Abstract

In cows of the Belarusian black-motley breed using PCR-RFLP method set gene polymorphism of beta-lactoglobulin. Identified genotypes LGBAA, LGBAВ and LGBВВ. Calculated frequency of alleles and genotypes in the gene beta-lactoglobulin. Studied milk productivity (yield of milk, fat and protein content of the milk, the amount of milk fat and milk protein) in animals with different genotypes of beta-lactoglobulin. Established the superiority of the cows with genotype LGBВВ the main indicators of milk production.
