Genetic Polymorphism of the Blood and Milk Enzymes and Proteins and Their Association with the Economically Valuable Traits of Black-and-White Cattle of the Western Region of Ukraine

Siratskyy I. Z., Fedorovych E. I.

The structure of genetic polymorphism of the blood and milk proteins and blood enzymes was studied. It was shown that in the Western region of Ukraine Black-and-White breed cattle had seven phenotypes of transferrin, one phenotype of hemoglobin, three phenotypes of amylase, five phenotypes of alkaline phosphatase, ceruloplasmine, β–lactoglobuline, and αsi-caseine, and three phenotypes of β-caseine. The effects of homo-and heterozygous levels on the heifer growth, milk production and fertility of cows were found. Complex analysis of polymorphism of blood and milk ferments and proteins gives possibility to find a closer association of genetic tests with growth, milk production, and fertility of animals of Black-and-White breed.
