Breeding highly productive black-pied cattle using the Holstein breed genotype has shown great results. The Holstein breedis characterized by high productivity and most fully meets the requirements of modern milk production technologies. Thebreeding and productive qualities of cows are improved by various methods, including intra-linear and inter-linear selection. Thegenetic progress resulting from such breeding methods is undeniable. When studying the genetic characteristics of each herd,such an important indicator of breeding as heritability is rarely taken into account, and data on the dependencies between breedingtraits are often not used. The use of animals with valuable genotypes requires a new attitude in the study of economiccharacteristics. The integrated use of genetic methods will significantly increase the rate of improvement of breeding qualities,which is relevant at the current moment.
