Gene polymorphism butterfat cattle

DGAT gene used in the biosynthesis of lipids and associated with butterfat cows. In a herd of animals found the largest proportion in the genotype frequency of АК. Heifers and high yielding cows was no significant difference between the observed and expected genotype АА, АК, КК (χ 2 = 0,85 and 2,66), that indicates no shift genetic equilibrium. While in fresh cows is a significant shift towards the genotype АК (χ 2 = 7,82, Р
