Based on the results of the analysis of the relationship between the DGAT1 gene polymorphism and economically valuable traits, it was concluded that animals with the DGAT1KK genotype have the highest milk yield and fat content. When analyzing the relationship of CSN3 gene polymorphism with milk productivity, it was found that higher rates are characteristic of mothers cows with a homozygous CSN3BB genotype. Animals of this group have an advantage, in comparison with the AB and AA genotypes, in milk yield, protein content, mass yield of fat and protein. When studying the data of the relationship between the LGB gene polymorphism and economically valuable traits, it was concluded that animals with the homozygous LGBBB genotype have the highest milk yield, fat, protein content, mass fat and protein yield.
