BASIC BREEDING AND GENETIC PARAMETERS OF MILK QUALITY IN DIFFERENT CATTLE BREEDS

The article presents the results of studies aimed at determining the effect of the main genetic and paratypic factors on the quality indicators of milk in order to develop scientifically grounded proposals for improving the quality of produced products. Among the studied livestock, 41.7-65.5% of animals have the desired genotype, heterozygous animals with one desired A2 allele – 30.0-45.8% and homozygous and heterozygous animals with two undesirable A1, B alleles from 4.4 to 15.0%, which is of practical importance for targeted breeding work in terms of the production of raw milk with specified technological properties for cheese making and other processing areas, which will increase the competitiveness of the products and their safety.
