The use of the technology with feeding calves for beef based on a high-concentration type of feeding (59-61% of the energy nutritional value) on Aberdeen-Angus calves led to an increase in the meat productivity of animals in comparison with the control group kept under the traditional feeding system adopted for beef cattle "cow-calf". At the same time, during the period of growing and fattening (3-12 months), the average daily gain in live weight of bulls in the experimental group was 1359 g, which was 30% higher than these indicators in the control group, and was accompanied by an increase in the absolute gain in live weight of young animals by 81.4 kg as well as slaughter yield by 3.6%. The use of the technology with feeding calves for beef based on the high-concentration type of feeding (65- 70% of the energy nutritional value) on Holstein calves led to an increase in the meat productivity of animals in comparison with the control group kept under the traditional feeding system adopted for young dairy cattle with a level of concentrates in the diets more than 50%. At the same time, for the period of growing and fattening (3-12 months), the average daily gain in live weight of bulls in the experimental group was 1359 g, which was 47% higher than these indicators in the control group, and was accompanied by an increase in the absolute gain in live weight of young animals by 120 kg, as well as slaughter yield by 3.1%.
