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
Cytology and Genetics 2002, v 36, number 2, 53-59
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.
