Abstract
The authors conducted a comparative analysis of the growth energy indicators and the dynamics of the live weight of young Kalmyk breed at different levels of feeding during the suckling period. It was shown that during the entire growing period, the consumption of metabolic energy in experienced bulls was 4000 MJ and 50 kg of digestible protein more than in peers of the control group. Additional feeding of suckling calves provided superiority in average daily growth in bulls by 70 g, and in heifers by 38 g per head per day. Heifers of all groups could be used in reproduction, since their live weight corresponded to 75% of the live weight of full-aged cows. From the bulls of the experimental group, having higher live weight indicators and a lower cost of 1 kg of gain than the peers of the control group, but with the same realizable cost of 1 kg of live weight,56.1% more profit was obtained and 5.3% higher profitability. During the experimental period, the animals of all groups did not have a high growth rate: at the age of 17 months, the bulls reached slaughter conditions with live weight indicators of more than 400 kg, with a significant superiority in favor of the animals of the experimental group. At the same time, a positive dependence of the growth energy of young animals, their live weight and the selling price with cost recovery and profitability has been established.
