"Characterization of puma–livestock conflicts in rangelands of central Argentina." Royal Society Open Science 4, no. 12 (December 2017): 170852. http://dx.doi.org/10.1098/rsos.170852.
Full textAbstract:
Livestock predation is one of the major causes of conflicts between humans and pumas ( Puma concolor ). Using data from interviews with ranchers and kill-site inspections, we characterized puma–livestock conflicts in Villarino and Patagones counties of central Argentinean rangelands. Depredation was considered the major cause of livestock losses, and puma attacks were reported in 46.6% and 35.4% of ranches in Villarino and Patagones, respectively. The majority of ranches underwent losses smaller than 1000 USD. The proportion of livestock lost to predation (0.1–10.4%) and financial losses (5.3–1560.4 USD) per ranch/year varied across ranches, and small sheep ranches in Villarino were affected the most. Depredation was recorded only at night and preferentially in grassland with shrubs and cropland habitats. Although nocturnal enclosures appeared to decrease sheep losses, puma hunting was considered the most effective form of reducing depredation and was implemented by most ranchers. Mortality rates were 3.7 and 1.1–1.56 individuals/year × 100 km 2 for sheep and pumas, respectively. Nocturnal fencing, shepherding and spatial separation from predators may efficiently reduce sheep losses. However, the poor association between the intensity of puma persecution and puma-related livestock losses suggests that conflict mitigation in central Argentina is not only about reducing damage but also about increasing tolerance.

Full textAbstract:
This cross-sectional study was carried out to investigate the status of brucellosis in sheep management under extensive smallholder farming and intensively in governmental breeding ranches in six districts selected from three administrative zones. Using multistage sampling, serum samples of 2409 sheep from 274 flocks were collected and tested using the Rose Bengal Plate Agglutination Test (RBPT) and positive sera were confirmed using a Complement Fixation Test (CFT). Of all animals tested, 4.98% were RBPT positive, and after confirmation with CFT, the overall animal-level prevalence was found to be 4.89% (CI: 3.24-6.9%). Of the flocks sampled, 61 (22.3%, CI: 18.03-29.17%) had at least one animal positive to both tests. Significantly higher (P < 0.001) individual animal seroprevalence of 5.87% (CI: 3.83-7.31%) was found in sheep under smallholder production than in breeding ranches (1.75%, 95% CI: 1.57-3.05%). However, flock level seroprevalence in breeding ranches was found to be 100% (8/8), while in the smallholder production it was 19.92% (CI: 16.4-25.81%). Significantly highest animal-level seroprevalence of 9.55% (CI: 7.91-12.4%) was observed in north Wollo zone’s smallholder farms. From the three studied breeding ranches, highest seroprevalence of 3.57% (CI: 2.84%-5.18%) was found in Sheno Agricultural Research Centre. Significantly higher seroprevalence (P < 0.01) was found in aborted sheep and with history of retained fetal membrane in both production systems. All the sheep flocks in the studied breeding ranches were found to be seropositive; hence, this study suggests strict control measures of ovine brucellosis in the breeding reaches, since they could be a source of infection for the smallholder farms.

Full textAbstract:
Cryptosporidium spp. is a parasite that can infect a wide variety of vertebrate species. The parasite has been detected in sheep worldwide with diverse species and genotypes of various levels of zoonotic potential and public health concern. The purpose of this study was to determine the distribution of genotypes of Cryptosporidium in sheep in California, USA. Microscopic positive samples from individual sheep from central and northern California ranches were genotyped by sequencing a fragment of the 18S rRNA gene and BLAST analysis. Eighty-eight (63.8%) of the microscopic positive samples were genotyped, and multiple genotypes of Cryptosporidium were identified from sheep in the enrolled ranches. Approximately 89% of isolates (n = 78) were C. xiaoi or C. bovis, 10% of isolates (n = 9) were C. ubiquitum, and 1% of isolates (n = 1) were C. parvum. The C. parvum and C. ubiquitum isolates were detected only from lambs and limited to four farms. Given that the majority of Cryptosporidium species (i.e., C. xiaoi and C. bovis) were of minor zoonotic concern, the results of this study suggest that sheep are not a reservoir of major zoonotic Cryptosporidium in California ranches.

Full textAbstract:
The Patagonian rangelands are dominated by steppes interspersed with meadows (locally called mallines), which are small but permanently humid areas, characterised by high spring–summer quality and productivity of grasses and grasslikes. The region’s main economic activity is sheep ranching, either alone or mixed with goats and/or cattle, using horses as transportation animals. Overstocking has been signalled as one of the causes of rangeland degradation in this region. Knowledge of botanical composition of livestock diets provides valuable information helping in the design of management strategies to improve or maintain the forage resource. With this objective we studied the dietary botanical composition of domestic livestock on Patagonian ranches with and without mallines, at different seasons. It was found that the differences between diets of the same herbivore species on ranches with and without mallines were greater than the differences among the diets of the different herbivores species grazing in the same type of ranch. Grasses were the forage class most consumed by livestock in 76% of ranches without mallines and in 38% of the diets of ranches with them, with Stipa spp. being the main species consumed. Grass-like species were important in ranches with mallines, specially Juncus spp., and woody plants (Chuquiraga spp. as the most consumed) in ranches without mallines. Forbs hardly exceeded 10% in some spring diets of sheep, at both ranch types. Grasslikes constituted the major component of the spring and summer cattle diets, and constituted one-third of winter diets. For the rest of the herbivores studied, this forage class was important in spring–summer diets, but insignificant in the winter samples. Goats showed a greater use of the shrub in the less productive ranches and they were the most important consumers of shrubs on ranches with mallines during winter, which is the critical season of forage production. We conclude that the presence of mallines strongly condition the diet composition of the studied domestic herbivores. And, since the use of forage classes is different between these animal species, given a ranch type, the replacement of single-species grazing by mixed grazing can achieve the optimal possible use of the Patagonian rangelands.

AbstractLocally abundant ungulates often come into conflict with human activities. After a population collapse that reached its nadir in the 1970s, the guanaco Lama guanicoe population in Tierra del Fuego, Chile, recovered and is now in conflict with sheep ranching and commercial logging. We studied the effects of livestock density and environmental factors on guanaco abundance and spatial ecology, using seasonal counts and radio-telemetry in a private protected area (Karukinka) and neighbouring ranches in a forest–grassland mosaic in Tierra del Fuego. Guanaco density was highest in low-elevation areas with more grassland cover and little snow accumulation in winter. In low-elevation areas, guanaco density decreased with increasing livestock density. Radio-tracked guanacos exhibited a partial migration pattern: two individuals migrated seasonally, selecting grasslands and avoiding forests mainly in summer, whereas six sedentary individuals used habitats according to their availability. Migratory guanacos spent the summer in Karukinka and winter on nearby ranches. High sheep densities and poor range condition on the ranches reduce key forage resources available to guanacos and may promote use of forests by guanacos, affecting forest regeneration and increasing conflict with logging. Current guanaco harvest by loggers may fail to reduce the impact of guanacos on logged-forest regeneration if guanaco spatial ecology and sheep management are not considered. Our results provide insight into the interactions among guanacos, forests and livestock ranching, and may be used to reduce conflicts and guide conservation in the Fuegian ecosystem.

Rangeland cattle production is the largest agricultural sector of Uruguay. Ranches produce up to three products (beef, sheep-meat, and wool) usually combined into an equivalent meat (EM) index. The objective is to compare the empirical results from the estimation of a single output stochastic production frontier (SPF) and a multi-output stochastic ray frontier (SRF) to provide insights on the useof the EM index to evaluate ranches performance. Results show similar efficiency scores. The average level of TE is 0.769 for the SPF and 0.779 for the SRF. We cannot discard EM index as a simple measure of combined production.

Abstract Supplementation strategies and nutritional management of ewes during critical production periods of breeding and gestation is an important consideration, particularly when ewes are on winter range. Clinical and subclinical trace mineral deficiencies at these times limit ewe productivity in these extensive environments. The objectives of this study were to (1) quantify mineral element concentrations of common forages on winter range, and (2) evaluate producer supplementation strategies using a survey. We hypothesized that mineral element concentrations in winter forages were inadequate to meet ewe requirements during critical production stages and shrub species would contain higher levels of macro- and micro-mineral element concentrations than grass species. Forage samples were collected from 25 ranches across Wyoming winter range and were compiled by species and analyzed for nutrient and mineral element composition; however, data presented herein represents the first year of data collection (12 of 25 ranches). Nutrient and mineral element concentration results indicated an effect in CP, Ca, P, K, Mg, S, Na, Zn, Cu, Se, Mn, and Mo concentrations between grass and shrub species (P < 0.05). Specifically, Mg and Mo concentrations were higher in grasses while the other mineral element concentrations were higher in shrubs. No effect was observed for Fe and Co concentrations between grass and shrub species (P = 0.37 and P = 0.29). Survey results revealed that 80% of ranches had more than 1000 sheep, and 47% of respondents utilized winter range for 131 to 170 day periods throughout production year. While on winter range the majority of producers (47%) supplement with a protein source. Additionally, 58% do not supplement white salt, while 47% supplement a complete trace mineral mix.

IntroductionWildfires can injure animals both from burns and inhalation of smoke and particulates. In 2006 a rapidly moving grass wildfire burned 12 square miles in Yolo County. Approximately 1400 sheep on the range suffered variable degrees of burns. A coordinated effort of triage and individual treatment or humane euthanasia was performed by the UC Davis Veterinary Emergency Response Team.MethodsAnimals: Two sheep ranches with 1100 (ranch A) and 300 (ranch b) adult sheep of different breeds, ranging in age from 1-6 years of age. Initial owner evaluation: Both ranchers considered humane destruction of all sheep showing evidence of burned discoloration, estimated to be over 95% of 1400 sheep. Ranch B attempted shooting comprised sheep but stopped and requested aid from UC Davis as did ranch A. Veterinary initial evaluation and communications: Several burned sheep were visible from the roadway. Many sheep were standing with limited movement and some were recumbent. Triage was performed by bringing food and water sources to the sheep and those not eating and drinking were evaluated first. Gunshot euthanasia following AVMA guidelines based on veterinary determination of hopeless prognosis was used. Veterinary team members (N = 25) coordinated treatments, communications with public health, animal control, and press media, carcass disposal, volunteer management, and acquisition of office of emergency services resources.TreatmentTopical treatment of eyes and skin burns with silver sulfadiazine ointment, administration of systemic antibiotics (LA 200), pain relief (flunixine meglumine), wound debridement, and cesarean section of late term terminal sheep were performed.ResultsOver 500 sheep were euthanized by gunshot and the remainder (approximately 900) recovered lasting from 1-42 days. Progression of burn injury to skin, udder, face, and hoofs persisted for 42 days.ConclusionA coordinated veterinary response provided humane care and triage of this mass casualty animal emergency.

Full textAbstract:
Protected areas recently created in Argentina often include previously degraded lands, such as sheep ranches in the Patagonian deserts. We show the results of a 14-year monitoring program of three formerly persecuted carnivores, the culpeo fox (Lycalopex culpaeus), the South American grey fox (Lycalopex griseus) and the puma (Puma concolor), in two abandoned sheep ranches that were incorporated into a Patagonian national park approximately 25 years ago. The culpeo fox population underwent an average annual decline of 10–23%, whereas the grey fox and puma populations increased at an average annual rate of 7% and 19%, respectively. The grey fox’s increasing trends were strongly correlated with the decline of the culpeo fox, whereas the correlations between the fox and puma trends were weaker. Culpeo fox decline was stronger in the ranch where sheep and predator controls had been removed earlier. These relationships between species trends support the competitive release hypothesis, assuming that puma competition with the culpeo fox for trophic resources is stronger than competition with the grey fox, and that the puma can exclude culpeo foxes through interference. Species trends suggest a competitive hierarchy between fox species, with grey fox being the inferior competitor. However, mechanisms other than competition could not be discounted. Our study illustrates how long-term monitoring of interacting species allows a better understanding of ecological processes and wildlife ecology.

Thesis (MPhil (Agricultural Economics))--University of Stellenbosch, 2005.The Dorper Sheep species are exclusively bred for the dry arid conditions of some parts of South Africa. This species adapts easily and a prime lamb with great characteristics can be produced. There are two very important controlable factors regarding Dorper sheep farming namely herd management and cultivation. Herd management involves feeding, mating, mating methods and the handling of animals and their products. A few good objectives of herd management are the short breeding interval, low deaths and high performance rating. Genetic improvement can be achieved by using good rams, the selection of ewe-lambs as forthcoming breeding ewes, culling of uneconomic producers and the application of good breeding practices to improve meat production and reproduction. In this study a comparison is made between the management practices (herd management and cultivation) of Dorper farmers in 1990 and the management practices of Dorper farmers in 2004. For this aim the research of J.J. Ackermann (1990) was used. In 2004 questionnaires were send to Dorper farmers throughout South-Africa to get more information about their management practices. The conclusion of the study was that there was an increase in tertiary qualification of Dorper farmers from 1990 to 2004 and that more farmers used modern practices instead of the old traditional methods.

The main objectives of this study can be divided into three categories. In the first place it refers to the determination of production- and reproduction norms for the different main production areas in the greater Burgersdorp area, to promote production. In the second place it refers to the determination of the different management styles of sheep farmers in the greater Burgersdorp area. In the third place it refers to the calculation of gross margins for sheep farming in the greater Burgersdorp area, to establish the sustainable economic position. The survey area (the greater Burgersdorp area) includes the magisterial districts of Burgersdorp, Molteno, Steynsburg and Venterstad. The four magisterial districts were divided into two main production areas namely Stormberg Highveld and Burgersdorp Lowveld. Stormberg Highveld includes Molteno and the high-lying area (highveld) of Burgersdorp. Burgersdorp Lowveld comprises Steynsburg, Venterstad and the low-lying area (lowveld) of Burgersdorp. The management strategies of sheep farmers in the survey area were determined by means of a questionnaire and statistically analysed. The economic analyses of the sheep industry (wool and meat) were performed with the Geyer computer model. In this study it showed that the Dorper farmers obtained the highest gross margin per sheep. The lowest gross margin per sheep resulted from the Vleismerino farmers. Although the composition of the gross production value and the directly allocatable variable costs compare favourably, each main production area has unique management strategies for the different sheep breeds. The different management strategies can serve as the norm for extensive sheep farming, applicable to the specific main production area.

Full textAbstract:
One of the more important economic activities in the Altiplano region is raising livestock, the exploitation of cattle, sheep, and llamas which are raised and adapted to the conditions surrounding this activity. Livestock production plays a fundamental role in the economy of farming families by providing them products such as meat, milk, cheese, fiber, skins, and other products that each translate into monetary revenues. The present study was carried out in the community of "Chama 6 de julio," Ingavi Province, Department of La Paz, about 83 km. (51.6 miles) outside of La Paz at an elevation of 3,792 m. (12,440 ft.) above sea level. The annual precipitation is 370 mm. (14.6 inches) and average annual temperature is 12° C (53.6° F). The set objectives of this investigative work were: To evaluate the economic behavior of the livestock production (cattle, sheep, and llamas) at the small ranchers 14 level. To quantify in monetary units the structure of costs and revenues of livestock activity. To carry out a socio-economic analysis of the activity. The statistic parameters used were: measures of means, deviations, and percentages. Techniques used for gathering information include the following: semi-structured interviews, dynamic polls, dialogues, conversations, key informants, and direct observation. In studying the costs and revenues of livestock activity the conventional model of fixed and variable costs was used. The method utilized to evaluate the activity is an adaptation of the economic evaluation expressed by the indicating gauges Cost-Benefit Relationship (RBC) and Annual Investment Profitability (RI). 42 families dedicated to agricultural and livestock activity were involved in the study. They were functionally classified according to the number of cattle that they have on their land, a classification that resulted in four groups. The first group contained families possessing from 4 to 6 cattle; the second, from 7 to 9; the third, from 10 to 12; and the fourth, the families with 13 to 15 cattle. Also, the number of samples for each class was calculated to be 5 families. As livestock activity is the most important for families in this community, these families have most of their money invested in their herds, investments ranging from 73% to 86% of all their active livestock investments. The other 14% to 27% of their investment is in the livestock infrastructure, tools, materials, and equipment. The amount of land possessed by families in this community ranges from 8 to 40 hectacres (19.8 to 98.8 acres). The meat (cattle, sheep, and llama) is the most important product for commercial purposes. Accordingly, families from class IV achieved the highest production with 812 kg. (180.7 lbs) per year, followed by classes III and II. The lowest annual amount came from families grouped into class I with only 235 kg. (518 lbs). Another product of utmost importance after meat is cheese for which the families of class IV were those that had the highest annual production with 476 units, with an average weight of 0.6 kg (1.3 lbs). They were followed by families in classes III and I. Finally, the families in class II achieved the smallest output with 337 units. 69% to 79% of the total production of meat and cheese is destined for market. The families consume only 10% to 31% of what is produced. Variable costs represent 87.25% of the total expenses. On the other hand, fixed costs amount to only 12.73% of the total. Labor represents the greatest expense, reaching an average of 71.17% of the total expense. Relative to gross annual revenue, families in class IV reached the highest average numbers with 7,996.00 Bs. (Bolivianos). The lowest gross annual revenues correspond to those in class I with only 3,124.00 Bs. Classes III and II occupy intermediate positions between both former classes. Comparing the sources of gross annual revenue, cattle meat occupies the greatest portion with 40.81%. This is followed by cheese production, lamb, and llama meat with 30.84%, 23.30%, and 2.17% respectively. At the same time, cattle meat and cheese provide these farming families with 71.65% of their total gross annual revenue. The net annual revenues are positive only for families in classes IV and III with numbers at 312.00 and 156.00 Bs. On the other hand, classes II and I have negative net revenues at -3,039.00 and -2,455.00 Bs. The indicative Cost-Benefit Relationship (RBC) shows viability of the activity for families from classes IV and III with figures of 1.04 and 1.02. It is not as viable for families in classes II and I with numbers at 0.62 and 0.50. Estimates provided by the annual investment profitability (RI) are only satisfactory for those in classes IV and III with percentages of 4.6% and 2.13%. Unsatisfactory percentages result for classes II and I with -35.45% and -49.31%. According to the results obtained for the four classes, livestock activity carried out by farming families does not provide an acceptable profitability, even for families that have greater numbers of livestock (more than 12 cattle). It would be much less profitable for the families that have smaller herds of livestock.

Full textAbstract:
The transformation of the rangelands of the South Island of New Zealand during the pastoral era fits into the wider international context of European expansion into the 'new' world. European settlers displaced native peoples, introduced 'old' world animals and plants, and imposed a capitalist system that converted local resources into international commodities. In New Zealand the orthodox explanation of the pastoral impact on the rangelands claims that pastoralists introduced an unsustainable system of land use to the region. The pastoralists� indiscriminate burning practices and overstocking with sheep opened up the country to invasion by rabbits. Burning and overgrazing by sheep and rabbits stripped the natural fertility of the soils and left the country depleted, eroded, and overwhelmed by pests and weeds.
This thesis sets out to test those claims. It explores burning, the stocking of the rangelands with sheep and the impact of rabbits in detail. It also examines other land management practices, as well as sheep breeding, to see what impact they had on the landscape. The timeframe is set between 1841, when formal British settlement was established in the South Island, and 1912, by which time most of the great estates and stations had been broken up into smaller runs and farms.
The thesis uses station diaries, memoirs, contemporary newspapers and farming journals to assess what happened on the ground during the pastoral era. In particular, the thesis uses Mt Peel Station as a case study to examine the intensification in land use that took place between 1841 and 1912, in order to explain the transformation of the landscape and to answer the questions: what happened, how did it happened and why did it happened as it did?
These sources illustrate that the pastoral era was characterised by innovation. Pastoralists had access to technical and scientific information from around the world. Some conducted their own experiments to improve the productivity of the land and their stock. There was also a learning process involved in adapting their methods to fit the local rangeland environments. They were not simply rapacious capitalists out to strip the wealth from the land for their own personal gain; indeed, many pastoralists set out to establish viable and sustainable enterprises.
The thesis argues that the rangelands consisted of a variety of landscapes and climates. Differences in resource endowments had a considerable influence in shaping the environmental outcomes on different stations. Aridity and rabbits were two key factors in the depletion of the vegetation and the degradation of the landscape in the rangelands. Runs in semi-arid districts that were overwhelmed by rabbits suffered long-term damage. In districts where rainfall was more reliable stations that had been overrun by rabbits recovered remarkably quickly. Stations like Mt Peel, that were largely unaffected by the first rabbit plague, were able to maintain and even increase their productivity up to the time they were subdivided. The orthodox analysis of the transformation of the rangelands in the pastoral era does not account for these differences in outcomes.

Full textAbstract:
In Graaff-Reinet, domestic livestock farming and springbuck ranching are similar in that they both rely on the rangeland for their sustainability. However, as a consequence of repeated monotonous domestic livestock farming, resulting in compromised biological productivity and diversity, the rangelands have disintegrated. This, unfortunately, has placed the future sustainability of these rangelands and the livelihoods of the local people in an indeterminate state. In recent years, there has been an increasing interest in springbuck ranching for meat production as an alternative to domestic livestock farming in the area following (a) fears of worsening environmental challenges; (b) declining profitability in commercial domestic livestock farming and; (c) growing calls for the sustainable use of these rangelands for the benefit of future generations. The springbuck has emerged as a credible alternative to utilising the rangelands - as opposed to sheep - because of its promise to addressing the above challenges. This is in an attempt to tap into the multitude of benefits that the springbuck possesses (by virtue of being part of the natural capital of the area) that have a potential towards restoring ecological integrity by extenuating some of the detrimental effects of sheep farming on the rangelands and presenting opportunities for diversifying incomes. Yet, despite the general increase in interest, a resistance towards the uptake of springbuck ranching for meat production exists. The main contention is that springbuck meat production cannot out-perform the economic returns of wool sheep farming. This study attempts to address these concerns by investigating the profitability and economic sustainability of converting a sheep farm into a springbuck ranch in Graaff-Reinet. The study uses stochastic simulation to estimate the probability distribution of some key output variables, namely: net cash income, ending cash balance, real net worth and the net present value (NPV) in evaluating the profitability of converting a 5 000ha sheep-dominated farm into a springbuck-dominated ranch under three alternative scenarios. The use of stochastic simulation allows for the incorporation of downside risk associated with the production and marketing of wool, mutton and springbuck meat. The study uses stochastic prices and yields to calculate net returns variability. Incorporating scenario analysis helped to evaluate how alternative wool sheep-dominated and springbuck-dominated combinations would perform based on the probable outcomes of different assumptions in the various scenarios. By applying stochastic efficiency with respect to a function (SERF) criterion to the simulated NPVs, this study compares the profitability of alternative scenarios based on various risk aversion coefficients. The study finds that converting a 5 000ha wool sheep dominated farm into a springbuck dominated ranch could potentially be a more profitable investment than wool sheep farming over a 15 year planning horizon, in Graaff-Reinet. The SERF results indicate that for all scenarios tested, the best strategy of converting a wool sheep dominated farm into a springbuck ranch would be one which comprise a combination of 70% springbuck, 20% mutton and 10% wool production as the likely profitable enterprise mix. Using economic sustainability analysis, the study reveals that because of low costs in springbuck ranching, springbuck meat production enterprises are most likely to be more financially sustainable than wool sheep-dominated enterprises. This suggests that rangeland owners may be better off converting their wool sheep-dominated farms into springbuck-dominated ranches. Thus, as the call for more environmentally benign rangeland utilising economic-ecological systems intensifies, rangeland owners in the Eastern Cape Karoo have a practicable option. At the very least, there exists an option to broaden their incomes whilst promoting ecological restoration with springbuck meat production.

The objective of this study was to determine sheep production practices, constraints, flock dynamics, body condition and weight variation in two ecologically different resource-poor communal farming systems of the Eastern Cape Province of South Africa. Mean sheep flock sizes per household were not significantly different between the two ecologically different areas (villages); Gaga (19.0±3.10) and Sompondo (18.3±3.10). Shortage of feed, disease and parasite were reported the most important constraints across the two villages. In both villages, sheep housing was poorly constructed using acacia brushwoods. Fewer farmers owned rams: the rams to ewes ratio for the two villages were 1:20, 1:19 for Gaga and Sompondo, respectively. The low ram: ewe ratios reported suggest that inbreeding might have been reducing productivity of their flocks. There was also uncontrolled breeding due to undefined and mating seasons. Gall sickness, heart water and footrot caused most of the sheep mortalities. Dohne Merinos were the common genotypes in the two villages. Total entrances for each flock were higher (p < 0.05) in hot-dry season and hot-wet season than in other seasons. Most of the entrances were lambs and were born in hot-dry season (September) and cool-dry season (June) for larger flocks (10.90 ± 3.02) and for small flocks (3.65 ± 3.02). High lamb mortalities were experienced in the post-rainy (April) and hot-wet (December) season. There was a significant interaction between season and flock size. Most of the sales occurred in the hot-wet season. Ecological area had significant effect on sheep production potential (p < 0.05) in both flock classes. The average sheep production efficiency (SPE) value for Gaga and Sompondo were 0.50 ± 0.116 and 0.50 ± 0.096 respectively. The SPE for large flock was higher (p < 0.05) by season and flock size. Large flocks had a higher (p < 0.05) SPE values and the SPE ranged from 1.11 ± 0.193 in April, a post-rainy season month to 1.55 ± 0.193 in December, a hot-wet season month. Lamb mortalities constituted the greater part of outflows. High lamb mortalities occurred in hot-wet (December), hot-dry (September) and post-rainy (April) seasons. There was a significant interaction between season and age of sheep on body weight of sheep. Highest (p < 0.05) body weights were recorded in the post-rainy and autumn season in both lambs and ewes. It is therefore very important to come up with affordable interventions which take into play ecological differences of the areas for improved nutritional status of sheep in communal areas which will lead to improved sheep productivity and the poor-resourced farmer human nutritional and livelihood.

As the number of leisure farms grows, they are adopting diversified marketing model and attempt to attract tourists. There are many leisure farms allow the idol drama to take footages on the farm. Such information are even available from the official website of the agricultural authority. Idol dramas attract many viewers, and hopefully they could be attracted to visit the leisure farms. Whether this kind of activities meant a long-term recreational attraction, is worthy to be explored. This research screened popular idol dramas that were ended the broadcasting for at last more than 3 years and finds the Flying Cow Ranch and Ta Shee Blooming Oasis as the targeted leisure farms. The research designed and conducted survey on fans group of the idol drama, then statistical analysis were done on the collected data. The results were as following: 1. Respondents reported that they were attracted by the beautiful scene on the leisure farm and place high values to the farm’s landscape. 2. Attractiveness of the idol drama has a positive impact even in the long term on leisure farms. 3. Different demographic variables affected the viewers’ watching habits and the recreational attractiveness of the leisure farms. 4. The watching habit of the idol drama could affect attractiveness of the leisure farm.

Abstract Livestock ranches occupy the middle latitudes of Kenya. The land to the south is intensively used for agriculture and the extensive arid zone to the north is occupied by pastoralists. The ranching belt is of outstanding value for the conservation of wildlife. Most ranches carry abundant wild herbivores and some have black rhinoceros and elephant. Leopards and lions are increasing in numbers, however, and they kill increasing numbers of cattle and sheep, so alienating the ranchers from sympathy with conservation. The aim of this study is to record the density, home range and movements of leopards, their predation on domestic livestock and the prospects for control and management. The research is being carried out on a 200 km2 ranch north of Mount Kenya. Reconnaissance and survey have established the distribution of wild herbivores and the movements of leopards from spoor. Sixty baiting-points for leopards have been established and five males and five females have been trapped. Nine were immobilized and fitted with radio-collars.

This chapter analyzes how Falkland Islanders have adhered to and customized British imperial property ideologies of enclosure and improvement of the commons. It describes how the Falklands' property regime has transformed land tenure from a usufruct colony founded on debt bondage to an absentee-owned monopoly of community sheep ranches and the current system of privatized small family farms. It also reviews the localized terrestrial conditions that made the colony a significant producer of cattle hides and then sheep wool in the nineteenth and twentieth centuries. The chapter considers the historical stages of dominion and ownership in the Falklands/Malvinas in order to grasp the significance of the Islanders' property relations for their emergent bundles of rights claims. It highlights an anthropological approach that treats property as ownership and rights over pieces of land and as relations between and among persons with respect to soil.

Abstract The turn of the twentieth century witnessed the transformation of wilderness as an idea into wilderness as practice: the creation of parks and other areas permanently set aside from settlement. By this point, a body of influential Americans had become convinced that America’s abuse of nature had spiraled far out of control of such haphazard measures. Where were the enormous herds of buffalo that had once covered the Great Plains? Yellowstone, a few private ranches, and an isolated park in Canada housed the pathetic remnants of a population that had once numbered as much as 40 million. Flocks of passenger pigeons had once numbered in the billions, darkening the sky in flight and blanketing hundreds of miles of forest when at roost. Sports hunters and commercial hunters blazed away, convinced of nature’s inexhaustibility. The last known passenger pigeon, Martha, died a lonely death in a Cincinnati zoo in 1914, more than a decade after the last verifiable sighting in the wild.1 In parts of Wisconsin and Michigan, where majestic stands of red and white pines had once loomed, smoldering stumps stretched as far as the eye could see. Cattle and sheep trampled the meadows of even the most remote mountain valleys. Reflecting on such depressing developments, Theodore Roosevelt articulated a key conservationist sentiment when he concluded in 1897 that “[t]he frontier had come to an end; it had vanished.”2 Wilderness preservation was but one part of the larger response of conservationists to what they understood as nothing less than a crisis of their civilization.

Estella said yes. After such news, Aldo could hardly concentrate. He wrote home, “Somehow, this time, I don’t seem to be able to write.” On December 2, he wrote in his work journal, “In at least 6 lines of work today and nothing particularly accomplished in any one.” Aldo celebrated the holidays and his engagement at the Bergeres’ with his father beside him, warmly regaled with guitar music, Spanish and Italian carols, pasta, luminarias, and piñatas. Then came the promenade of New Year’s fiestas and parties honoring New Mexico’s statehood. Work looked pretty dull in comparison. On his return to Tres Piedras, Leopold found his desk buried under requests for grazing permits. Altogether, Carson headquarters had received applications for 220,000 sheep. The new plan allowed only 198,000, and it was Leopold’s job to reject the extra applications and to make the decisions stick. He and his rangers patrolled the forests, their six-shooters at their sides. Even so, they relied mostly on forceful words as a means of persuasion. When he met ranchers or sheepers to talk, Leopold carefully left his pistols in his saddle. By March, the business of permits was well under way. Hall had accomplished the job he came for, and he moved on. Ringland promoted Leopold to acting supervisor of Carson National Forest. Aldo boasted to his fiancée: “Of all the men in our class from Forest School there are only two of us Acting Supervisors, and none are Supervisors yet.” By fall, he was Carson’s full supervisor. Leopold hired more rangers to hold the grazing situation steady. He closely inspected the rangers’ stations, work journals, and reports. When a forester’s idea or accomplishment impressed him, he dashed off “Bully!” in the margin. That summer, Aldo built a house for his bride- to- be, assisted by Estella’s brother and his own brother Frederic, who was working at headquarters for the summer. Aldo’s correspondence to his beloved never faltered.

Full textAbstract:
Rangelands in Africa (i.e., grasslands, savannas, and woodlands, which contain both grasses and woody plants) cover approximately 2.1 × 109 ha. Africa’s livestock population of about 184 million cattle, 3.72 million small ruminants (sheep and goats), and 17 million camels extract about 80% of their nutrition from these vast rangelands (IPCC, 1996). Rangelands have a long history of human use and are noted for great variability in climate and frequent drought events. The combination of climatic variability, low ecological resilience, and human land use make rangeland ecosystems more susceptible to rapid degeneration of ecosystems. From a land-use perspective, there are differences between West Africa and East Africa in rangelands use. In arid and semiarid areas of West Africa (rainfall 5–600 mm), millet (or another crop) is planted over a unimodal (one peak in rainfall per year) rainy season (three to four months); then fields remain fallow during the dry season, ranging from eight to nine months. Livestock eat crop residues. Land use is dominated by cultivation, with livestock playing a subsidiary role in the village economy. In East Africa, by contrast, areas with higher rainfall (up to 600 mm) are inhabited by pastoralists rather than farmers. In dry parts, cultivation occurs mainly where irrigation is possible or where water can otherwise be sequestered and stored for cropping. Rainfall is bimodal (two peaks in rainfall per year) in most rangelands, resulting in two growing seasons. As much as 85% of the population live and depend on rangelands in a number of countries in Africa. With emerging problems associated with the increasing population, the changes in key production areas, and the prevalence of episodic droughts and insecurity due to climatic change and ecological degradation and expansion of grazing territories, the traditional coping strategies of farmers, ranchers, and pastoralists have become inappropriate. More uncertainties require new innovations in characterizing, monitoring, analyzing, and communicating the emergence of drought to allow pastoral communities to cope with a rapidly changing environment. To this end, the United States Agency for International Development (USAID) awarded the Texas A&M University System an assessment grant to develop a Livestock Early Warning System (LEWS) as part of the Global Livestock Collaborative Research Support Program.
