition to the risk for disease in humans, the disease causes production losses, since the disease in livestock is characterized by abortion and other reproductive failures. The disease is a public health concern in China, but no information is available on knowledge, perception and awareness of potential risk groups such as farmers, butchers and animal health workers; yet successful control requires compliance of those affected groups to be effective. Following the principles of the Ecohealth approach, emphasis was given to participation of all relevant stakeholders, use of qualitative and quantitative tools, and cross-sectorial collaboration. Data collection included on-farm questionnaires (N = 192) and collection of bulk milk samples of goat (N = 40), cattle (N = 45) and buffalo (N = 41) from farms, as well as serum samples (N = 228) from humans. Milk samples were tested with an ELISA for presence of antibodies, while a serum agglutination test was used for human samples. Qualitative work included 17 focus group discussion (FGD) with villagers and 47 in-depth interviews (IDI) with village animal health workers, doctors, and butchers, focused on knowledge, perception and awareness on zoonoses including brucellosis. Results from questionnaires indicate that abortions are a common problem; cattle with abortion history are kept for further insemination and the milk still consumed or sold. Antibodies against Brucella were detected in cows’ (5/45) and goats’ (1/40) milk samples, and in human samples (5/126) in Yiliang, while in Mangshi, all buffalo (N = 41) and humans (N = 102) were negative. FGD and IDI results showed an alarmingly low knowledge and awareness on zoonoses; particularly, low awareness about brucellosis was noted, even among the professional groups. Collaboration between village animal health workers and doctors was uncommon. No confirmed brucellosis cases were found in retrospective investigation of hospital and veterinary stations. This study demonstrates the presence of brucellosis in livestock and humans in Yunnan, indicating a non-negligible risk for humans. It is also made apparent that there is a need for increased awareness among both farmers and professionals in order to reduce the risk of zoonotic transmissions.

Abstract:

Raw milk microbiota is complex and influenced by many factors that facilitate the introduction of undesirable microorganisms. Milk microbiota is closely related to the safety and quality of dairy products, and it is therefore critical to characterize the variation in the microbial composition of raw milk. In this cross-sectional study, the variation in raw milk microbiota throughout the year (n = 142) from three farms in China was analyzed using 16S rRNA amplicon sequencing, including α and β diversity, microbial composition, and the relationship between microbiota and milk quality parameters. This aimed to characterize the contamination risk of raw milk throughout the year and the changes in quality parameters caused by contamination. Collection month had a significant effect on microbial composition; microbial diversity was higher in raw milk collected in May and June, while milk collected in October and December had the lowest microbial diversity. Microbiota composition differed significantly between milk collected in January–June, July–August, and September–December (p < 0.05). Bacterial communities represented in raw milk at the phylum level mainly included Proteobacteria, Firmicutes and Bacteroidota; Pseudomonas, Acinetobacter, Streptococcus and Lactobacillus were the most common genera. Redundancy analysis (RDA) found strong correlations between microbial distribution and titratable acidity (TA), fat, and protein. Many genera were significantly correlated with TA, for example Acinetobacter (R = 0.426), Enhydrobacter (R = 0.309), Chryseobacterium (R = 0.352), Lactobacillus (R = −0.326), norank_o__DTU014 (R = −0.697), norank_f__SC-I-84 (R = −0.678), and Subgroup_10 (R = −0.721). Additionally, norank_f__ Muribaculaceae was moderately negatively correlated with fat (R = −0.476) and protein (R = −0.513). These findings provide new information on the ecology of raw milk microbiota at the farm level and contribute to the understanding of the variation in raw milk microbiota in China.

Full text

Abstract:

Multifunctional agriculture (MFA) has attracted increased attention from academics and policymakers in recent years. Academic researchers have utilised various approaches to assess and measure the multifunctionality of agriculture and rural landscapes. This paper outlines the nature of MFA and key supporting policies, before reviewing the applied research approaches, drawing primarily from the European Union and China where specific policies on MFA have been implemented to support rural development and promote sustainable rural communities. Four distinct types of valuation of modern MFA are recognised: economic, biophysical, socio-cultural, and holistic. Following a search of both the recent and older MFA literature, evaluations of the strengths and weaknesses of quantitative, qualitative, and mixed methods applications are provided using examples from a range of recent studies. The review illustrates the diversity of approaches to measure MFA. While noting that many studies operate at a landscape scale, the challenge remains that the lack of commonality in the research approaches applied means it is difficult to provide effective comparisons between studies or to compare findings. A future research agenda will need to emphasise the need for more consideration of the roles of MFA research to support decision-makers, especially policy makers, but also farmers who largely make decisions for individual farms but, if considered collectively, can transform production systems at a landscape scale.

Abstract:

Understanding passengers’ responses to fare changes is the basis to design reasonable price policies. This work aims to explore retiming responses of travelers changing departure times due to a prepeak discount pricing strategy in the Beijing subway in China, using smart card records from an automatic fare collection (AFC) system. First, a new set of classification indicators is established to segment passengers through a two-step clustering approach. Then, the potentially influenced passengers for the fare policy are identified, and the shifted passengers who changed their departure time are detected by tracing changes in passengers’ expected departure times before and after the policy. Lastly, the fare elasticity of departure time is defined to measure the retiming responses of passengers. Two scenarios are studied of one month (short term) and six months (middle term) after the policy. The retiming elasticity of different passenger groups, retiming elasticity over time, and retiming elasticity functions of shifted time are measured. The results show that there are considerable differences in the retiming elasticities of different passenger groups; low-frequency passengers are more sensitive to discount fares than high-frequency passengers. The retiming elasticity decreases greatly with increasing shifted time, and 30 minutes is almost the maximum acceptable shifted time for passengers. Moreover, the retiming elasticity of passengers in the middle term is approximately twice that in the short term. Applications of fare optimization are also executed, and the results suggest that optimizing the valid time window of the discount fares is a feasible way to improve the congestion relief effect of the policy, while policy makers should be cautious to change fare structures and increase discounts.

Abstract:

The aim of the study was to investigate knowledge and use of wild food plants and fungi in Han (i.e. Chinese) nationality villages in central China, including famine plants used in the respondents' childhood. A valley adjacent to the extremely species-rich temperate forest vegetation of the Taibai Nature Reserve was chosen. Eighty-two people from 5 villages took part in the study. Altogether, 159 wild food plant species and 13 fungi folk taxa were mentioned by informants. The mean number of freelisted wild foods was very high (24.8; median – 21.5). An average respondent listed many species of wild vegetables (mean – 17, me- dian – 14.5), a few wild fruits (mean – 5.9 and median – 6) and very few fungi (mean – 1.9, median – 1), which they had eaten. Over 50% of respondents mentioned gathering the young shoots or leaves of Celastrus orbiculatus, Staphylea bumalda and S. holocapra, Caryopteris divaricata, Helwingia japonica, Pteridium aquilinum, Pimpinella sp., Amaranthus spp., Matteucia struthiopteris, Allium spp., Cardamine macrophylla and Chenopodium album. Only one species of fruits (Schisandra sphenanthera) and none of the mushrooms were mentioned by over half of the respondents. Although very diverse, it can be noted that the use of wild vegetables has decreased compared to the second half of the 20th century, as informants listed several plants which they had stopped using (e.g. Abelia engleriana) due to the availability of cultivated vegetables and other foodstuffs. On the other hand, the collection of the most well-known wild vegetables is maintained by selling them to tourists visiting agritourist farms, and restaurants.

Abstract:

Porcine reproductive disorders have been considered as the major factors that threaten pig industries worldwide. In this study, 407 aborted-fetus samples were obtained from 89 pig farms in Hunan province, to investigate the prevalence of four viruses associated with porcine reproductive disease, including porcine reproductive and respiratory syndrome virus (PRRSV), porcine circovirus type 2 (PCV2), pseudorabies virus (PRV), and classical swine fever virus (CSFV). Meanwhile, the target gene sequences of representative PRRSV (ORF5), PCV2 (ORF2), CSFV (E2), and PRV (gE) strains were amplified, sequenced, and analyzed. The results showed that the positive rates of PRRSV, PCV2, PRV, and CSFV among the collected samples were 26.29% (107/407), 52.83% (215/407), 6.39% (26/407), and 12.29% (50/407), respectively. Moreover, co-infection with two and three pathogens were frequently identified, with PCV2/PRRSV, PRRSV/CSFV, PRRSV/PRV, PCV2/CSFV, PCV2/PRV, and PRRSV/PCV2/CSFV mix infection rates of 9.09%, 3.19%, 2.95%, 3.69%, 2.21%, and 0.49%, respectively. Moreover, ORF5-based phylogenetic analysis showed that 9, 4, and 24 of 37 PRRSV strains belonged to the PRRSV2 lineages 1, 5, and 8, respectively. ORF2-based phylogenetic analysis revealed that PCV2d and PCV2b were prevalent in Hunan province, with the proportions of 87.5% (21/24) and 12.5% (3/24), respectively. An E2-based phylogenetic tree showed that all 13 CSFV strains were clustered with 2.1 subgenotypes, these isolates were composed of 2.1b (10/13) and 2.1c (3/13) sub-subgenotypes. A gE-based phylogenetic tree showed that all six PRV strains belonged to the genotype II, which were genetically closer to variant PRV strains. Collectively, the present study provides the latest information on the epidemiology and genotype diversity of four viruses in sows with reproductive diseases in Hunan province, China, which would contribute to developing effective strategies for disease control.

Abstract:

Explicit spatial information about crop types on smallholder farms is important for the development of local precision agriculture. However, due to highly fragmented and heterogeneous cropland landscapes, fine-scale mapping of smallholder crops, based on low- and medium-resolution satellite images and relying on a single machine learning (ML) classifier, generally fails to achieve satisfactory performance. This paper develops an ensemble ML-based framework to improve the accuracy of parcel-level smallholder crop mapping from very high spatial resolution (VHSR) images. A typical smallholder agricultural area in central China covered by WorldView-2 images is selected to demonstrate our approach. This approach involves the task of distinguishing eight crop-level agricultural land use types. To this end, six widely used individual ML classifiers are evaluated. We further improved their performance by independently implementing bagging and stacking ensemble learning (EL) techniques. The results show that the bagging models improved the performance of unstable classifiers, but these improvements are limited. In contrast, the stacking models perform better, and the Stacking #2 model (overall accuracy = 83.91%, kappa = 0.812), which integrates the three best-performing individual classifiers, performs the best of all of the built models and improves the classwise accuracy of almost all of the land use types. Since classification performance can be significantly improved without adding costly data collection, stacking-ensemble mapping approaches are valuable for the spatial management of complex agricultural areas. We also demonstrate that using geometric and textural features extracted from VHSR images can improve the accuracy of parcel-level smallholder crop mapping. The proposed framework shows the great potential of combining EL technology with VHSR imagery for accurate mapping of smallholder crops, which could facilitate the development of parcel-level crop identification systems in countries dominated by smallholder agriculture.

Abstract:

The Bali Government has made the implementation of the electric vehicle (EV) policy a high priority considering its attractiveness for emission and air pollution reduction to maintain the sustainability of Bali’s nature and tourism sector. Considering the uniqueness of the tourism sector in Bali and the mobility it generates, this study aims to investigate the factors that influence EV use by tourists based on several scenarios for estimating EV share target and the emission reduction contributed. For those purposes, the stated choice questionnaire was distributed online and offline to tourists in Bali and analyzed using the multinomial logit (MNL) model. While the study done during pandemic times, where the number of the tourist is significantly decreasing and the travel behavior influenced by mobility restriction imposed by the government, the data collection still covered mobility of both international and domestic tourist. The survey found that rental cost and accessibility, as well as the quality of charging stations are factors that affect EV use by tourists. Motorcycle parking cost was also found to influence EV use. These findings align with previous studies, and interventions such as fiscal incentives for rental companies and infrastructure development are suggested similar to EV incentives implemented in China, India, or the US. The development of the low emission zone (LEZ) is also proposed to manage parking fares similar to what was implemented in London, specifically to push the shift from internal combustion engine (ICE) to EV. Based on emission inventory calculation, 1.9 million kg of potential annual CO2 can be prevented with the implementation of these policies by the government.

Abstract:

Donkeys (Equus asinus) face a global crisis. The health, welfare, and even survival of donkeys are being compromised as the demand for their skins increases. It is driven by the production of ejiao, a traditional Chinese remedy believed by some to have medicinal properties. It is estimated that the ejiao industry currently requires approximately 4.8 million donkey skins per year. Since there is no productive chain for donkey skin production outside of China, the activity is extractive and has resulted in the decimation of donkeys. Gestation is 12 months in donkeys, increasing the risk of extinction if such practices are not controlled. In this scenario, the donkeys are collected (purchased for low prices, stolen, and collected from the side of the roads) and are then often transported for long distances, usually without water, food, or rest. The trade, in Brazil, poses significant biosecurity risks, particularly because examinations are rarely conducted and therefore infectious diseases, such as glanders and infectious anemia, remain undetected. Furthermore, in chronic stress situations, the immune system is suppressed, increasing the biosecurity risk, especially because donkeys are a silent carrier of diseases. Rarely there is traceability with animals from different origins being put together in “fake farms”, before being delivered to slaughterhouses. The opportunistic strategy of collecting animals, or buying for low prices, keeping them without access to food and veterinary assistance, is what makes this trade profitable. Our experience in donkey welfare and the global skin trade suggest that it will be enormously challenging and cost-prohibitive to run a trade at the standards required to be considered humane, sustainable, and safe. Although donkeys are being blamed for the involvement in road accidents, it is not an ethical solution to maintain this trade as an alternative. Moreover, the ecological role of donkeys in native ecosystems has not been elucidated, and some studies indicate they could even have a positive effect. Regardless of the future the donkeys will have; we must guarantee a life with the least dignity to the animals under our responsibility.

Abstract:

The article analyzes the support for the US market, where the government has allocated almost $ 22.2 billion for the development of dairy cattle. direct and indirect subsidies to the country's dairy sector (35.02 c/l), which is equivalent to 73% of farmers' milk sales, showed relatively high domestic support, export subsidies, conservation programs, risk management programs, disaster relief programs, loan programs, crop insurance, livestock support. Surveys to support the Indian market, which ranks second in the world in raw milk production (9.5%), have shown that almost 80% of small-scale farmers are small-scale farmers. Milk collection is carried out by 130 thousand dairy cooperatives. NABARD (National Bank for Agriculture and Rural Development) under DEDS, provides for subsidies of up to 25% of costs. China is investing heavily in the construction of large dairy farms and livestock complexes with up to 100,000 cows. The Australian market produces 9.3 million tonnes of milk, of which 36% is exported and is the world's fourth exporter of dairy products (6% of the world market). Australia's dairy cattle are characterized by a small amount of direct government support. During 2015-2016, agriculture received financial and commercial assistance over $ 147 million. US in the form of payments to farms. It has been established that price forecasting plays an important role in regulating the milk market in Australia, on the basis of which the profile Ministry, taking into account world prices, generates milk price indices. Analysis of milk production in Switzerland has shown that it remains highly subsidized. In 2013, state support for milk producers amounted to CHF 1.8 billion, incl. direct subsidies are estimated at 1.5 billion Swiss francs, which is 61 thousand Swiss francs per dairy farm, or 0.41 Swiss francs per 1 liter of milk. The state support system for dairy cattle in Canada has been found to include the following instruments: import tariffs that restrict dairy imports; minimum guaranteed prices for raw milk that are set at the maximum amount of milk sold to the dairies within the quota; a system of direct payments to farmers for milk production within the quota. The amount of direct payments per 1 liter of milk is set annually by the government. In order to support Canadian producers in technological modernization aimed at improving the efficiency of milk production, a dairy farm investment program (DFIP) is implemented with state support of $ 250 million. USA According to the Organization for Economic Co-operation and Development (OECD) in Iceland, Japan, Norway and Switzerland, the level of support for dairy producers exceeds on average 70% of the gross income of farmers, in Canada, the EU, Hungary, Korea and the USA the amount of support is 40-55%. An analysis of the support for the development of dairy cattle in the EU countries showed that the following instruments are allocated for these purposes: production restrictions (milk production quotas); government interventions and storage; Establishment of product sales regulations / regulations; the dairy package (including regulating contractual relations in the dairy sector); foreign trade (import regulations, export subsidies); government subsidies. It is found that the main factor that increases the profitability of dairy production in developed countries is the improvement of quality and differentiation of the range. Major factors contributing to the successful development of dairy cattle are increased government support and economical use of resources. Also used are a set of financial incentives, including reducing the tax burden. Key words: Livestock, milk market, domestic support, development programs, cooperation, financial incentives, subsidies, import tariffs, quotas.

Abstract:

Garlic chives, Allium tuberosum Roth., are widely cultivated in Asia and are the fourth most important Allium crop in Korea. In June 2011, a leaf blight of garlic chives associated with a Septoria spp. was observed on an organic farm in Hongcheon County, Korea. Similar symptoms were also found in fields within Samcheok City and Yangku County of Korea during the 2011 and 2012 seasons. Disease incidence (percentage of plants affected) was 5 to 10% in organic farms surveyed. Diseased voucher specimens (n = 5) were deposited at the Korea University Herbarium (KUS). The disease first appeared as yellowish specks on leaves, expanding to cause a leaf tip dieback. Half of the leaves may be diseased within a week, especially during wet weather. Pycnidia were directly observed in leaf lesions. Pycnidia were amphigenous, but mostly epigenous, scattered, dark brown to rusty brown, globose, embedded in host tissue or partly erumpent, separate, unilocular, 50 to 150 μm in diameter, with ostioles of 20 to 40 μm in diameter. Conidia were acicular, straight to sub-straight, truncate at the base, obtuse at the apex, hyaline, aguttulate, 22 to 44 × 1.8 to 3 μm, mostly 3-septate, occasionally 1- or 2-septate. These morphological characteristics matched those of Septoria allii Moesz, which is differentiated from S. alliacea on conidial dimensions (50 to 60 μm long) (1,2). A monoconidial isolate was cultured on potato dextrose agar (PDA). Two isolates have been deposited in the Korean Agricultural Culture Collection (Accession Nos. KACC46119 and 46688). Genomic DNA was extracted using the DNeasy Plant Mini DNA Extraction Kit (Qiagen Inc., Valencia, CA). The internal transcribed spacer (ITS) region of rDNA was amplified using the ITS1/ITS4 primers and sequenced. The resulting sequence of 482-bp was deposited in GenBank (JX531648 and JX531649). ITS sequence information was at least 99% similar to those of many Septoria species, however no information was available for S. allii. Pathogenicity was tested by spraying leaves of three potted young plants with a conidial suspension (2 × 105 conidia/ml), which was harvested from a 4-week-old culture on PDA. Control leaves were sprayed with sterile water. The plants were placed in humid chambers (relative humidity 100%) for the first 48 h. After 7 days, typical leaf blight symptoms started to develop on the leaves of inoculated plants. S. allii was reisolated from the lesions of inoculated plants, confirming Koch's postulates. No symptoms were observed on control plants. The host-parasite association of A. tuberosum and S. allii has been known only from China (1). S. alliacea has been recorded on several species of Allium, e.g. A. cepa, A. chinense, A. fistulosum, and A. tuberosum from Japan (4) and A. cepa from Korea (3). To the best of our knowledge, this is the first report of S. allii on garlic chives. No diseased plants were observed in commercial fields of garlic chives which involved regular application of fungicides. The disease therefore seems to be limited to organic garlic chive production.

Abstract:

India has created as the fastest developing major economy on earth and is depended upon to be extraordinary compared to other three economic forces of the world all through the accompanying 10-15 years, upheld by its strong vote based framework and affiliations. The economy of India is depicted as a creating market economy. It is the world’s fifth-greatest economy by apparent GDP and the third-greatest by Purchasing Power Equality (PPP). Since the start of the 21st century, yearly typical GDP development has been 6% to 7%, and from 2014 to 2018, India was the speediest developing major economy, beating China. Unquestionably India was one of the greatest economies on earth for most of the two centuries from first until nineteenth century. The long stretchdevelopment perspective of the Indian economy remains positive in light of its young people and contrasting low dependence extent, sound save reserves and investment rates, and is growing fuse into the worldwide economy. The economy moved in 2017, due to paralyzes of “demonetization” in 2016 and introduction of Goods and Services Tax in 2017. Practically 60% of India’s GDP is driven by domestic private utilization and keeps on lingering the world’s sixth greatest purchaser market. Beside private utilization, India’s GDP is moreover filled by government spending, investment and trades. In 2018, India was the world’s 10th greatest merchant and the nineteenth-greatest exporter. India has been a person from World Trade Organization since 1 January 1995. It situated 63rd on Ease of working together rundown and 68th on Global Competitiveness Report. With 510-million-authorities, the Indian work power is the world’s second-greatest beginning at 2018.During the 2008 worldwide monetary crisis the economy went up against smooth log jam, India attempted improvement measures to help development and produce demand; in resulting year’s economic development re-established. As shown by World Bank, to achieve down to earth economic development India must focus on open sector change, establishment, horticultural and provincial development, departure of land and work rules, budgetary joining, prod private investment and fares, instruction and public prosperity. Hence, the present study has been conducted with an aim to give an overview on the International Market scenario in the modern economic era and study based on secondary sources of data collection.

Abstract:

AbstractThelohanellus kitauei is a spore-forming myxosporean parasite prevalent in scattered mirror carp (Cyprinus carpio) that generates numerous cysts in the intestine and causes mass mortality in fish. To investigate the infection and mortality induced by T. kitauei in pond-reared farms in Luo-Jiang (104°51’N, 31°31’E), southwest China, morphological and molecular analyses of infected fish were conducted. Natural and specific immune indicators were further evaluated to determine the immunological effects of response to parasitic infection. The infectious parasite was identified as Thelohanellus kitauei based on morphological, 18S rDNA and infectious characteristics. Scattered mirror carp was determined as the specific intermediate host of the parasite. However, T. kitauei still caused considerable damage to the fish, in particular, injury and blockage of the intestines, resulting in malnutrition and even death. The mature spores of T. kitauei colonize the intestinal submucosa of carp and form cysts of various sizes that block the intestinal tract and release spores into the enteric cavity upon rupture, leading to the next phase of T. kitauei growth. Moreover, T. kitauei-infected carp showed weaker innate immunity. IgM is involved in the fight against parasitic infection while cytokines, such as IL-6, IL-1β and TNF-α, had an impact on infection processes. To our knowledge, this is the first report to show that T. kitauei infects and causes death in scattered mirror carp. Our collective findings from systematic pathology, morphology and immunology experiments provide a foundation for further research on infections by this type of parasite and development of effective treatment strategies.

Meatification describes a momentous dietary transformation: the average person on earth today consumes nearly twice as much animal flesh every year as did the average person just two generations ago, amidst a period of rapid human population growth and with marked disparities between rich and poor. Further, meatification is projected to continue in the coming three decades, at the same time as the world adds another 2 billion people, with growth concentrated in fast-industrializing countries. There is overwhelming evidence that meatification bears heavily on a range of problems including climate change, biodiversity loss, food consumption disparities, mounting risks of antibiotic resistance, increasing rates of non-communicable disease, and growing realms of animal suffering. The basic implication is inescapable: the de-meatification of diets is an urgent environmental and social priority, and must be part of any project of providing critical food guidance. There are many signs this recognition is growing in environmental and public health advocacy (including pressure to reform dietary guidelines, most notably in China), calls for a ‘meat tax’, and in rising levels of vegetarianism and veganism in some of the countries that have long been at the forefront of meatification. After briefly summarizing the course of meatification and the de-meatification imperative, this chapter focuses on its 3 primary possibilities: conscientious omnivory (which has various hues, as in calls for ‘green’ or ‘ethical’ meat); vegetarianism; and veganism. The first possibility, conscientious omnivory, recognizes the need to reduce 'meatification' from levels of consumption in industrialized countries, but resolutely upholds the need for some livestock products in human diets and for small livestock populations in mixed farming systems, due to their role recycling some wastes, returning condensed nutrients to land, and providing some labour. From this perspective, necessity makes some meat consumption (but less than in industrialized countries today) a 'benign indulgence' in Simon Fairlee’s terms, with the challenge to source meat, eggs, and milk from sustainable mixed farms where the animals have lived decent lives. The second possibility, vegetarianism, accepts the functional necessity of small livestock populations in mixed farming systems, which includes their ability to generate useable nutrition along with providing beneficial on-farm services (augmented, for some, by pure palate pleasure, as in the love of ice cream, cheesy pizza, or scrambled eggs), but seeks a non-violent resolution. But unlike conscientious omnivory, the need for animals on mixed farms does not justify killing them for food, much less make it ‘benign’, and it is seen to be desirable and possible for animals to have good lives with only reproductive outputs (i.e. milk and unfertilized eggs) and wool taken, rather than flesh. The third possibility, veganism, rejects all use of animals in production and consumption, arguing that the place of livestock in mixed farming systems for most of agrarian history does not justify its continuance in the present age. This position holds that livestock production is an inherently inefficient way of meeting human nutritional needs for two basic reasons: first, there is compelling evidence that it is not only possible to be healthy with plant-based diets but that they often lead to improved health and lower risks of non-communicable diseases; and second, it is clear that plant-based diets tend to command much less land and resources, on average, than do either omnivorous or vegetarian diets. Along with improving population health, meeting human nutritional needs more efficiently is seen to have the potential to enhance distributional equity. Finally, the case for veganism insists that vegetarianism cannot escape some level of systematic killing of animals, as most males are not productive in this conception and because females become unproductive short of their natural lifespan. In spite of key mutual objections to the current scale of animal consumption and industrial production, there are often heated debates between conscientious omnivores, vegetarians, and vegans. Observing this, some might assume that these groups should just aim to get along, submerge their differences, and focus collective energies on confronting the big, urgent need to build momentum for de-meatification and undermine industrial livestock production. In such a few, debates about the end point of de-meatification appear as unnecessary distractions, to the extent that these groups discredit one another, and are best left (or at least strategically moderated) for that future day when industrial livestock production is eradicated. This paper suggests that thinking critically about different end-points is necessary to recognize the challenges of alliance-building and constructively communicating the de-meatification imperative.

Abstract:

During World War II, the Soviet Union’s food supply was in a state of crisis. Hitler’s army had occupied the agricultural heartlands of Ukraine and Southern Russia in 1941 and, as a result, agricultural production for the entire nation had plummeted. Soldiers in Red Army, who easily ate the best rations in the country, subsisted on a daily allowance of just under a kilogram of bread, supplemented with meat, tea, sugar and butter when and if these items were available. The hunger of the Red Army and its effect on the morale and strength of Europe’s eastern warfront were causes for concern for the Soviet government and its European and American allies. The one country with a food surplus decided to do something to help, and in 1942 the United States agreed to send thousands of pounds of meat, cheese and butter overseas to help feed the Red Army. After receiving several shipments of the all-American spiced canned meat SPAM, the Red Army’s quartermaster put in a request for a more familiar canned pork product, Russian tushonka. Pound for pound, America sent more pigs overseas than soldiers during World War II, in part because pork was in oversupply in the America of the early 1940s. Shipping meat to hungry soldiers and civilians in war torn countries was a practical way to build business for the U.S. meat industry, which had been in decline throughout the 1930s. As per a Soviet-supplied recipe, the first cans of Lend-Lease tushonka were made in the heart of the American Midwest, at meatpacking plants in Iowa and Ohio (Stettinus 6-7). Government contracts in the meat packing industry helped fuel economic recovery, and meatpackers were in a position to take special request orders like the one for tushonka that came through the lines. Unlike SPAM, which was something of a novelty item during the war, tushonka was a food with a past. The original recipe was based on a recipe for preserved meat that had been a traditional product of the Ural Mountains, preserved in jars with salt and fat rather than by pressure and heat. Thus tushonka was requested—and was mass-produced—not simply as a convenience but also as a traditional and familiar food—a taste of home cooking that soldiers could carry with them into the field. Nikita Khrushchev later claimed that the arrival of tushonka was instrumental in helping the Red Army push back against the Nazi invasion (178). Unlike SPAM and other wartime rations, tushonka did not fade away after the war. Instead, it was distributed to the Soviet civilian population, appearing in charity donations and on the shelves of state shops. Often it was the only meat product available on a regular basis. Salty, fatty, and slightly grey-toned, tushonka was an unlikely hero of the postwar-era, but during this period tushonka rose from obscurity to become an emblem of socialist modernity. Because it was shelf stable and could be made from a variety of different cuts of meat, it proved an ideal product for the socialist production lines where supplies and the pace of production were infinitely variable. Unusual in a socialist system of supply, this product shaped production and distribution lines, and even influenced the layout of meatpacking factories and the genetic stocks of the animals that were to be eaten. Tushonka’s initial ubiquity in the postwar Soviet Union had little to do with the USSR’s own hog industry. Pig populations as well as their processing facilities had been decimated in the war, and pigs that did survive the Axis invasion had been evacuated East with human populations. Instead, the early presence of tushonka in the pig-scarce postwar Soviet Union had everything to do with Harry Truman’s unexpected September 1945 decision to end all “economically useful” Lend-Lease shipments to the Soviet Union (Martel). By the end of September, canned meat was practically the only product still being shipped as part of Lend-Lease (NARA RG 59). Although the United Nations was supposed to distribute these supplies to needy civilians free of cost, travelers to the Soviet Union in 1946 spotted cans of American tushonka for sale in state shops (Skeoch 231). After American tushonka “donations” disappeared from store shelves, the Soviet Union’s meat syndicates decided to continue producing the product. Between its first appearance during the war in 1943, and the 1957 announcement by Nikita Khrushchev that Soviet policy would restructure all state animal farms to support the mass production of one or several processed meat products, tushonka helped to drive the evolution of the Soviet Union’s meat packing industry. Its popularity with both planners and the public gave it the power to reach into food commodity chains. It is this backward reach and the longer-term impacts of these policies that make tushonka an unusual byproduct of the Cold War era. State planners loved tushonka: it was cheap to make, the logistics of preparing it were not complicated, it was easy to transport, and most importantly, it served as tangible evidence that the state was accomplishing a long-standing goal to get more meat to its citizenry and improving the diet of the average Soviet worker. Tushonka became a highly visible product in the Soviet Union’s much vaunted push to establish a modern food regime intended to rival that of the United States. Because it was shelf-stable, wartime tushonka had served as a practical food for soldiers, but after the war tushonka became an ideal food for workers who had neither the time nor the space to prepare a home-cooked meal with fresh meat. The Soviet state started to produce its own tushonka because it was such an excellent fit for the needs and abilities of the Soviet state—consumer demand was rarely considered by planners in this era. Not only did tushonka fit the look and taste of a modern processed meat product (that is, it was standard in texture and flavor from can to can, and was an obviously industrially processed product), it was also an excellent way to make the most of the predominant kind of meat the Soviet Union had the in the 1950s: small scraps low-grade pork and beef, trimmings leftover from butchering practices that focused on harvesting as much animal fat, rather than muscle, from the carcass in question. Just like tushonka, pork sausages and frozen pelmeny, a meat-filled pasta dumpling, also became winning postwar foods thanks to a happy synergy of increased animal production, better butchering and new food processing machines. As postwar pigs recovered their populations, the Soviet processed meat industry followed suit. One official source listed twenty-six different kinds of meat products being issued in 1964, although not all of these were pork (Danilov). An instructional manual distributed by the meat and milk syndicate demonstrated how meat shops should wrap and display sausages, and listed 24 different kinds of sausages that all needed a special style of tying up. Because of packaging shortages, the string that bound the sausage was wrapped in a different way for every type of sausage, and shop assistants were expected to be able to identify sausages based on the pattern of their binding. Pelmeny were produced at every meat factory that processed pork. These were “made from start to finish in a special, automated machine, human hands do not touch them. Which makes them a higher quality and better (prevoskhodnogo) product” (Book of Healthy and Delicious Food). These were foods that became possible to produce economically because of a co-occurring increase in pigs, the new standardized practice of equipping meatpacking plants with large-capacity grinders, and freezers or coolers and the enforcement of a system of grading meat. As the state began to rebuild Soviet agriculture from its near-collapse during the war, the Soviet Union looked to the United States for inspiration. Surprisingly, Soviet planners found some of the United States’ more outdated techniques to be quite valuable for new Soviet hog operations. The most striking of these was the adoption of competing phenotypes in the Soviet hog industry. Most major swine varieties had been developed and described in the 19th century in Germany and Great Britain. Breeds had a tendency to split into two phenotypically distinct groups, and in early 20th Century American pig farms, there was strong disagreement as to which style of pig was better suited to industrial conditions of production. Some pigs were “hot-blooded” (in other words, fast maturing and prolific reproducers) while others were a slower “big type” pig (a self-explanatory descriptor). Breeds rarely excelled at both traits and it was a matter of opinion whether speed or size was the most desirable trait to augment. The over-emphasis of either set of qualities damaged survival rates. At their largest, big type pigs resembled small hippopotamuses, and sows were so corpulent they unwittingly crushed their tiny piglets. But the sleeker hot-blooded pigs had a similarly lethal relationship with their young. Sows often produced litters of upwards of a dozen piglets and the stress of tending such a large brood led overwhelmed sows to devour their own offspring (Long). American pig breeders had been forced to navigate between these two undesirable extremes, but by the 1930s, big type pigs were fading in popularity mainly because butter and newly developed plant oils were replacing lard as the cooking fat of preference in American kitchens. The remarkable propensity of the big type to pack on pounds of extra fat was more of a liability than a benefit in this period, as the price that lard and salt pork plummeted in this decade. By the time U.S. meat packers were shipping cans of tushonka to their Soviet allies across the seas, US hog operations had already developed a strong preference for hot-blooded breeds and research had shifted to building and maintaining lean muscle on these swiftly maturing animals. When Soviet industrial planners hoping to learn how to make more tushonka entered the scene however, their interpretation of american efficiency was hardly predictable: scientifically nourished big type pigs may have been advantageous to the United States at midcentury, but the Soviet Union’s farms and hungry citizens had a very different list of needs and wants. At midcentury, Soviet pigs were still handicapped by old-fashioned variables such as cold weather, long winters, poor farm organisation and impoverished feed regimens. The look of the average Soviet hog operation was hardly industrial. In 1955 the typical Soviet pig was petite, shaggy, and slow to reproduce. In the absence of robust dairy or vegetable oil industries, Soviet pigs had always been valued for their fat rather than their meat, and tushonka had been a byproduct of an industry focused mainly on supplying the country with fat and lard. Until the mid 1950s, the most valuable pig on many Soviet state and collective farms was the nondescript but very rotund “lard and bacon” pig, an inefficient eater that could take upwards of two years to reach full maturity. In searching for a way to serve up more tushonka, Soviet planners became aware that their entire industry needed to be revamped. When the Soviet Union looked to the United States, planners were inspired by the earlier competition between hot-blooded and big type pigs, which Soviet planners thought, ambitiously, they could combine into one splendid pig. The Soviet Union imported new pigs from Poland, Lithuania, East Germany and Denmark, trying valiantly to create hybrid pigs that would exhibit both hot blood and big type. Soviet planners were especially interested in inspiring the Poland-China, an especially rotund specimen, to speed up its life cycle during them mid 1950s. Hybrdizing and cross breeding a Soviet super-pig, no matter how closely laid out on paper, was probably always a socialist pipe dream. However, when the Soviets decided to try to outbreed American hog breeders, they created an infrastructure for pigs and pig breeding that had a dramatic positive impact of hog populations across the country, and the 1950s were marked by a large increase in the number of pigs in the Soviet union, as well as dramatic increases in the numbers of purebred and scientific hybrids the country developed, all in the name of tushonka. It was not just the genetic stock that received a makeover in the postwar drive to can more tushonka; a revolution in the barnyard also took place and in less than 10 years, pigs were living in new housing stock and eating new feed sources. The most obvious postwar change was in farm layout and the use of building space. In the early 1950s, many collective farms had been consolidated. In 1940 there were a quarter of a million kolkhozii, by 1951 fewer than half that many remained (NARA RG166). Farm consolidation movements most often combined two, three or four collective farms into one economic unit, thus scaling up the average size and productivity of each collective farm and simplifying their administration. While there were originally ambitious plans to re-center farms around new “agro-city” bases with new, modern farm buildings, these projects were ultimately abandoned. Instead, existing buildings were repurposed and the several clusters of farm buildings that had once been the heart of separate villages acquired different uses. For animals this meant new barns and new daily routines. Barns were redesigned and compartmentalized around ideas of gender and age segregation—weaned baby pigs in one area, farrowing sows in another—as well as maximising growth and health. Pigs spent less outside time and more time at the trough. Pigs that were wanted for different purposes (breeding, meat and lard) were kept in different areas, isolated from each other to minimize the spread of disease as well as improve the efficiency of production. Much like postwar housing for humans, the new and improved pig barn was a crowded and often chaotic place where the electricity, heat and water functioned only sporadically. New barns were supposed to be mechanised. In some places, mechanisation had helped speed things along, but as one American official viewing a new mechanised pig farm in 1955 noted, “it did not appear to be a highly efficient organisation. The mechanised or automated operations, such as the preparation of hog feed, were eclipsed by the amount of hand labor which both preceded and followed the mechanised portion” (NARA RG166 1961). The American official estimated that by mechanizing, Soviet farms had actually increased the amount of human labor needed for farming operations. The other major environmental change took place away from the barnyard, in new crops the Soviet Union began to grow for fodder. The heart and soul of this project was establishing field corn as a major new fodder crop. Originally intended as a feed for cows that would replace hay, corn quickly became the feed of choice for raising pigs. After a visit by a United States delegation to Iowa and other U.S. farms over the summer of 1955, corn became the centerpiece of Khrushchev’s efforts to raise meat and milk productivity. These efforts were what earned Khrushchev his nickname of kukuruznik, or “corn fanatic.” Since so little of the Soviet Union looks or feels much like the plains and hills of Iowa, adopting corn might seem quixotic, but raising corn was a potentially practical move for a cold country. Unlike the other major fodder crops of turnips and potatoes, corn could be harvested early, while still green but already possessing a high level of protein. Corn provided a “gap month” of green feed during July and August, when grazing animals had eaten the first spring green growth but these same plants had not recovered their biomass. What corn remained in the fields in late summer was harvested and made into silage, and corn made the best silage that had been historically available in the Soviet Union. The high protein content of even silage made from green mass and unripe corn ears prevented them from losing weight in the winter. Thus the desire to put more meat on Soviet tables—a desire first prompted by American food donations of surplus pork from Iowa farmers adapting to agro-industrial reordering in their own country—pushed back into the commodity supply network of the Soviet Union. World War II rations that were well adapted to the uncertainty and poor infrastructure not just of war but also of peacetime were a source of inspiration for Soviet planners striving to improve the diets of citizens. To do this, they purchased and bred more and better animals, inventing breeds and paying attention, for the first time, to the efficiency and speed with which these animals were ready to become meat. Reinventing Soviet pigs pushed even back farther, and inspired agricultural economists and state planners to embrace new farm organizational structures. Pigs meant for the tushonka can spent more time inside eating, and led their lives in a rigid compartmentalization that mimicked emerging trends in human urban society. Beyond the barnyard, a new concern with feed-to weight conversions led agriculturalists to seek new crops; crops like corn that were costly to grow but were a perfect food for a pig destined for a tushonka tin. Thus in Soviet industrialization, pigs evolved. No longer simply recyclers of human waste, socialist pigs were consumers in their own right, their newly crafted genetic compositions demanded ever more technical feed sources in order to maximize their own productivity. Food is transformative, and in this case study the prosaic substance of canned meat proved to be unusually transformative for the history of the Soviet Union. In its early history it kept soldiers alive long enough to win an important war, later the requirements for its manufacture re-prioritized muscle tissue over fat tissue in the disassembly of carcasses. This transformative influence reached backwards into the supply lines and farms of the Soviet Union, revolutionizing the scale and goals of farming and meat packing for the Soviet food industry, as well as the relationship between the pig and the consumer.

Abstract:

Abstract Salmonella enterica serovar 1,4,[5],12:i:- (S. 1,4,[5],12:i:-) has been recognized as an emerging foodborne pathogen in recent years. It can cause human salmonellosis predominated by the contamination of animal-derived foods such as raw poultry and pork. This study aimed to characterize the genetic diversity, plasmid replicon types, and antibiotic resistance of 15 S. 1,4,[5],12:i:- environmental isolates collected from two poultry farms using pulsed-field gel electrophoresis (PFGE), multilocus sequence typing (MLST), polymerase chain reaction-based replicon typing, and minimum inhibitory concentration approach. Ten different PFGE genotypes were detected, indicating a high diversity among these S. 1,4,[5],12:i:- isolates. Three sequence types (ST19, ST1544, ST34) were identified by MLST. Among them, ST1544 was first detected in S. 1,4,[5],12:i:- environmental isolates from poultry farms. All isolates were resistant to cefazolin, cefotetan, tobramycin, amikacin, and gentamicin, but susceptible to piperacillin-tazobactam, aztreonam, ceftazidime, cefepime, and ertapenem. Five incompatibility groups (Inc) of plasmids were identified, including IncFIIs (66.7%), IncHI2 (20%), IncI1 (6.7%), IncN (6.7%), and IncQ (6.7%). Among these, 80% of isolates carried at least one plasmid replicon type, and 20% of isolates carried multiple plasmid replicon types. Interestingly, the multidrug-resistant isolate 263 carried numerous resistance genes (i.e., qnrS, aac(6’)-Ib-cr, blaTEM, blaCTX-M-9, blaOXA-1, sul1, sul2, sul3, floR, and mcr-1) and class I integronase gene intI1, which possessed both IncHI2 and IncQ plasmids, suggesting that resistance genes may be horizontally transferred by the combination of IncHI2 and IncQ plasmids. Collectively, antibiotic-resistant S.1,4,[5],12:i:- isolates were first found in poultry farm environments in China, and its surveillance should be strengthened to prevent its further spread from poultry farms to foods.

Abstract:

Pseudorabies (PR), caused by variant pseudorabies virus (PRV), is an economically important viral disease in China. Recently, PRV infection in humans has also received attention worldwide. To investigate the PRV infection in Hunan province, China, we collected a total of 18,138 serum specimens from 808 PRV-vaccinated pig farms cross this region during 2016–2020, and we detected the presence of PRV glycoprotein B (gB) and gE-specific antibodies. The enzyme-linked immunosorbent assay (ELISA) results revealed that 80.47% (14,596/18,138, 95 CI 79.9–81.0) and 23.55% (4,271/18,138, 95 CI 22.9–24.2) of serum samples were positive for PRV gB and gE-specific antibodies, respectively. Further analysis indicated that the seroprevalence of wild PRV infection was associated with the season and breeding scale (p < 0.01). In addition, five PRV strains were isolated from PRV-positive samples in Vero cells and the virus titers varied from 106.5 to 107.51 TCID50/0.1 ml. The phylogenetic analysis revealed that one isolate was a classical strain of PRV genotype II, and four other isolates belonged to the variants of genotype II. Collectively, the data indicate that the prevalence of PRV remains high in pigs in Hunan province, and the variant PRV strains are the major genotypes affecting the development of the pig industry.

Abstract:

Despite the discovery of several closely related viruses in bats, the direct evolutionary progenitor of SARS-CoV-2 has not yet been identified. In this study, we investigated potential animal sources of SARS-related coronaviruses using archived specimens from Sunda pangolins (Manis javanica) and Chinese pangolins (Manis pentadactyla) confiscated from the illegal wildlife trade, and from common palm civets (Paradoxurus hermaphroditus) raised on wildlife farms in Viet Nam. A total of 696 pangolin and civet specimens were screened for the presence of viral RNA from five zoonotic viral families and from Sarbecoviruses using primers specifically designed for pangolin coronaviruses. We also performed a curated data collection of media reports of wildlife confiscation events involving pangolins in Viet Nam between January 2016 and December 2020, to illustrate the global pangolin supply chain in the context of Viet Nam where the trade confiscated pangolins were sampled for this study. All specimens from pangolins and civets sampled along the wildlife supply chains between February 2017 and July 2018, in Viet Nam and tested with conventional PCR assays designed to detect flavivirus, paramyxovirus, filovirus, coronavirus, and orthomyxovirus RNA were negative. Civet samples were also negative for Sarbecoviruses, but 12 specimens from seven live pangolins confiscated in Hung Yen province, northern Viet Nam, in 2018 were positive for Sarbecoviruses. Our phylogenetic trees based on two fragments of the RdRp gene revealed that the Sarbecoviruses identified in these pangolins were closely related to pangolin coronaviruses detected in pangolins confiscated from the illegal wildlife trade in Yunnan and Guangxi provinces, China. Our curated data collection of media reports of wildlife confiscation events involving pangolins in Viet Nam between January 2016 and December 2020, reflected what is known about pangolin trafficking globally. Pangolins confiscated in Viet Nam were largely in transit, moving toward downstream consumers in China. Confiscations included pangolin scales sourced originally from Africa (and African species of pangolins), or pangolin carcasses and live pangolins native to Southeast Asia (predominately the Sunda pangolin) sourced from neighboring range countries and moving through Viet Nam toward provinces bordering China.

Abstract:

AbstractAccurate solar and wind generation forecasting along with high renewable energy penetration in power grids throughout the world are crucial to the days-ahead power scheduling of energy systems. It is difficult to precisely forecast on-site power generation due to the intermittency and fluctuation characteristics of solar and wind energy. Solar and wind generation data from on-site sources are beneficial for the development of data-driven forecasting models. In this paper, an open dataset consisting of data collected from on-site renewable energy stations, including six wind farms and eight solar stations in China, is provided. Over two years (2019–2020), power generation and weather-related data were collected at 15-minute intervals. The dataset was used in the Renewable Energy Generation Forecasting Competition hosted by the Chinese State Grid in 2021. The process of data collection, data processing, and potential applications are described. The use of this dataset is promising for the development of data-driven forecasting models for renewable energy generation and the optimization of electricity demand response (DR) programs for the power grid.

Abstract:

Shiga toxin-producing Escherichia coli (STEC) is an important food-borne pathogen, which can cause diseases such as diarrhea, hemorrhagic enteritis, and hemolytic uremic syndrome in humans. Twelve STEC isolates were collected from beeves and feces of commercial animals in China between 2019 and 2020 for this study. In addition to the determination of serotype and Shiga toxin subtype, whole-genome sequencing (WGS) was used for determining phylogenetic relationships, antimicrobial resistance (AMR), virulence genes, and sequence type (ST) of isolates. A total of 27 AMR genes were detected, and each STEC isolate carried more than 10 AMR genes. Eight STEC isolates from ground beef and four STEC isolated from feces were screened. A total of seven serotypes were identified, and one isolate ONT:H10 was undetermined by SeroTypeFinder. Three O157:H7 strains were confirmed and the remaining five serogroups were confirmed as O26:H11, O81:H31, O105:H8, O178:H19, and O136:H12. The phylogenetic analysis showed that STEC isolates of the same serotype or ST were clustered together based on cgMLST. The comparison of the genomes of 157 STEC reference isolates worldwide with our local STEC isolates showed that STEC isolates screened in China represented various collections and could not form a separate cluster but were interspersed among the STEC reference collection, which suggested that several STEC isolates shared a common ancestor irrespective of STEC serotype isolates. cgMLST revealed that isolates of the same O serotype clustered irrespective of their H type. Further investigation is required to determine the pathogenic potential of other serotypes of STEC, particularly in regard to these rare serotypes.

Abstract:

Salmonella enterica is a widespread foodborne pathogen with concerning antimicrobial resistance (AMR). Waterfowl are a major source of Salmonella transmission, but there are few systematic studies on Salmonella prevalence in waterfowl species. In this study, 126 Salmonella isolates (65 collected in 2018–2020 and 61 collected in 2002–2005) were obtained from waterfowl samples in Sichuan, China. Their serotypes, pulsed-field gel electrophoresis (PFGE) types, and phenotypic and genotypic AMR profiles were systematically examined. The isolates were distributed in 7 serotypes, including serovars Enteritidis (46.0%), Potsdam (27.8%), Montevideo (7.9%), Cerro (6.3%), Typhimurium (4.8%), Kottbus (4.0%) and Apeyeme (3.2%). Their PFGE characteristics were diverse; all isolates were distributed in four groups (cutoff value: 60.0%) and 20 clusters (cutoff value: 80.0%). Moreover, all isolates were multidrug resistant, and high rates of AMR to lincomycin (100.0%), rifampicin (100.0%), sulfadiazine (93.7%), erythromycin (89.7%), ciprofloxacin (81.0%), and gentamicin (75.4%) were observed. Finally, 49 isolates were subjected to whole-genome sequencing, and a wide variety of AMR genes were found, including multiple efflux pump genes and specific resistance genes. Interestingly, the tet(A)/tet(B) and catII resistance genes were detected in only isolates obtained in the first collection period, while the gyrA (S83F, D87N and D87G) and gyrB (E466D) mutations were detected at higher frequencies in the isolates obtained in the second collection period, supporting the findings that isolates from different periods exhibited different patterns of resistance to tetracycline, chloramphenicol and nalidixic acid. In addition, various incompatible plasmid replicon fragments were detected, including Col440I, Col440II, IncFIB, IncFII, IncX1, IncX9, IncI1-I and IncI2, which may contribute to the horizontal transmission of AMR genes and provide competitive advantages. In summary, we demonstrated that the Salmonella isolates prevalent in Sichuan waterfowl farms exhibited diverse serotypes, multiple AMR phenotypes and genotypes, and AMR changes over time, indicating their potential risks to public health.

Abstract:

Astragalus sinicus L., (Chinese milk vetch) is a traditional leguminous green manure that plays a significant role in maintaining paddy soil fertility to enhance yield and the quality of rice in China. It is also found in gardens, roadsides, farms, fields, riverbanks, open wastelands, and is often used as livestock feed. From February 2019 to 2021, severe powdery mildew infections were observed on hundreds of A. sinicus grown in gardens and at roadsides of Fuzhou city, China. The disease incidence was up to 100% on leaves and stems of A. sinicus. White superficial fungal colonies (circular to irregular patches) were present on both sides of the leaves. Hyphae were flexuous to straight, branched, 4 to 8 µm in width, and septate. Hyphal appressoria were lobulate and solitary or in opposite pairs. Conidiophores were erect and straight, hyaline, and 60 to 120 × 8 to 10 µm (n=30). Foot cell was cylindrical, straight to slightly curved, 22 to 38 × 8 to 10 µm, followed by two to three shorter cells. Conidia were cylindrical-oval to doliiform, 30 to 48 × 13.5 to 24 μm with a length/width ratio of 1.6 to 2.4 (n = 30), formed singly, and without fibrosin bodies. Conidial germ tubes were produced subterminal position. No chasmothecia were found in the collected samples. The morphological characteristics of asexual structures were consistent with the descriptions of E. trifoliorum (Wallr.) U. Braun in Braun and Cook (2012). To verify the identification of the pathogen, the ITS and the part of large subunit (LSU) rDNA gene of the isolates were amplified using ITS1/ITS4 and LSU1/ LSU2 primers (Scholin et al. 1994 and White et al. 1990, respectively) and sequences were deposited in GenBank (ITS: MZ021332, MZ021333; LSU: MZ021334, MZ021335). In BLASTn searches, the ITS and LSU sequences were 99 to 100% identical with those of E. trifoliorum parasitic on Lathyrus magellanicus (LC010015), Medicago littoralis (LC270860), Melilotus officinalis (LC009924) and Trifolium spp., (MN216308, KY660821), as well as E. baeumleri (Bradshaw et al. 2021) on Vicia nigricans (LC010014). Pathogenicity test was performed by gently pressing a diseased leaf onto 10 young leaves of three healthy potted plants, while three non-inoculated plants were used as controls. All plants were maintained in a greenhouse at 20 to 25°C, without humidity control, and natural light. Symptoms developed 7 days after inoculation, whereas the control leaves remained symptomless. The morphology of the fungus on the inoculated leaves was identical to that observed on the originally diseased leaves. Powdery mildew on A. sinicus has been reported as E. pisi and E. polygoni from Korea and China (Shin, 2000; Tai 1979), respectively. Amano (1986) listed E. pisi and Microsphaera astragali (now E. astragali) on A. sinicus from China and Japan. To our knowledge, this is the first report of powdery mildew caused by E. trifoliorum on A. sinicus in China and in general. E. astragali is the most common and widespread powdery mildew species on Astragalus spp. (Braun and Cook 2012) and would be expected on A. sinicus, but this species is genetically clearly different from E. trifoliorum (Bradshaw et al. 2021). The E. trifoliorum complex (clade) is composed of several morphologically well-distinguishable species, besides E. trifoliorum also including E. baeumleri (on Vicia spp.), E. hyperici (on Hypericum spp.), and E. euonymi (on Euonymus spp.), but based on a combination of sequence plus host identity, the collection on A. sinicus can be assigned to E. trifoliorum (Bradshaw et al. 2021). The information in this study extended the host range of E. trifoliorum as well as future studies on A. sinicus in relation to powdery mildew outbreaks in China. References: Amano (Hirata), K. 1986.

Abstract:

Microsatellite markers are now been widely used for the detection and description of micropopulation processes occurring in the populations of domestic animals for the effects of various factors of breeding pressure. Microsatellite loci distributed throughout eukaryotic genomes, making them the preferred genetic marker for high resolution genetic mapping. In recent years, rapid advances have been made in the development of molecular genetic maps. High-density linkage maps are now available for many farm animals, such as cattle, pigs, and goats. In contrast, mapping studies in avian species are much less advanced except in the chicken. According to FAO about 70% of ducks are bred in China. This country is a leader in growing ducks. The Shaoxing breed is one of the three major duck breeds in China. Ducks of this breed are characterized by high performance. According to the Bureau of Product Quality, the age of maturity (the beginning of egg laying) in these birds occurs at 130–140 days. The characteristics of the Shaoxing breed include the fact that the peak period of laying eggs lasts from eight to ten months. On average, one duck in 500 days gives from 290 to 310 eggs, which is one of the highest rates for egg breeds. That is why the purpose of our study was the microsatellite analysis of two populations of Shaoxing breed with 9 locuses was conducted. The selection of birds for the study were carried out on a duck farms in Zhejiang Generation Biological Science and Technology Co., Ltd. and Zhuji Guowei Poultry Development Co, Ltd., and at the laboratory of the Jjejiang Academy of Sciences Institute. Samples collection and DNA preparation: Venous blood samples were collected from 480 ducks (240 ducks of population I and 240 ducks of population II of the Shaoxing breeds) of both populations into 3 ml tubes containing EDTA as anticoagulant agent. In total of 9 investigated loci in the Shaoxing breed population, only one locus was monomorphic (SMO10). The number of different alleles (Na) for each polymorphic locus ranged from 2 (SMO12) to 13 (APL79, CMO11) in population I and from 2 (APL78, SMO12) to 7 (APL79) in population II. On average, one locus had 5.889 alleles in population I and 3.889 of alleles in the population II. The effective number of alleles (Nе) was 1.735 in population I and 1.599 in population II. The number of alleles and the expected heterozygosity (Hexp) values can provide important information for the discrimination of individuals and breeds. The index of expected heterozygosity in population I was 0.336 and 0.307 in population II. The information index (I) was 0,702 in population I and 0,576 in population II. For each population was found private alleles, in population I 6 alleles and in population II just 4 alleles. The results show high level of polymorphism of the studied populations of ducks. The obtained results can be used in the creation of new lines of ducks.

Voropaeva,Viktoriay A. Kolomytseva, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00042 Abstract: This study was aimed at examining the influence of succession cropping on the economic efficiency of no-till field crop rotations on the black earth in the zone of unstable moistening of the Stavropol krai. A long-term stationary experiment was conducted to examine for the purpose nine field crop rotation patterns different in the number of fields (four to six), set of crops, and their succession in crop rotation. The respective shares of legumes, oilseeds, and cereals in the cropping pattern were 17 to 33, 17 to 40, and 50 to 67 %. It has been established that in case of no-till field crop cultivation the economic efficiency of plant production depends on the set of crops and their succession in rotation. The most economically efficient type of crop rotation is the soya-winter wheat-peas-winter wheat-sunflower-corn six-field rotation with two fields of legumes: in this rotation 1 ha of crop rotation area yields 3 850 grain units per ha at a grain unit prime cost of 5.46 roubles; the plant production output return and profitability were 20,888 roubles per ha and 113 %, respectively. The high production profitabilities provided by the soya-winter wheat-sunflower four-field and the soya-winter-wheat-sunflower-corn-winter wheat five-field crop rotation are 108.7 and 106.2 %, respectively. The inclusion of winter wheat in crop rotation for two years in a row reduces the second winter wheat crop yield by 80 to 100 %, which means a certain reduction in the grain unit harvesting rate to 3.48-3.57 thousands per ha of rotation area and cuts the production profitability down to 84.4-92.3 %. This is why, no-till cropping should not include winter wheat for a second time Keywords: No-till technology,crop rotation,predecessor,yield,return,profitability, Refference: I Badakhova G.

View | Download DEVELOPMENT AND TESTING OF AUTONOMOUS PORTABLE SEISMOMETER DESIGNED FOR USE AT ULTRALOW TEMPERATURES IN ARCTIC ENVIRONMENT Authors: Mikhail A. Abaturov,Yuriy V. Sirotinskiy, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00043 Abstract: This paper is concerned with solving one of the issues of the general problem of designing geophysical equipment for the natural climatic environment of the Arctic. The relevance of the topic has to do with an increased global interest in this region. The paper is aimed at considering the basic principles of developing and the procedure of testing seismic instruments for use at ultralow climatic temperatures. In this paper the indicated issue is considered through the example of a seismic module designed for petroleum and gas exploration by passive seismoacoustic methods. The seismic module is a direct-burial portable unit of around 5 kg in weight, designed to continuously measure and record microseismic triaxial orthogonal (ZNE) noise in a range from 0.1 to 45 Hz during several days in autonomous mode. The functional chart of designing the seismic module was considered, and concrete conclusions were made for choosing the necessary components to meet the ultralow-temperature operational requirements. The conclusions made served for developing appropriate seismic module. In this case, the components and tools used included a SAFT MP 176065 xc low-temperature lithium cell, industrial-spec electronic component parts, a Zhaofeng Geophysical ZF-4.5 Chinese primary electrodynamic seismic sensor, housing seal parts made of frost-resistant silicone materials, and finely dispersed silica gel used as water-retaining sorbent to avoid condensation in the housing. The paper also describes a procedure of low-temperature collation tests at the lab using a New Brunswick Scientific freezing plant. The test results proved the operability of the developed equipment at ultralow temperatures down to -55°C. In addition, tests were conducted at low microseismic noises in the actual Arctic environment. The possibility to detect signals in a range from 1 to 10 Hz at the level close to the NLNM limit (the Peterson model) has been confirmed, which allows monitoring and exploring petroleum and gas deposits by passive methods. As revealed by this study, the suggested approaches are efficient in developing high-precision mobile seismic instruments for use at ultralow climatic temperatures. The solution of the considered instrumentation and methodical issues is of great practical significance as a constituent of the generic problem of Arctic exploration.

View | Download COMPARATIVE ANALYSIS OF RESULTS OF TREATMENT OF PATIENTS WITH FOOT PATHOLOGY WHO UNDERWENT WEIL OPEN OSTEOTOMY BY CLASSICAL METHOD AND WITHOUT STEOSYNTHESIS Authors: Yuriy V. Lartsev,Dmitrii A. Rasputin,Sergey D. Zuev-Ratnikov,Pavel V.Ryzhov,Dmitry S. Kudashev,Anton A. Bogdanov, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00044 Abstract: The article considers the problem of surgical correction of the second metatarsal bone length. The article analyzes the results of treatment of patients with excess length of the second metatarsal bones that underwent osteotomy with and without osteosynthesis. The results of treatment of patients who underwent metatarsal shortening due to classical Weil-osteotomy with and without osteosynthesis were analyzed. The first group consisted of 34 patients. They underwent classical Weil osteotomy. The second group included 44 patients in whomosteotomy of the second metatarsal bone were not by the screw. When studying the results of the treatment in the immediate postoperative period, weeks 6, 12, slightly better results were observed in patients of the first group, while one year after surgical treatment the results in both groups were comparable. One year after surgical treatment, there were 2.9% (1 patient) of unsatisfactory results in the first group and 4.5% (2 patients) in the second group. Considering the comparability of the results of treatment in remote postoperative period, the choice of concrete method remains with the operating surgeon.

Methods. A prospective 3-year study of 86 healthy dogs (aged 1-7 yrs) of different breeds and of both sexes. Echo homogeneity and echogenicity of the stomach and intestines wall were determined by the method of Silina, T.L., et al. (2010) in absolute values of average brightness levels of ultrasound image pixels using the 8-bit scale with 256 shades of gray. Results. Quantitative echogenicity indicators of the stomach and the small intestine wall in dogs were determined. Based on the numerical values characterizing echogenicity distribution in each layer of a separate structure of the digestive system, the coefficient of gastric echogenicity is determined as 1:2.4:1.1 (mucosa/submucosa/muscle layers, respectively), the coefficient of duodenum and jejunum echogenicity is determined as 1:3.5:2 and that of ileum is 1:1.8:1. Clinical significance. The echogenicity coefficient of the wall of the digestive system allows an objective assessment of the stomach and intestines wall and can serve as the basis for a quantitative assessment of echogenicity changes for various pathologies of the digestive system Keywords: Ultrasound (US),echogenicity,echogenicity coefficient,digestive system,dogs,stomach,intestines, Refference: I.

When studying the temporal organization of physiological functions, the rhythm parameters of physiological functions were determined, followed by processing the results using the Cosinor Analysis program, which reveals rhythms with an unknown period for unequal observations, evaluates 5 parameters of sinusoidal rhythms (mesor, amplitude, acrophase, period, reliability). The essence of desynchronization is the mismatch of circadian rhythms among themselves or destruction of the rhythms architectonics (instability of acrophases or their disappearance). Desynchronization with respect to the rhythmic structure of the body is of a disregulatory nature, most pronounced in pathological desynchronization. High neurotism, increased anxiety reinforces the tendency to internal desynchronization, which increases with stress. During examination stress, students experience a decrease in the stability of the temporary organization of the biosystem and the tension of adaptive mechanisms develops, which affects attention, mental performance and the quality of adaptation to the educational process. Time is shortened and the amplitude of the “initial minute” decreases, personal and situational anxiety develops, and the level of psychophysiological adaptation decreases. The results of the work are priority because they can be used in assessing quality and level of health.

Tsvetkov, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00047 Abstract: The present study of comparison methods based on the triadic model introduces the following concepts: the relation of comparability and the relation of comparison, and object comparison and attributive comparison. The difference between active and passive qualitative comparison is shown, two triadic models of passive and active comparison and models for comparing two and three objects are described. Triadic comparison models are proposed as an alternative to dyadic comparison models. Comparison allows finding the common and the different; this approach is proposed for the analysis of the nomothetic and ideographic method of obtaining knowledge. The nomothetic method identifies and evaluates the general, while the ideographic method searches for unique in parameters and in combinations of parameters. Triadic comparison is used in systems and methods of argumentation, as well as in the analysis of consistency/inconsistency.
