Resumen

Livestock plays a vital role in Somalia's economy, contributing more than 60% of the country's gross domestic product. However, livestock production in Somalia faces many challenges, including conflict, insecurity, climate change and environmental degradation. These challenges can lead to livestock losses, which can significantly affect the livelihoods of livestock owners. This paper proposes an Internet of Things (IoT)-based livestock tracking system to help farmers locate their lost livestock. The system uses GPS and GSM/GPRS technology to track the location of livestock in real-time. The system also includes a boundary restriction feature that can be used to ensure that livestock remains within a designated area. The IoT-based livestock tracking system has the potential to address a number of challenges facing livestock production in Somalia. The system can help reduce livestock losses, improve livestock management practices, and increase productivity. The system is currently being field-tested in Somalia. The system successfully detects livestock crossing the border and transmits the livestock's location in real-time. Field test results show successful real-time tracking of livestock. The test data will be used to improve the system and assess its effectiveness in helping farmers locate their lost livestock.

Resumen

Sustainability has been recognized as a fundamental principle of development so that humanity can survive on this planet. However, there are still difficulties in translating its philosophical principles into the ability to make concrete decisions for its consolidation. Three factors that determine growth on planet earth, directly related to agricultural systems, have been identified: agricultural production, management of natural resources, and pollution. Therefore, sustainable agriculture must consider them both for the management of plant and animal populations, since both modify the environment to adapt it to their requirements, thus regenerative practices arise to recover the ability of ecosystems to restore themselves. In that sense, it is intended in this review to elucidate how the concepts and principles exposed are translated into a regenerative or a sustainable livestock. To achieve sustainability, it is necessary and essential, an integral management of processes with a holistic vision of the system by farmers and technicians, leading human talents willing to learn different and new technologies, and motivated trained personnel in sustainable techniques that incorporate agroecological and regenerative practices, all on the basis of financial planning. Regenerative livestock per se as an emerging paradigm is very promising, but still requires local research. It is concluded that there is no single model of sustainable livestock, there are no recipes or technological packages, it is governed by the principles that aim at the balance of its dimensions (social, economic, environmental and institutional political governance).

Resumen

Abstract Livestock is a leading commodity in Subang Regency. Besides, Subang is one of the national priority commodity development areas for beef cattle. An innovative way is required to handle resource constraints and achieve the targeted goals. The research describes the community-based livestock disease control innovation, “Paket Hemat”, in Subang Regency, West Java Province, Indonesia. It used the case study method. Data was collected using documentation studies and interviews. This innovation unites and empowers the community of breeders in Subang Regency. The breeders were trained to become skilled in maintaining their livestock’s health and provide initial treatment when they have an illness, supervised by the Livestock and Animal Health Agency. Veterinarians or paramedics will handle further medical assistance if the initial treatment cannot overcome the problems. In 2017, 60 breeders were trained, and this increased to 120 breeders from 30 sub-districts in 2020. The evaluation results showed a decrease in livestock disease and an increase in livestock population from 2018 to 2020 in Subang Regency. Better livestock health status can increase livestock productivity and breeders’ welfare. Thus, disease control can reinforce the livestock’s role in poverty reduction and improve people’s welfare.

Resumen

Indonesia has great livestock potential. The semi-intensive grazing system is one of the efforts to increase the production of healthy and superior dairy or beef livestock. This grazing system has many advantages. However, it has several weaknesses that can prejudice farmers, including lost or stolen livestock due to a lack of control and monitoring. Therefore, tracking livestock’s position in the WSN-based grasslands monitoring will be implemented to overcome these weaknesses. Thus, it will provide benefits as a support for a modern and controlled livestock system. The built WSN consists of several nodes installed on livestock consisting of Arduino nano, GPS Neo Module, LoRa S-1278, DS3231 clock module, and MCU node. Tracking is visible through the application by displaying the map and livestock’s GPS position. In addition, the system is notified if the livestock’s position is located more than in the permitted radius of the farm. The system was examined and analyzed using the Haversine method with various scenarios to find the maximum range transmission and perform system toughness. The results stated that the system could track the livestock’s position up to 11 Km and the location error calculation obtained by Haversine is only 11.7% of the actual location.

Resumen

Agri-food systems approaches have gained international recognition over the last years. The role of livestock—both in mixed crop-livestock and pastoral systems—in sustainable agri-food systems transformation remains contested. In this review paper we present new analyses of original data from an international livestock expert survey, a quantitative search in Web of Science, and a literature review to unravel the potential for livestock systems to sustainably transform agri-food systems through regenerating soils and restoring degraded landscapes. We (i) illustrate how livestock is important for people and planet alike; (ii) review how to harness livestock's potential for rehabilitation of soils and landscapes; (iii) demonstrate successful case studies of livestock solutions such as improved forages for cut-and-carry systems and grazing management; and (iv) identify four critical steps required for lasting change at continental scale. We conclude that livestock solutions can be key catalysts for sustainable agri-food systems transformation that merit accelerated public and private investments. More research is needed to develop concrete, operational and practical livestock solutions, and measure, monitor and report their contributions and progress toward the 2030 Agenda for Sustainable Development.

Resumen

Livestock is one of the fastest-growing sectors, especially in emerging economies, to meet the projected demand for protein for the growing population. Livestock’s role is beyond its contribution to meat and milk. It affects food security in multiple ways. The current study is designed to assess the food security status of households having livestock and the caloric contribution of livestock in the consumption profile of households. For this purpose, a sample of 456 households was collected from three districts (152 from each Bahawalpur, Faisalabad, and Rawalpindi) of Punjab, representing the southern, central, and northern regions of the province. The calorie intake of households is assessed by studying the consumption profile and evaluation of generated energy in terms of calories to assess food security. The contribution of livestock is estimated from cumulative energy generated in the form of calories from the consumption of livestock products. Data analysis reflects that 59% of Bahawalpur households are food secure compared to Faisalabad, where 63% of households are food insecure. Similarly, Rawalpindi has 60% of households with food security status. The households with livestock and whose women participate in livestock activities extract 20% of their nutrition from animal sources in Bahawalpur, 20% in Faisalabad, and 30% in Rawalpindi. The overall food security situation can be improved by increasing the share of livestock products in the household’s consumption profile.

Resumen

Accounting for livestock activities affords particular accounting questions pertaining to asset valuation and profit measurement. The livestock industry impacts significantly on the Australian economy, but accounting information produced by firms in the industry has escaped accounting regulation. Traditional accounting theory suggests that uniformity in reporting provides optimal information for users of accounting reports and that lack of appropriate regulation results in diversity in reporting practices. Livestock represents one category of self-generating and regenerative assets [SGARA] and the purpose of this thesis is to develop recommendations on livestock accounting practices to assist in developing an accounting standard for SGARA generally. In achieving this aim, the thesis considers existing guidelines developed by professional bodies in other countries, professional recommendations and research papers produced in Australia and current Australian practice as revealed by the published accounting reports of Australian Companies. Despite the small sample available, published reports show marked differences in accounting policies and in the level of disclosure. Classes of livestock held, and the purposes of holding livestock vary. Most firms in the Australian livestock industry are not reporting entities. The more uncommon forms oflivestock tend to be held by non-reporting entities. Accordingly, accounting recommendations concentrate on traditional categories such as sheep and cattle. The major recommendation is the valuation oflivestock at net market value. Changes in value influenced by entity management are reflected in profit or loss for the period. Unrealised changes in value resulting from movements in market prices are transferred to a livestock revaluation reserve.

Resumen

Although diarrhoea caused by Cryptosporidium is prevalent in livestock species throughout the world relatively little is known about the species and subtypes of Cryptosporidium found in cattle on Scottish farms. In particular, little is known about the shedding profiles (age when calves become infected and duration of shedding) of the different species found in cattle and how calves become infected. There are several theories about how neonatal calves first become infected with the parasite but the role which adult cattle play in the transmission of the parasite has not been fully addressed. It was previously thought that adult cattle did not become infected with the same species of Cryptosporidium which causes disease in the young calves. Some studies have shown that this may not be true and with the advance of new techniques to discriminate species this is an area which should be revisited. In addition, it is known that it is possible for humans to become infected with Cryptosporidium and show clinical disease early in life and then again later in adulthood. In livestock however, diarrhoea caused by the parasite is generally only seen in neonatal livestock while older animals tend to be asymptomatic. It is not known if this resistance to clinical disease at an older age is due to changes in the host with an increase in age or if prior infection “immunises” the animal and provides protection against re-infection. It is also not known if infection with one isolate of C. parvum will provide protection against infection with another or if the protection formed is species/isolate specific. The main aims of this thesis were to: determine the species and subtypes of Cryptosporidium found in calves on a study farm over a one year period from birth; assess the role which adult cattle play in the transmission of the parasite to newborn calves; develop new typing tools to enable the rapid and easy differentiation of Cryptosporidium species found in cattle and to examine the host-pathogen interactions in animals given serial experimental challenges with distinct Cryptosporidium parvum isolates to determine if the resistance seen in older animals on farms is due to an increase in age or as a result of prior infection. iii A variety of different approaches were taken to achieve these aims. Longitudinal experiments carried out on a study farm revealed that in calves < 9 weeks of age the most common species of Cryptosporidium is C. parvum and that all calves in the group became infected with Cryptosporidium within the first two weeks of life. Sample collection from the same animals later in life (at 6 months of age) showed that contrary to most previous studies the most common species detected at in this age group was also C. parvum although, interestingly, the subtype which the calves were shedding was not the same subtype that they were shedding previously. The longitudinal study which investigated the role of adult cattle in the transmission of Cryptosporidium also yielded some interesting results. It was found that most of the adult cattle on this farm were shedding Cryptosporidium albeit intermittently. Speciation of the positive samples revealed that, on this farm, the most predominant species of Cryptosporidium in adult cattle was also C. parvum. This is very unusual as most previous studies have not found this level of infection in older cattle and C. parvum is not usually found in this age group. A number of different subtypes were found in adult cattle and some animals shed more than one subtype over the course of the study. This contradicts prior findings which demonstrated that only one subtype is found on a single farm. The experimental infection trial involving infection of young (<1 week old) and older (6 week old) lambs with distinct C. parvum isolates demonstrated that an increase in age at primary infection reduces the effect of clinical disease. Animals which were infected at <1 week of age were re-challenged at 6 weeks of age with either a homologous or heterologous infection. Results revealed that previous exposure does not protect against re-infection with the same or a different isolate of C. parvum. This study also demonstrated that an increase in infective dose leads to a shorter pre-patent period and that there are variations in the clinical manifestations of different isolates of the same Cryptosporidium species.

Resumen

The use of livestock guarding dogs (LGDs) to mitigate farmer-predator conflict in Namibia was evaluated. As farmer-predator conflict has two sides, LGDs were evaluated in terms of livestock production and conservation. The main objectives in terms of livestock production were to document: 1) the perceived ability of LGDs to reduce livestock losses in a cost-effective manner; 2) the farmers’ satisfaction with LGD performance; and 3) factors influencing LGD behaviour. The main objectives in terms of conservation were to record: 1) predator killing by farmers relative to LGD introduction; 2) direct impacts of LGDs on target (damage-causing) species; and 3) the impact of LGDs on non-target species. This evaluation was conducted on LGDs bred by the Cheetah Conservation Fund (CCF) and placed on farms in Namibia. The data were collected during face-to-face interviews with farmers using LGDs. Historical data from the CCF programme were used in conjunction with a complete survey of the farmers in the CCF LGD programme during 2009-2010. In terms of livestock production, 91 percent of the LGDs (n = 65) eliminated or reduced livestock losses. Subsequently, 73 percent of the farmers perceived their LGDs as economically beneficial, although a cost-benefit analysis showed that only 59 percent of the LGDs were cost-effective. Farmers were generally satisfied with the performance of their LGDs. However, farmer satisfaction was more closely linked to good LGD behaviour than the perceived reduction in livestock losses. The most commonly-reported LGD behavioural problems (n = 195) were staying at home rather than accompanying the livestock (21 percent) and chasing wildlife (19 percent). LGD staying home behaviour was linked to a lack of care on subsistence farms, as high quality dog food was not consistently provided. Care for LGDs declined with LGD age on subsistence, but not commercial, farms. In terms of conservation, predator-killing farmers killed fewer individuals in the year since LGD introduction than previously; this result was only significant for black-backed jackal Canis mesomelas. However, 37 LGDs killed jackals, nine killed baboons Papio ursinus, three killed caracals Caracal caracal and one killed a cheetah Acinonyx jubatus (n = 83). Farmers and LGDs combined killed significantly more jackals in the survey year than the same farmers (n = 36) killed before LGD introduction. Conversely, five farmers killed 3.2 ± 2.01 cheetahs each in the year before LGD introduction, whereas LGDs and these farmers combined killed only 0.2 ± 0.2 cheetahs per farm in the survey year. Only 16 LGDs (n = 83) killed non-target species. The high LGD success rate in terms of livestock production was facilitated by livestock husbandry practices in the study area. In terms of conservation, LGDs were more beneficial for apex predators than for mesopredators and had a minor impact on non-target species.

Resumen

In response to sustainable land management requirements and catchment-scale hydrological modelling needs, scientific interest in hydrological'connec~ivity'hasgrown. However, little is ~ . known about how hydrological connectivity is impacted by management. While there has been much research into livestock grazing and soil erosion in the UK; relatively little research has been conducted to characterize the hydrological patterns of livestock impacts, especially in organic soils which might be more vulnerable to environmental degradation. This thesis examines livestock impacts, as a land use case study, to conceptualize the 'dynamic nature of hydrological connectivity and its potential changes on hillslope and catchment hydrology. Different grazing strategies on organic soils (blanket p~ats and peaty gleys) in the uplands of Upper Wharfedale and Teesdale and organo-mineral soils (stagnogleys) in lowlands at Kirkby Overblow, northern England are investigated. Field measurements and monitoriIig are combined with laboratory experiments and proces~-based distributed modelling. Results suggest that compaction effects from sheep differ between soil types and topographic context but that they were generally confined to the upper 20 cm of the soil profile but with greater impacts in the upper 5 cm. Light-medium grazing (-9 a ha-1 ) significantly raised mean bulk density compared to adjacent soils with no grazing in the upper 10 cm of the soil profile of'stagnogleys. The relatively heavy grazing associated with frequently trampled areas under sheep tracks on stagnogleys was associated with soils with a mean bulk density 10 % greater (in the upper 10 cm of the soil) than those in the surrounding lightly grazed soil for stagnogleys, 2 % in 0-5 cm arid 9 % in 5-10 cm layers of peaty gleys, and at least 50 % in the near surface of peats. The effects of sheep tracks on soil properties and hydrological function were found to extend by at least 2 m further either side ofthe track rather than just being a feature ofthe visible track alone. Removing sheep led to a substantial fall in compaction effects in peats (10.4-21.7 % in bulk ~ensity) and stagnogley soils (0.5 % in bulk density) within a short time period (4-6 years). There were also significant differences in jnfiltration rates between short-term exclosure sites ' and grazed sites. For peat soils differences between lightly graZed areas and the long-term ' exclosures (35-45 years) were not much greater than those between the lightly grazed areas and the short-term exclosures suggesting that soil response to removal of sheep can be rapid. This thesis demonstrated that both the value and actual spatial distribution of livestock may .significantly decrease vertical connectivity and increase lateral connectivity, and hence increase both the spatial and temporal frequency of overland flow. In the organic soils of the humid-temperate zone studied this is through alteration of saturation-excess processes rather than infiltration-excess flow generation; antecedenfwater stores or soil moisture content are therefore of great, importance in hydrological connectivity responses to livestock impacts. Sheep tracks can be crucial in producing more rapid and connected overland flow on peats and stagnogleys, and effects extend several metres ether side of the track. Blanket peats are more vulnerable to livestock grazing than stagnogleys. The modelling approach used on stagnogleys from Kirkby Overblow suggests that increasing sheep density in very wet environments would lead to enhanced flood risks in terms of overall runoff amount and more rapid response due to e$anced coupling of hillslope arid river corridors, especially in extreme rainfall conditions.

Resumen

A cell based system for the production of transgenic animals would offer significant advantages, allowing in vitro analysis of transgenes before the production of whole animals, precise placement of transgenes and the possibility of deletion, replacement or mutation of endogenous genes. In mice embryonic stem cells provide a tool for such precise genetic manipulation. However, despite considerable efforts, neither ES nor EG cells capable of contributing to the germline of any livestock species have been isolated. This dissertation describes cell mediated transgenesis by in vitro transfection of cultured cells followed by nuclear transfer. Several different cell cultures were assessed for their suitability for nuclear transfer. Viable lambs were obtained from embryonic, fetal and adult somatic cells. This demonstrated for the first time that cellular totipotency is not irreversibly lost during differentiation. Some but not all of these cell types could support cell mediated transgenesis. A genomic Factor IX construct designed to express in the lactating mammary gland has been generated and used to demonstrate nuclear transfer as a means of transgenesis. Viable Factor IX transgenic female lambs were derived, and shown to express high concentration of the recombinant protein in their milk. These now provide the prospect of recombinant Factor IX as a safe alternative to human serum derived protein for the treatment of Haemophilia B. Also reported are preliminary experiments to assess gene targeting in farm animals. An ovine HPRT targeting vector was constructed. Inactivation of the ovine HPRT locus was attempted using fibroblast cells capable of supporting development after nuclear transfer.

Resumen

Working dogs contribute to many human endeavours. However, minimal research exists into Australia’s largest group of working dogs – the livestock herding dog. This knowledge gap exposes the sector to the risks of sub-optimal efficiency, compromised productivity and unacceptable animal welfare outcomes. This thesis aims to address this void by characterising the problem of livestock herding dog wastage and contributing to the incremental process of improving management, selection and breeding practices. Data from a questionnaire completed by 812 livestock herding dog owners on 4,027 dogs revealed that livestock working dogs typically provide a lifelong working contribution valued at approximately A$40,000, representing a 5.2-fold return on investment. At least 20% of livestock herding dogs are culled prematurely from work. Behavioural causes were cited for 89% of these failures. Management and owner characteristics associated with failure rates included; acquisition practices, housing methods, training approach, exercise frequency and owner personality and attitude to investment in their dog. To identify traits important to success, a selective sweep analysis comparing the genomic haplotype architecture of working and show Kelpies was undertaken. In the working Kelpie, a selective sweep spanning three megabases on chromosome 3 was identified in the region of genes related to fear-memory formation and pain perception. The Herding Dog Assessment Form - Personality (HDAF-P) was devised to collect behavioural data on herding dogs. Application of the HDAF-P to 261 working Kelpies provided a database of behavioural scores for 17 traits salient to working ability with those correlated most strongly to the owner’s assessment of overall ability being revealed as; initiative (T = 0.42, p < 0.001), intelligence (T = 0.38, p < 0.001), persistence (T = 0.38, p < 0.001), confidence (T=0.37, p < 0.001) and calmness (T=0.32, p < 0.001).

Resumen

Livestock production characteristics on the Navajo Reservation were studied to quantify and characterize herd demographics, feeding practices, management practices, marketing practices, and attitudinal orientations of producers. A stratified random (by grazing Agency) sample of the population (n = 10,000) yielded 125 possible respondents from each Agency. Face to face interviews were conducted by Navajo district grazing committeemen in the fall of 1997 for a total of 257 completed surveys. Navajo livestock producers were subsistence-level producers, who battled low birthing rates, slightly elevated mortality rates, diminished resource capacity, and challenges to economical feeding regimes. Most Navajos believed that livestock were an important part of their family's financial well-being; the Reservation was overgrazed; and that Navajos should be allowed to fence their land over their neighbors' objections. Navajo livestock production can be improved through education and greater articulation of the resource base. More detailed data collection is warranted to provide greater insight into production characteristics.
