This research was conducted within the context of smallholder livestock production and government attempts to improve this through a transfer of technology approach. Participatory action research (PAR) was used to enable action for change to emerge, while the research provided understanding and a basis for this action. Tombolo village in South Sulawesi, Indonesia was the location for this research, which first identified the problems and needs of the farmers, and then participatively developed strategies to meet these needs. Fodder security throughout the year was found to be the major constraint to cattle production. Forage technology was introduced, including fodder tree legumes and grasses, resulting in improved livestock production and many associated livelihood benefits. The introduction of these new technologies was adapted by stakeholders to local issues and needs. The extension services had previously aimed to improve livestock production through breeding and veterinary health measures, and had assumed that sufficient fodder was available for livestock. The formation of a learning group of farmers, who used group discussion to set their own agenda, was employed to identify this shortcoming, and how to sustainably overcome it. Participants were able to apply their experience and enhance their cognitive skills to find new meanings and knowledge to plan and take actions to improve their practice and situation. This thesis documents the process of change required to move from a “Transfer of Technology” approach to a “learning approach”. The research has shown that there is considerable potential for the application of PAR to rural community development in Indonesia. More specifically in Tombolo village PAR enabled farmers and extension staff to be empowered by becoming active participants in the research process and take action to improve their own practice. It helped them to analyse the situation to make the technology more appropriate, while also learning how to change the extension methods used towards one in which all stakeholders became partners in developing their situation / Doctor of Philosophy (PhD)

Com esse fundamento o presente trabalho buscou analisar quais os efeitos nos parâmetros produtivos dos bovinos com a ingestão da água tratada magneticamente. Assim neste trabalho realizou primeiro uma Revisão Bibliográfica Sistemática (RBS) sobre o uso água tratada magneticamente (ATM) em animais, que permitiu uma contextualização teórica sobre a metodologia e os principais resultados obtidos em pesquisas de relevância da área em estudo. Posteriormente verificou-se os efeitos do uso da água tratada magneticamente, na bioquímica sanguínea de bovinos de corte, peso final e qualidade do acabamento da carcaça. Os resultados iniciais mostraram que a água tratada magneticamente não apresentou inferência nos índices bioquímicos de K, iCa, Cl e Colesterol, assim como não alterou o peso final ou o acabamento de gordura de machos não castrados. Por fim desenvolveu-se um sistema de apoio à tomada de decisão, com base em modelagem com lógica fuzzy, para avaliação da carcaça de bovinos de corte. Esse sistema permitiu uma modelagem objetiva, que pode levar aos frigoríficos uma melhoria nos critérios de avaliação, permitindo que as carcaças tenham pontuações mais especificas com melhor qualidade atribuída. / Abstract: In face of the competitiveness of the meat market, the search for greater productivity through new technologies and the better classification of bovine carcasses can be a differential that increases profitability for producers and slaughterhouses, as well as delivering superior meat to the consumer . With this foundation the present work sought to analyze the effects on the productive parameters of cattle with the intake of magnetically treated water. Thus, in this work, the authors first carried out a Systematic Bibliographic Review (RBS) on the use of magnetically treated water (ATM) in animals, which allowed a theoretical contextualization about the methodology and the main results obtained in researches of relevance of the study area. Subsequently, the effects of the use of magnetically treated water in the blood biochemistry of beef cattle, final weight and finishing quality of the carcass were verified. The initial results showed that the magnetically treated water had no inference on the biochemical indexes of K, iCa, Cl and Cholesterol, nor did it alter the final weight or fat finishing of uncastrated males. Finally, a decision support system was developed, based on fuzzy logic modeling, to evaluate the carcass of beef cattle. This system allowed an objective modeling, which can lead the refrigerators an improvement in the evaluation criteria, allowing the carcasses to have more specific scores with better quality attributed. / Mestre

Thesis ( M. Sc.((Agricultural Economics)) -- University of Limpopo, 2017. / Wildlife farming has become an important land use alternative, especially in most developing countries where there is an abundance of wildlife resources. In South Africa, integrated wildlife/livestock was mostly practiced by commercial farmers on a privately owned land but in recent years, potential for income generation in the industry has grown. Smallholder farmers are increasingly being assisted to explore practicing integrated wildlife/livestock on communal land after receiving land through restitution programme. The aim of the study was to examine costs and benefits associated with integrating livestock with wildlife in a smallholder agricultural context. Structured questionnaires were used to collect data from 71 respondents situated in Ba-Phalaborwa Municipality selected using multistage random sampling technique. Cost-benefit approach and weighted decision matrix were used for economic analysis and also to identify potential trade-offs. Furthermore, the study used descriptive statistical analysis to identify opportunities and challenges faced by farmers. Some of the livestock costs identified include feeds, vaccines and labour costs. Benefits of wildlife include income from trophy hunting and selling meat from wild animals. Cost-Benefit Ratio (CBR) as a tool of cost benefit analysis techniques, was used in order get 0.67 in livestock farming, this shows that the project may not be sustainable whereas that of wildlife farming was 1.13 which indicate that the project will yield positive outcome for community involved. There are trade-offs that farmers will have to consider when shifting towards integrated wildlife/livestock such as reduced livestock benefits and increased wildlife benefits. Livestock diseases, stock theft and others are the identified challenges associated with integrated wildlife/livestock. Descriptive results indicated that 40% of livestock farmers mentioned that they are strongly affected by stock theft and disease transmission. The identified opportunities of integrated wildlife/livestock were business and job creation for rural households. Given the findings, the study therefore, recommends that government and private sector should assist farmers with training in wildlife farming so that they can be competitive in commercial wildlife farming. Funds should be made available for setting up infrastructure suited for wildlife land uses. / Department of Agriculture, Forestry and Fisheries (DAFF)

Thesis (PhD (Forest and Wood Science))—University of Stellenbosch, 2007. / Sustainable livestock production in semi-arid Botswana could be improved through tree planting on-farm to provide much needed protein and shade. Such action can be encouraged if the growth, productivity, nutritional value of trees and their contribution to mass gain of livestock are known.. A study at Malotwana investigated two indigenous species, Acacia galpinii and Faidherbia albida, and two exotic species, Leucaena diversifolia and L. leucocephala, at three spacings in a randomised complete block design replicated five times. The three spacings represented 400, 317 and 241 trees per hectare. The study was conducted over 6.5 years. Indigenous trees were sampled biennially and exotics annually to evaluate crown width, height, stem diameter, stem number and stem volume index. Complete plant harvesting of exotic trees at 2.5, 4.5 and 6.5 years evaluated agroforestry production. Leaves from all four species and pods of exotic species were analysed for chemical composition. Two groups of eight lambs were balanced for mass at selection for an on-farm feeding trial. Browse from exotic trees, comprising a 2:1 ratio of pods to leaves, was fed at 30% as supplement to hay to one group whose mean mass was contrasted with that of the control group fed sorghum bran at 30%. A. galpinii was a promising species, adaptable to planting away from its origin. Its crown width ranged from 5.86 m in high density plots to 6.08 m at low density and was significantly different among stands (p = 0.0406) at 6.5 years. Diameter at breast height (dbh) was significantly different among stands aged 6.5 years (p = 0.0003) and ranged between 10.38 cm at high density to 12.48 cm in low density plots, demonstrating a capacity to provide both shade and poles on-farm. At 4.5 years, F. albida attained a mean height of 4.5 m and 4.5 cm in dbh but suffered 67% mortality during a severe drought. Annual fodder production of 0.647 and 0.996 metric tonnes ha-1 for leaves and pods of L. diversifolia and 1.237 and 1.431 for L. leucocephala was recorded in years of average rainfall. Yields of 0.3 and 0.59 metric tonnes ha-1 were recorded for both species in the driest year. Equally good agroforestry production was obtained from both low and high density stands suggesting that low density plantings, which foster higher plant survival and reduce disease incidence, are best suited to the semi-arid conditions of Botswana. The crude protein of leaves ranged between 16.26 (L. diversifolia) and 25.25% (F. albida). They were highly digestible with more than twice the calcium content livestock require. Crude protein and digestibility measures were significantly different among leaves and varied significantly at different spacings (p<0.0001). Pods of the exotic species contained significantly more protein than the leaves (p<0.0001). Lambs supplemented with browse gained 102.33 g per animal per day while the control group gained 83.95 g. There were significant differences between groups during growth (p<0.05). Growing of A. galpinii, complemented with L. diversifolia and L. leucocephala, can supply short and long term feed, and greatly enhance livestock production while diversifying farm feed sources

Livestock production is the primary financial resource for most farmers in Mpumalanga province. Although commercial farmers require necessary equipment and technology to maximise their production and profit, but emerging small-scale farmers in the province face many challenges which have hindered their efforts to improve their livelihood, besides intervening in the procedure of commercialisation. Therefore, this study investigates the socioeconomic characteristics of the livestock farmers in the province, the determinants of market access and those influencing marketing inefficiency, with a view to developing policy recommendations. Structured questionnaire was administered to 300 farmers in order to capture information on market access and factors that could influence marketing inefficiency. Descriptive statistics was utilised regarding basic characteristics of the households. A logit regression model was used to analyse market access (sale of livestock through formal markets) using STATA. Marketing inefficiency was computed as the reciprocal of marketing efficiency which was calculated using Shepherd formula, while the two stage Least Square regression was applied for factors influencing marketing inefficiency after identifying market access endogenous variable. The study’s extrapolations indicated that 7 variables were consequential at 1% and 5% significance level with market access, namely transport ownership, transport cost, market price information, advertisement, farmers’ perception, marketing channel used and municipality. In addition, the results of the two stage least square model indicated that only 3 variables had remarkable significance with regard to marketing inefficiency. These are market access, livestock composition and infrastructure. The findings of the study evidenced that to reduce marketing inefficiency, then it is paramount to enable the easy dissemination of information and improving infrastructure so as to give small-scale farmers easy access to the markets. Consequently, addressing marketing constraints will provide an insight that will allow development of strategies to deal with those problems correctly and more efficiently. The study recommended that focus should be centred on addressing the constraints existing in livestock marketing system to enhance access to markets by encouraging youth participation in agricultural activities and providing training programmes and easy access for marketing related information. Also, infrastructure deserves to be given more attention by renovating the marketing facilities especially road networks in rural areas. In addition, extension officers and veterinary services are to provide help and support in preventing infections and diseases in order to minimise the losses. / Agriculture, Animal Health and Human Ecology / M.

This study attempts to identify factors responsible for determining differences in the productivity of cattle managed by communal and private livestock farmers in the southern region of Botswana during 1999/2000. It is hypothesised that herd productivity and investment in southern Botswana are higher on private ranches than on open access communal grazing land. This study is important because livestock, especially cattle, contribute significantly to the livelihood of farmers in Botswana. Cattle are a major source of meat, milk and draught power, and provide a store of wealth that protects against inflation and which can easily be converted into cash. Cattle production is also an important source of employment in the rural economy of Botswana. Furthermore, the export of beef is a major source of foreign exchange earnings, and cattle account for 80 percent of agriculture's contribution to Botswana's gross domestic product. A stratified random sample survey of communal and private livestock farmers was conducted in the southern region of Botswana from August 1999 to May 2000 with the assistance of four enumerators. The sample survey data were used to compute descriptive statistics and to estimate the parameters of a block recursive regression model. The model postulated relationships between agricultural credit, investment in fixed improvement, investment in operating inputs and herd productivity. Some of the equations are estimated with Ordinary Least Squares (OLS) and some with Two-Stage Least Squares (2SLS) to account for likely correlation between endogenous explanatory variables and the error term. Descriptive statistics show that levels of investment and herd productivity are higher on private farms than on open-access communal grazing. Private farmers are also better educated, more liquid, and have larger herd sizes, but do not differ from their communal counterparts in terms of age, gender, race or household size. The regression results show that (a) respondents with secure tenure and larger herds use more agricultural credit than those who rely on open access communal grazing land to raise cattle; (b) secure land tenure, higher levels of liquidity and use of long-term credit promote investment in fixed improvements to land; (c) liquidity from short-term credit and wage remittances supports expenditure on operating inputs; and (d) herd productivity increases with greater investment in fixed improvement and operating inputs. Herd productivity is therefore positively (but indirectly) influenced by secure land tenure. It can therefore be inferred that government should (a) uphold private property rights to land where they already exists; (b) privatise open access grazing to individual owner operators where this is politically, socially, and economically feasible; and (c) where privatisation to individuals is not feasible, government should encourage users to convert the grazing into common property by subsidising the costs of defining user groups and the boundaries of their resources, and enforcing rules limiting individual use of common property. This first-step in a gradual shift towards more secure tenure should be followed by the conversion of user groups to non-user groups organized along the lines of investor-owned firms where members exchange use rights for benefit and voting rights in a joint venture managed by an expert. / Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2006.

Long-term trends in rangeland sward dynamics (species composition, structure, productivity) were examined on three trials established between 1989 and 1996 at Kokstad Research Station in the Highland Sourveld, while animal performance (average daily gain and gain per hectare) was examined on two of the trials. The region enjoys moderate rainfall of 782mm per annum, with hilly topography, and soil depths ranging from >1m to <20cm. The first trial was labelled the simulation trial, as it simulated a four-paddock rotational grazing system, in which animals spent two weeks in each of three paddocks while the fourth was rested for the entire season. The rested paddock was rotated each year. The trial tested two stocking rates (0.5 and 1.0 AU.ha-1) at five ratios of cattle to sheep, ranging from cattle only to sheep only. The trial was unreplicated, and was established in 1989 on flat topography with deep soils. The second trial (labelled the flat two-paddock trial) was established in 1992 adjacent to the simulation trial. The trial examined two stocking rates of sheep weaners (0.5 and 1.0 AU.ha-1 seasonally) in a continuous grazing two-paddock system, in which one paddock of each treatment was burned and grazed continuously while the second paddock was rested, to be burned and grazed in the following season. The trial was replicated twice. The third trial (labelled the steep two-paddock trial) mimicked the grazing system of the flat trial, but was located on a steep (c. 20%) West-facing slope with shallow soils. The trial incorporated two additional treatments: an intermediate stocking rate of 0.7 AU.ha-1 and an ungrazed treatment. Species composition of the sward was recorded biennially on all trials using the nearest plant-point technique with between 200 and 800 points per paddock. Sward standing crop was measured in the rested seasons of the simulation trial and at the beginning, middle and end of each season in one paddock of each two-paddock treatment of the two-paddock trials. In the two-paddock trials, sward standing crop was measured within and outside permanently placed exclosure cages. Animals were weighed fortnightly. The response of species to grazing pressure or animal type was mediated by soil depth and slope, as well as the grazing system. Tristachya leucothrix declined on all grazed treatments. The ungrazed treatments remained relatively stable over ten years. On the low stocking rate treatments of the steep trial, unpalatable species increased, but so did Themeda triandra. The heavily grazed treatment of the steep trial was surprisingly stable, with little significant change in relative abundance of key species other than an increase in the unpalatable Alloteropsis semialata and decline in T. leucothrix. The medium stocking rate treatment on the steep trial showed significant shifts in relative abundance of key species, with declines in T. triandra and T. leucothrix and increases in A. semialata and the unpalatable wiregrass D. filifolius. These trends were not repeated on the flat trial, however, with T. triandra and A. semialata increasing and all other key species declining or remaining stable. On the simulation trial, species responded largely unpredictably with species abundances often fluctuating considerably over time. Microchloa caffra and A. semialata increased substantially in both the low and high stocking rate sheep-only treatments, with a concurrent decline in T. triandra in the high stocking rate but not the low. Changes in composition over time, as measured by Euclidean distance, showed that shallow soils, high stocking rates and a high proportion of sheep caused greater shifts in species composition over time than deep soils, low stocking rates or more cattle. Three treatments, the sheep-only treatments on the simulation trial and the high stocking rate on the steep trial, showed an initial rapid shift in composition over about 6 years, before stabilising in subsequent seasons. The flat trial showed no substantial shift in composition over time. This general pattern of change was confirmed by Non-Metric Multidimensional Scaling. On the simulation trial, total standing crop was influenced by stocking rate and by the proportion of sheep in most seasons. On the two-paddock trials, increasing stocking rate significantly reduced sward vigour, and vigour declined over time. Stocking rate reduced total standing crop on both trials at the end of the 2004/05 seasons and the crop of unpalatable species on the steep trial. Total palatable plants were unaffected by stocking rate on both trials. The classic Jones-Sandland model of animal performance as influenced solely by stocking rate was not supported. Sheep performance was influenced by stocking rate and the interaction of stocking rate and seasonal rainfall. There was no difference in average daily gain between treatments over time, and hence cumulative animal production per hectare increased with increasing stocking rate. Animal performance was possibly influenced by many factors beyond the scope of this study, including the effect of predator attacks on surviving animals, and resource availability such as shade and shelter and high-production patches in some paddocks and not others. Scale effects on ecology are being increasingly investigated and a meta-analysis of this type shows that, even in one research farm, slight differences in management and environment can have significant effects on plant and animal responses to grazing. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2010.

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.
