Influence of a complex of nitrogen-containing additives on the meat productivity of cattle

Abstract

Scientific and economic experience was conducted to study the effectiveness of the use of nitrogen-containing additive Minogen as a source of protein in feeding young cattle. The experiment was carried out on two groups of Kalmyk bulls with 10 heads in each initial live weight of 310.6-313.2 kg for 90 days. The differences in feeding consisted in the fact that 60 g of nitrogen-containing feed additive Menogen was included in the grain forage of young animals of group II.

Studies have found that in terms of growth energy, the bulls of the experimental group were superior to the animals of the control group, had a higher growth rate. According to the average daily increase, the animals receiving the supplement had an advantage of 189 g during the entire fattening period. At the end of fattening, the difference in relative growth was 1.8% in favor of the animals of the experimental group. The carcass weight of the bulls of the experimental group was 4.1% higher than that of the control animals. Accordingly, the carcass yield was 53.8 and 53.1%. The profitability of beef production using the Menogen feed additive in the experimental group was 53.2% and was 9.4% higher than in the control group.
