PIGS GENOTYPING BY PRKAG3 AND RYR1 GENES AND STUDY OF THEIR POLYMORPHISM

Abstract

Genotyping of pigs by PRKAG3 and RYR1 genes by PCR-RFLP method. The object of research were pigs of the following breeds: Belarusian Large White (BLW), Belarusian Meat (BM); Landrace (L), Duroc (D), Yorkshire (Y), bred in the breeding and hybrid centers of the republic. At molecular and genetic testing polymorphism of PRKAG3 and RYR1 genes was determined with animals of different breeds and sex and age groups (boars producers, sows and young animals at fattening), represented by alleles PRKAG3I, PRKAG3V и RYR1N, RYR1n, and genotypes PRKAG3VV, PRKAG3VI, PRKAG3II, RYR1NN, RYR1Nn were identified. It was found that averagely for all the breeds studied the highest concentration of the preferred PRK-AG3II genotype was observed in Landrace breed animals - 21,05 %, and the lowest - in animals of Belarusian Large White breed (5,51 %). In general, the concentration of preferred allele PRKAG3I in the breeds studied was low and averaged 0,24-0,50. By RYR1 gene averagelyby breeds the frequency of occurrence of animals with RYR1NN genotype, free of mutations, was 90,23-100 %, and carriers of the mutant gene RYR1Nn - 5,45-9,77 %.
