Liyeweight gain of heifers with different genotypes in the genes of kappa-casein and diacylglycerol of O-acyltransferase

The change in the average daily and absolute increase in liveweight in the periods from birth to 15 months of age in black-and-white heifers with different genotype for kappa-casein and diacyl-glycerol O-acyltransferase was studied. It was found, that according to most indicators of the average daily and absolute increase in live weight, the heifers with the CSN3AB, DGATlAK. DGA11KK genotype had an advantage over the animals of other experimental groups.
