Resumen : | The creole pigs represent 67% of the national population in Peru. They are a source of economic income in rural communities, and due to their rusticity, they are not much labor demanding. However, knowledge about its genetic diversity remains scarce. The objective of this study was to determine the population structure and genetic diversity of creole pigs from rural communities in south central Peru. Thirteen microsatellites were used to characterize 120 creole pigs from the departments of Ayacucho (57) and Apurimac (63). The samples were taken from hair follicles and ear tissue. Nine microsatellites were highly polymorphic and informative (PIC > 0.5) for both departments. The Ayacucho population had a mean number of alleles (MNA) and expected heterozygosity (HE) of 8.8 and 0.68, respectively, while in the Apurimac population, these were 8.9 and 0.71, respectively. Both populations showed in less than 50% of their loci a deviation from Hardy–Weinberg equilibrium. There was a moderate genetic structure according to the analysis of molecular variance and the FST statistics (0.06), which was corroborated by Bayesian methods. In conclusion, the genetic diversity was mostly due to the intrapopulation variance (91%). Some individuals from Ayacucho shared similar alleles with those from Apurimac. This latter result may be due to their geographic proximity and the introduction of the same new exotic breeds. This is the first research on the genetic diversity of creole pigs in south central Peru. In fact, this study could serve as a basis for conservation strategies and actions in this region. |
