Abstract

The indigenous sheep breeds of South Africa are of importance than any other livestock within the country and they are subdivided into different breed’s types which differ based on their geographical origins of origin. These types are threatened with extinction due to terminal crossbreeding effect. An understanding of the genetic diversity of types is essential prior to conservation and implementation for proper breeding programmes. 96 South African Ovine samples, comprising of 25 Pedi, 25 Namaqua, 25 Swazi and 21 Damara were genotyped using the Ovine50KSNP BeadChip assay. Genome Studio (Illumina) software was used to make the genotypes from the raw genotypic data. Genotypic data were subjected to quality control (QC) measures using PLINK software. After QC of 54 241SNPs, 48 429 SNPs remained for analysis (MAF >0.05). The outcomes of this study delivered valuable understanding regarding genetic variation within and among four indigenous sheep breeds. Keywords: nguni sheep, breeding programmes, crossbreeding.
