Abstract: The chemical composition analysis of average meat samples and M. longissimus dorsi testify that the greatest nutrients variability characterizes fat, the protein and mineral substances of carcasses edible part possess relative stability. In the study of qualitative structure of slaughter products the general regularity was revealed – increase of dry matter and fat contents and decrease in moisture with age. The process of fat deposition in the pulp of carcasses of compact body type genotypes was more intensive. That led to the maximum size (38,04%) of dry matter contents. Intensive accumulation of adipose tissue in compact body conformation group of bull-calves already had began with one-year-old age and to 15-month age the protein and fat ratio reached 1-0,65. At the age of 21 months tall animals were the best protein and fat ratio- they had ratio 1-0.83 instead 1-1.28 and 1-0.99 at compact and the medium contemporaries. Compact bull-calves had the highest of a forage’s protein and energy expenses into own body nutrients, the smallest had tall contemporaries.
