Summary
The objective of this study was to determine the intra-and inter genetic diversities of four different goat populations in Sudan namely Desert and Tagger (indigenous) and South African Boer and Kalahari Red (introduced). A total 120 DNA samples were genotyped using five microsatellites markers (BMS2508, BM143, OarAE101, OarAE129, OarHH55) which are recommended by Food and Agriculture Organization (FAO) of the United Nations and International Society for Animal Genetics (ISAG). The pooled average range of the genetic variability parameters for the four populations studied were: Observed allele numbers (Na), Effective number of alleles (Ne), Observed heterozygosity (Ho), Expected heterozygosity (He), Shannon’s Index (I), were: 4.2 (Kalahari Red) to 8.4 (Tagger)., 2.2 (Kalahari Red) to 4.3 (Tagger)., 0.438 (Kalahari Red) to 0.592 (Tagger)., 0.538 (Kalahari Red) to 0.751 (Tagger)., 0.992 (Kalahari Red) to 1.533 (Tagger), respectively. The polymorphic information content (PIC) for all the markers used scored 100%, indicating that all the markers used were appropriate for mapping the diversity of the populations studied. Within populations differentiation was considerable as indicated by the Fisestimate of 0.031 for Boer goats and 0.311 for Desert goats. The results reflect that the populations studied contain a valuable and substantial genetic diversity and there is a good scope for bringing effective sustainable conservation and genetic improvement.
