Abstract: Predominant use in the present pig breeding the breeds of European and North American origin characterized by high levels of productivity, has led to the displacement of local breeds. The study of the allele pool of pigs of the Hungarian Mangalica breed, which was on the verge of extinction, but restored by the joint efforts of various specialists up to 7,000 individuals, it is of interest in the aspect in the genetic diversity conservation of endangered and small-numbered breeds. The aim of this work was to conduct microsatellite analysis to determine the population genetic parameters of the Hungarian Mangalica breed of pigs and assessing the degree of its differentiation with respect to groups of Large White, Landrace and Duroc breeds. Analysis of using the pairwise genetic distance matrix for the FST index showed a significant differentiation of Mangalica from Large White and Duroc breeds, and at the same time, some genetic similarity with Landrace one. Thus, it has been shown that pigs of the Mangalica breed are characterized by relatively high levels of allelic and genetic diversity, and the data obtained can be used to study the parameters of the genetic diversity of small pig breeds.
