This paper shows the results of introducing the amino acids lysine concentrate and d1 - methionine, as well as the antibiotic Bacitracin, into the calves [[CHECK_SINGLEQUOT_ENT]] diet. Experimentally, the effect of meat components on the average daily weight gain; the digestibility of nutrients received from the feed; the average daily use of nitrogen, calcium, phosphorus and sulfur; the yield of meat after slaughter; the weight of internal organs and the chemical composition of meat.
