Amino acids are structural components of enzymes, hormones, pigments and other biologically active substances that regulate digestive and metabolic processes. The objective of the study was to investigate the effect of NCG - N - carbamyl glutamate feed additive on the amino acid composition of the blood of fattened bulls. Six-month-old fattened bulls were divided into two similar groups of five animals each. The feed additive was fed to six-, seven-, eight- and nine-month-old bulls as part of a grain concentrate mixture at a dose of 5 grams per animal per day. The feeding period was 120 days. The feeding ration in both groups was identical. The experimental period was winter stall housing. The animals were tethered and given free water. Results were recorded starting at seven months of age. Blood was collected monthly from the jugular vein before feeding. The experiment revealed a statistically significant increase in the concentration of essential amino acids in the blood serum of the experimental group from 7.40 to 22.22% (p < 0.05) and nonessential amino acids from 7.40 to 17.30% (p < 0.05) compared to the control group during this period. The supplement contributed to the optimization of the species composition and enzymatic activity of the rumen microflora, as well as to an increase in the efficiency of protein proteolysis to amino acids with their subsequent absorption into the systemic circulation.
