Аbstraсt: The effect of cobalt acetic acid on the indicators of cicatricial digestion and protein metabolism in bulls aged 3-6 months was studied. The replacement of cobalt sulphate with cobalt acetic acid in the compound feed did not have a significant effect on the processes of scar digestion. All indicators were within the limits of physiological norms. The animals of the experimental group showed a tendency to decrease the ammonia content in the scar fluid by 4.2%. The use of concentrates with the addition of organic cobalt compounds helps to increase the productivity of animals and the efficiency of feed use. The average daily increase in live weight in the animals of the experimental group increased by 2.7%-4.5%. The increase in productivity had a positive effect on the efficiency of the transformation of nutrients in the diet into
products. Thus, feed costs for products decreased by 2.8%.
