METHOD FOR DETECTING GENETIC POTENTIAL BY MILK QUALITY IN CATTLE

摘要

FIELD: agricultural biotechnology, selection of farm animals.;SUBSTANCE: genetic potential in cattle should be evaluated due to DNA-testing animals' genotypes by RsaI-marker of prolactin gene and AluI-marker of growth hormone gene and detecting conjugated genotypes by the loci of prolactin and growth hormone that detect either increased or decreased content of fat and protein in milk according to the elaborated list of genotypes. The innovation enables to carry out early selection of perspective heifers for dairy animal science and conclude upon the purposefulness of applying stud bulls before the appearance of lactating offspring in them and, also, match the pairs in selection work on improving dairy breeds.;EFFECT: higher accuracy of detection.;1 ex, 6 tbl
