Evaluation of allele pools particularity of certain pig breeds

Abstract

Aim. To evaluate particularities of immunogenetic structure of certain pig breeds, which are breeded in Ukraine. Methods. Studies were conducted at the main farms for pig breeding of: Large White, Large Black, Mirgorodska and Duroc. Red blood cell antigens have been identified, immunogenetic parameters and differentiation of populations allele pool have been studied. Results. This article highlights objective evaluation of their genetic variability degree and defines differentiation of populations allele pool by genetic distances and their immunogenetic similarity. Conclusions. Particularity in assayed pigs populations characterizes by certain differences in relations of appropriate alleles. Pairwise comparison of breeds by genetic distances revealed the biggest similarity of Large White and Mirgorodska breeds by alleles of nine blood groups systems.

Keywords: immunogenetic markers, differentiation, gene pool, pig breeds.
