β-LACTOGLOBULIN GENE POLYMORPHISM IN HOLSTEIN-FRIESIAN CATTLE REARED IN BULGARIA: A POPULATION GENETIC PERSPECTIVE
β-lactoglobulin (LGB) is a major whey protein in ruminant milk. Its genetic polymorphism is of great interest due to its influence on the qualitative and technological properties of milk. The experiment was con-ducted within a small Holstein-Friesian population reared at the Academic Technological Complex of Trakia Uni...
