Abstract
Data on morphological carcass composition study in both purebred and mixed bred bull-cal-ves, obtained from crossing black-and-white cows with Aberdeen-Angus and Charolais bulls, are provided in the article. It has been discovered that the carcasses mass of bull-calves increased with age due to more intensive. Lean part growth and skeleton to a lesser degree, Bull-calves, genotype has an important influence on muscu-lar system growth. Inherited potential in musculature growth is better realized in Charolais mongrel bull-calves, the degree of muscular component being 253.6 kg at the age of 18 months, which is by 31.5% bigger than in they black-and-white herdmates. There are no big differences in carcass muscular tissue weight between Aberdeen-Angus crossbreeds and black-and-white Bull-calves. The greatest adipopexis growth by the end of the experiment is a characteristic feature of Aberdeen-Angus crossbreeds. The skeleton growth rate of young animals by comparison during the experimental period is practically the same, but with age the skeleton growth rate decreases significantly in bull-calves.
