EFFECT OF THE POLYMORPHIC COMPOSITE FORMS OF BETA-LACTOGLOBULIN ON THE MILK YIELD AND CHEMICAL COMPOSITION IN MAXIMUM LACTATION

EFFECT OF THE POLYMORPHIC COMPOSITE FORMS OF BETA-LACTOGLOBULIN ON THE MILK YIELD AND CHEMICAL COMPOSITION IN MAXIMUM LACTATION

On the basis of polymorphism in beta-lactoglobulin gene, a genetic structure of 155 cows bred in the Kujavian- Pomeranian voivodeship was detemined. Genotypes marking was conducted using the PCR-RFLP method. The results of the analysis, as regards polymorphism in beta-lactoglobulin gene, indicate th...
