GENETIC CAPPA-CASEIN POLYMORPHISM IN CATTLE
This article highlights the experimental research results on genetic cappa-casein polymorphism in cattle. Red-Steppe, Ukrainian Black-and-White and Simmental population structure was evaluated according to cappa-casein gene. Genetic and differential analysis was fulfilled. AA genotype animal percentage equals 77,1 % in the bulk of breeds. The top lactation performance was observed in the tested breeds. Red-Steppe population proved to advantage the other breeds by cappa-casein allele gene. The above-mentioned gene prevailed in the bulk of animals. Percentage equals 19 % (0,191). Complete analysis was executed by the authors. Experimental investigations of Ukrainian and foreign scientists were studied on genetic cappa-casein polymorphism in cattle. Scientific publications were analyzed for the period of the last 10 years.
