Influence of the kappa casein genotype on the technological properties of cow milk of Simmental and Alatau breeds.

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.
