Abstract
Studies on the regulation of the level of feeding of young animals in the post-embryonic period are presented. The effect of different levels of feeding on the growth rate, development, meat productivity, formation of meatiness and the ratio of the most important tissues in the carcass of young Black-and- White breed of cattle at different age periods has been established. The scheme of young animals rearing was as follows: Group 1 - increased level of feeding until 14 months of age, Group 1 (a) - rearing the young animals until 8 months in the same manner as in Group 1 (increased level of feeding), from 8 to 14 months - maintenance on medium farm feed; Group 2 - medium farm feed until 14 months, Group 2 (a) - until 8 months - medium farm (medium) feeding, from 8 to 14 months - increased level of feeding. For 14 months of rearing, 2114,8 EFU were spent per head in group 1, 1888,1 in group 2 (a), 1919,0 in group 1 (a), 1692,3 EFU in group 2; for 18 months of rearing: 3673,2 in group 1, 3345,6 in group 2 (a), 3397,4 in group 1 (a), 3240,0 EFU in group 2. Group 1 youngsters on improved feed had an average daily gain of 837 g for the whole period, which was 124, 161 and 170 g (p> 0.999) more than Group 2 (a), Group 1 (a) and Group 2 youngsters, respectively. At a high level of feeding young cattle for meat, a sharp increase in meat productivity and improved meat quality was noted. At the same time, the cost of feed for the products produced decreased and the economic efficiency of livestock breeding increased. The level of feeding has a differential effect on the development of individual organs and tissues.
