Association between polymorphism in bovine PRKAG3 gene and milk production traits

摘要

The aim of the conducted study was to evaluate correlation between genotypes and PRKAG3 compound genotypes and milk production traits (yield of milk, milk fat and milk protein, and protein and fat content in milk). The study covered a herd of 180 Jersey cows. PCR-RFLP method was used for genotyping. The frequencies of alleles that occur mostly and combined genotypes were as follows: T1526G G - 0. 57, G1609A G - 0. 92 and for T1526G/G1609A TG/GG - 0. 54. The results obtained in the study demonstrated the correlation between analyzed genotypes and selected milk production straits; however they are not statistically significant.
