At present, increasing the effectiveness of breeding work cannot be achieved by traditional methods of assessing breeding value. In this regard, the use of DNA technology opens up new opportunities in determining hereditary information about the animal, which will allow for an assessment, without waiting for its own productivity. Therefore, the aim of our studies was to search for associative links of polymorphism of the SCD1 gene with dairy productivity. The genetic characteristic of the population structure was established, with the frequency distribution corresponding to 0.54 (C) and 0.46 (T), in the genotypes polymorphism the distribution was 218 with the CC genotype (20.2%), 739 with the CT genotype (68.6%) and 121 heads with TT genotype (11.2%). The conducted studies show that cows with the SCDTT genotype have a significant superiority in milk of milk in the dynamics of the first three lactations, as well as high protein content in milk. However, the yield of milk fat was higher in animals with the genotype SCD1CC
