Abstract
The article describes the selection of red motley Holstein bulls by genotype imported from Germany to the state enterprise "Uznaslchilik" and their use in breeding practices, which are also characterized by breeding and productivity qualities typical of black motley types. In the study of world breeding practices, new high-yielding herds are being formed by crossing dairy red breeds with red motley Holstein breed bull-improvers. The red motley Holstein breed is also recognized in our country as an improver and is being used in artificial insemination. KEYWORDS: Red motley Holstein breed, breeding and productivity, artificial insemination, crossbreeding, selection and pairing, fertile, individual, genotype, breeding, total merit index, farm useful traits.
