The main objective of dairy farming is to obtain highly productive animals that produce milk with high protein content and have good technological properties. Currently, with the development of molecular genetics and molecular biology, it is possible to identify genes directly or indirectly associated with the milk production of animals. The identification of variants of such genes that are preferable from the standpoint of selection will allow, apart from the conventional selection of animals, to perform selection at the level of deoxyribonucleic acid technologies, i.e. according to genotype. The paper includes the study of milk productivity indicators and physicochemical quality indicators of milk from cows of Simmental and Alatau breeds by loci of the kappa casein gene, and also determines the cheese suitability and technological properties of milk of cows of Simmental and Alatau breeds with different genotypic affiliations for kappa casein for the production of semi-hard cheeses. The determination of polymorphism by the kappa casein gene was carried out with the use of the polymerase chain reaction method for genotyping of the major milk proteins of kappa casein gene. In a comparative aspect, the interrelation of genotypes with milk productivity was studied, the frequencies of allelic polymorphism of cows of Simmental and Alatau breeds in the Republic of Kazakhstan were identified, the nature of milk productivity was determined for each genotype. Scientifically based data on the assessment of biological value, technological properties, cheese suitability of milk of cows of Simmental and Alatau breeds are obtained.
