Abstract
Each type of feeding has its own characteristics due to the specific effect of feed on the metabolism, physiological state and productivity of animals. Therefore, the aim of the study was to study carbohydrate and nitrogen metabolism at different ratios of coarse, concentrated and juicy feeds in the diet of young cattle during fattening. Feeding a silage diet with an increased level of metabolic energy contributed to an increase in the total amount of LVH by 14.5% compared with the control. The introduction of corn silage and concentrates into the diet in the experimental group contributed to a significant 12.9 mg% decrease in the breakdown of protein in the diet. The highest concentration of total amino acids in the scar fluid was observed with a silage diet with a high level of concentrated feed, 514 mg%, which is 139 mg% higher than when feeding diets with low energy saturation. With this diet, the highest average daily gain in live weight was also observed (834-1042 g). With a hay diet, the concentration of total amino acids in the sample of scar fluid was 408-505 mg% for both groups of animals. The average daily gains in these groups were 730-897 g.
