Abstract (English):
Dairy cattle products are the main source of year-round income for regional agricultural enterprises from the sale of milk and dairy products. Today, the milk production system is a complex biotechnological process, and a modern dairy complex is an engineering-biological structure. In this regard, there was a need to improve its milk productivity, especially milk yield and milk fat content. To achieve this goal, breeders use genotyping to determine the genetic potential of animals and identify first-calf heifers with desirable alleles for use in breeding

Keywords:
DNA, gene, TG5, thyroglobulin, milk productivity, first heifers, Holstein breed
