Rationing of urea concentrate in diets young cattle

Abstract
Feeding 30% of carbamide concentrate from the mass of compound feed to young cattle led to an increase in microbiological and enzymatic processes, which contributed to an increase in the cleavage of compound feed protein, which was 84% after 24 hours.
In the cicatricial fluid of the experimental young animals, a pH shift to the neutral side by 4.1-7.8% was noted, and when 25 and 30% of the studied feed were included in the diet, the difference turned out to be significant. An increase in the amount of protein nitrogen and infusoria in the scar fluid of young animals consuming 10, 20 and 25% of urea concentrate was also found.
With the introduction of carbamide in the blood of young animals of the experimental groups, the level of erythrocytes increased by 6.18-7.77%, the concentration of hemoglobin in the blood of animals of groups I-IV was higher by 4.8-6.2%. There was an increase in the content of leukocytes in the blood of animals of all experimental groups by 10.3-13.3%, platelets – by 4.1-21.5%, which contributed to an increase in the average daily increase by 6.8-11.9 percent.
