Abstract:
Genome-wide assessments of the genetic landscape of Farm Animal Genetic Resources (FAnGR) are key to developing sustainable breed improvements. Understanding the FAnGR adaptation to different environments and supporting their conservation programs from community initiative to national policymakers is very important. The objective of the study was to investigate the genetic diversity and population structure of communal indigenous goat populations from four provinces of South Africa. Communal indigenous goat populations from the Free State (FS) (n = 24), Gauteng (GP) (n = 28), Limpopo (LP) (n = 30), and North West (NW) (n = 35) provinces were genotyped using the Illumina Goats SNP50 BeadChip. An Illumina Goats SNP50 BeadChip data from commercial meat-type breeds: Boer (n = 33), Kalahari Red (n = 40), and Savanna (n = 31) was used in this study as reference populations. The Ho revealed that the genetic diversity of a population ranged between 0.39 ± 0.11 Ho in LP to 0.42 ± 0.09 Ho in NW. Analysis of molecular variance revealed variations of 3.39% (p < 0.0001) and 90.64% among and within populations, respectively. The first two Principal Component Analyses (PCAs) revealed a unique Limpopo population separated from GP, FS, and NW communal indigenous goat populations with high levels of admixture with commercial goat populations. There were unique populations of Kalahari and Savanna that were observed and admixed individuals. Marker FST (Limpopo versus commercial goat populations) revealed 442 outlier single nucleotide polymorphisms (SNPs) across all chromosomes, and the SNP with the highest FST value (FST = 0.72; chromosome 8) was located on the UHRF2 gene. Population differentiation tests (PCAdapt) revealed PC2 as optimal and five outlier SNPs were detected on chromosomes 10, 15, 20, and 21. The study revealed that the SNPs identified by the first two principal components show high FST values in LP communal goat populations and allowed us to identify candidate genes which can be used in the development of breed selection programs to improve this unique LP population and other communal goat population of FS, GP, and NW, and find genetic factors contributing to the adaptation to harsh environments. Effective management and utilization of South African communal indigenous goat populations is important, and effort should be made to maintain unique genetic resources for conservation.

Abstract:
Context Indigenous cattle breeds represent an important genetic resource for livelihood of communal-area inhabitants. Indigenous breeds have the ability to withstand harsh climatic conditions, can adapt genetically to poor-quality forages and are resistant to parasites and diseases. These unique traits possessed by indigenous breeds are under threat because of unrestrained crossing with exotic commercial breeds, and this can lead to total loss of a breed. Aims The study was conducted to assess the genetic diversity and population structure of South African non-descript communal beef cattle populations by using 25 microsatellite markers. Methods Unrelated and non-descript animals (n = 150) were sampled from communal areas from five (5) provinces of South Africa, namely, Eastern Cape, KwaZulu–Natal, Limpopo, Mpumalanga and the North West, with 30 samples per breed taken. Six (6) known cattle breeds (n = 180) were used as a reference population. This included Angus, Afrikaner, Bonsmara, Brahman, Drakensberger and the Nguni, with 30 samples per breed. Key results High level of genetic diversity was found across the five non-descript populations, with an average heterozygosity of 75%. The Limpopo population was found to be the most diverse population, with the highest average number of alleles (8.5) and heterozygosity (ranging between observed heterozygosity of 70% and expected heterozygosity of 79%). STRUCTURE software assigned populations (2 ≤ K ≤ 20), with the most probable cluster being at K = 7. The Eastern Cape, KwaZulu–Natal and Limpopo populations had genetic material similar to those possessed by the Nguni and Bonsmara reference populations. Conclusions Results from the study showed that most genetic differentiation occurred within populations rather than among populations, and this might be due to the fact that there is no selection for or against any specific production trait expressed in the populations. Implications The obtained information will serve as a baseline for the development and implementation of sound breeding programs that will assist in controlling the gene flow, so as to lower the possible genetic dilution of the currently available genetic material.

Abstract:
SummaryThere are mainly three locally developed meat type goat breeds in South Africa namely the South African Boer goat, the Savanna and the Kalahari Red. In order to maintain the characteristics of these breeds and to ensure that their unique traits are not lost through continuous selection and cross-breeding, it has become important to revisit current breed standards and introduce genetic characterization to obtain genetic diversity parameters. Both the Boer goat and Savanna breeds have established breeders associations while a breeders club was founded for the Kalahari Red goats. These associations have set breed standards and the breeds' morphometric traits have recently been described. The differences in morphometric traits among the breeds are fairly insignificant. Preliminary data on genetic diversity report heterozygosity values above 50% for each of the three breeds and they can be distinguished as separate breeds based on genotyping results with eighteen ISAG recommended microsatellite markers. There is however a need for a genetic characterization of both meat type and indigenous goats to ensure sufficient diversity within the breeds for long term conservation of the unique genetic resource.

Abstract:
SummaryThe paper analyses the importance of breed conservation in South Africa by means of added value through a number of species. This principle was applied to some of Southern Africa populations: Nguni cattle, indigenous pigs, indigenous sheep landraces including fat-tails (Pedi, Damara, Zulu, Afrikaner) and fat-rumped breeds (Persian) as well as the improved Boer goat. The latter is an example of what can be achieved by selecting an indigenous breed for a specific purpose.For each breed, possible alternative uses are explained by analysing their characters. For the Nguni cattle (very well adapted to local conditions) a premium is paid for hides with minimal tick damage as these are used for car upholstery, an important added value. Beef quality and easy calving are also relevant factors that are important when crossing the Nguni with European breeds.Indigenous sheep landraces are often used to develop hardy composites and this helps their conservation, while the Boer goat is in demand in many countries for meat-production and has been exported world-wide; this is probably the only selected meat-goat in the world.Indigenous pig breeds are capable of generating a good income and are satisfactory alternatives to modern breeds.

Abstract. Goats play a variety of roles all around the globe due to their capability to acclimatize different environmental conditions quite quickly since they have been regarded as one of the first sets of animals domesticated by the human. Even though domestic goats harbor precious genetic materials, research funding among developing countries is a major drawback for thorough study on them. Therefore, microsatellite markers seem to be affordable and informative. Genotypic data from different goat breeds across five countries (Nigeria, South Africa, Pakistan, France and Spain) was generated using eleven microsatellite markers for a comparative study in order to evaluate the usefulness of the available data for genetic characterization and identify the shortcomings of meta-analyses for combined data. The mean number of alleles (MNA) per population range from 6.44±2.83 alleles for Spanish to 10.25±0.96 for Pakistani goats, with an overall mean of 13.55±7.28. Observed heterozygosity (Ho) ranges from 0.61±0.02 to 0.83±0.01 for Spanish goats and Pakistani goats, respectively with an overall mean of 0.65. Ho of the markers used ranged from 0.569 (INRA5) to 0.793 (MM12). Highest and least polymorphic information content (PIC) was observed in loci MM12 (0.925) and MAF209 (0.489), respectively. All the populations showed significant change from Hardy-Weinberg equilibrium (P>0.05) indicating a low level of inbreeding. The genetic distance of each country’s goat populations ranged from 0.151 to 4.245. The highest genetic distance (4.245) was observed between Spanish and Pakistani goats while the lowest were observed between Spanish and French goats. Spanish and French goats are from a common ancestor while South African, Nigerian and Pakistani goats came from another ancestor or cluster. A lot of genetic admixture in the Nigerian ecotypes has been observed whereas France and Saudi Arabian breeds have been subjected to high amount of selection pressure.

Abstract:
Sorghum farming group in South Africa is divided into the smallholder and business ranchers attributable to the distinctions in cultivar sizes, utility creation and production strategies. Sorghum is utilized primarily for sustenance and refreshments in Ga-Masemola (GM) town. Smallholder sorghum farmers in the town utilize some portion of their wage for recreation, goat and cows' compost are utilized as manures to enhance soil fruitfulness and increment sorghum yield, they rely upon precipitation water for the water system and they have no entrance to expansion administrations. The study distinguish and depict the socioeconomic characteristics of smallholder sorghum farmers in Ga-Masemola town; it looks at the causes of technical efficiency among smallholder sorghum ranchers in the town, and it recognizes and portrays difficulties confronted by smallholder sorghum farmers in the town. Essential information was gathered utilizing organized surveys and an example size of 48 smallholder sorghum farmers in the town was chosen. Cobb Douglas model was utilized to analyze the information or data gotten.The socioeconomic characteristics of smallholder sorghum farmers were:farming experience, age, sexual orientation, instructive level and family unit measure. The study indicates that the determinants of technical efficiency among smallholder sorghum farmers in Ga-Masemola town that were observed to be huge are the measure of land dedicated and the amount of seeds utilized. Farmers are confronting difficulties, for example, sicknesses, low capital, pests, separation to the homestead, absence of water and atmosphere (i.e. climate) changes.The study suggested and recommended that smallholder sorghum farmers in Ga-Masemola (GM) town require arable land to expand their production; they additionally require agriculture extension officers for training and spreading or disseminating information about inputs allocation. Besides, the smallholder farmers should be encouraged to utilize enhanced seeds varieties in order to expand their technical efficiency.

Abstract:
The aim of this study was to design a case study where a number of management accounting evaluation techniques, namely performance measurement (short-term focus), capital investment evaluation (long-term focus) and risk, have been identified to compare the financial results of different scenarios between Boer goat, mutton breeds and beef cattle farming. The contribution of the study is that it simplifies the decision-making regarding the choice between the types of red meat farming used for different scenarios, namely farm size and available capital. Compliant software that have been developed, allow the user to compile unique scenarios and make decisions according to that. The value of this should be determined by taking into account that there are, as for other livestock types in South Africa, no readily available market indicators for the Boer goat currently. This deficiency leads to price uncertainty that makes it difficult to determine the value of the Boer goat industry.

Abstract:
A genetic study of four commercial goat breeds in South Africa was performed using microsatellite markers. The commercial breeds included the Boer goat, Savanna, Kalahari Red and the Angora goat. Indigenous goat populations from Delftzijl and Groblersdal were also included in this study. Seventeen microsatellite markers were tested to determine the genetic variation. Genetic variation within the breeds were relatively high with heterozygosity values ranging from 57% for the Boer goat, 68% for the Kalahari Red, 69% for the Savanna goats and 70% for the Angora goats. First values indicated that the Savanna and Boer goat are genetically the closest (0.114), while the Kalahari Red and Boer goat are the least related (0.237). Phenotypic measurements included height, length, depth, heart girth, pelvic length and width for a phenotypic description. Significant differences were observed in the phenotypic measurements among all the breeds. The genetic and phenotypic differences indicate that these goats can be distinguished as different breeds. Results of this study contribute genotypic information of the commercial goats in South Africa. Copyright

Abstract:
A pig genetic resources study was conducted in five municipalities of Sekhukhune with the aim of characterising pig genetic resources in communal farming systems. A total of 52 pig farmers were interviewed using a structured questionnaire instrument. Of the 52 farmers 65 percent were subsistence, 27 percent back-yard and 8 percent emerging farmers. The primary data collected included demography, production practices, herd structure, feeds and feeding, breeding practices, marketing, and conservation methods. Two indigenous pig farmers and one exotic pig farmers were selected for purpose of measuring growth and other linear traits of piglets over a period of two months. Four hundred and nine (409) pigs were used for body measurements of which 124 were from emerging farms, 71 from subsistence and 206 from back-yard farms. Data was analysed using SAS Package (SAS, Version 9.3). Demographic representation of farmers showed 79 percent of farmers being males, 85 percent married. With 50 percent between the ages of 55-64; 60 percent owning the farms and 83 percent Northern Sotho speaking farms. The majority of farmers (39 percent) had secondary education with 81 percent trained in production and over eight years of farming experience. The objective of farmers raising pigs was mainly for selling at a frequency of 60 percent. Over 70 percent of the farmers had a good grasp of controlling internal and external parasites. However, over 80 percent of the farmers did not vaccinate or get advice from extension officers. When comparing the production systems, there was no variation in the number of young pigs produced. Only 13 percent of the emerging farmers and eight percent in back-yard had proper housing. Only 10 percent of the farmers had financial assistance. That led to only 10 percent of the farmers able to feed complete rations to their animals. Cross breeding has been practiced within communal areas by over 75 percent of the farmers. Over 15 percent bought boars from commercial farmers. This practice enabled them to sell their piglets to private buyers at 50-60 kg at an average price of R500 – R1000. Though the value of indigenous breeds was rated high by over 63 percent the size and price compelled them to cross-breed. An establishment of an indigenous breeding program is highly recommended.

The Boer goat (Capra hircus) is one of the most desirable goat breeds for meat production. The impact of cryopreservation on the viability of its semen depends on the extenders, freezing and thawing methods. This study evaluated the effects on sperm viability in Boer goat semen extended using Bioxcell, Biladyl and Ham’s F10, and frozen in semen straws placed on a rack at 4, 5, 6 or 7 cm above the surface of liquid nitrogen. After storage in liquid nitrogen for 7 days, the frozen semen was thawed at 37 oC for 30 seconds or 90 oC for 5 seconds. Samples of sperm were also frozen to -196 oC in a programmable freezer, as the control regime for the freezing treatments. Sperm morphology, motility and viability were evaluated using the computer aided sperm analysis (CASA) system in a randomised design in which the treatments were in a 3 (extender) X 5 (freezing regime) and X 2 (thawing regime) factorial arrangement. The extenders Bioxcell and Biladyl were affected in the total motility, progressive motility and static (P<0.01), the motility was overall maintained only in straws placed at 5 cm above the liquid nitrogen level, with significant difference for the interaction extender X freezing regime in the total motility (p<0.01), non-progressive motility (p<0.05) and progressive motility (p<0.01), the 37 oC for 30 sec thawing regime had significantly more (P<0.05) in cut-head spermatozoa. Ham’s F10 extender had significantly lower normal spermatozoa (P<0.05) compare to Biladyl and Bioxcell extenders. In conclusion, the extender type, freezing and thawing regime were important factors for consideration in goat semen

Dissertation (MSc(Agriculture)
The main objective of the study was to analyze the economic viability and sustainability of the leasing system in the development of dairy goat’s keepers group in Ga-Mampa, Mafefe rural community. Mafefe is one of the rural communities where dairy goat keeping is given little or no care by the dairy goat keepers. Through an action research process implemented within the community by the Center for Rural Community Empowerment (CRCE/University of Limpopo: Turfloop Campus), community members became interested in developing dairy goat keeping, which was very dubious to the community members as it was their first time to hear about goats bred for milk production. In Limpopo Province, goats are the most common livestock among communal farmers and yet they do not make a significant contribution to the economy of the place, let alone improve income of the households who keep dairy goats. The purpose of the study, therefore, was to find ways to transform the current subsistence system of producing indigenous goats by households in Ga-Mampa Mafefe (Capricorn District (CD)) in the Limpopo Province of South Africa into a viable system of producing, processing and marketing both dairy goats and their byproducts through formal markets. The study attempts to find out as to how a commodity group manages capital through a leasing system to sustainably insure that its members can access a technical innovation: dairy goat keeping. This study also looks at how leasing contributes to the development of the dairy goat project, the community and the development of individual members of the project. The Net Present Value (NPV) and Benefit Cost Ratio (BCR) criteria were used to evaluate the economic viability of the leasing system towards the development of dairy goats. The results indicate that the NPV in this study is greater than zero, therefore the project is considered to be economically viable and sustainable, and also the BCR is greater than one indicating that the project is still profitable and hence acceptable. According to the findings from the analytical techniques, production of dairy goats through the leasing system would be profitable to dairy goat keepers. vi A sensitivity analysis to changes in benefits and costs of inputs was conducted. This found the above project proposal to be viable, even when benefits are reduced by 20%. The project proposal was still viable when the cost of inputs was inflated by 20%. In both cases, the benefit cost ratio is greater than one. Also the combined effect of reducing the benefit by 20% and inflating cots by 20% would result in positive Net Present Value (NPV). Results from a survey carried out further show the possibility and viability of producing satisfactory levels of milk from dairy goats in Limpopo Province.
