Abstract

Complete feeding makes it possible to fully use the genetic potential of animals, increase productivity and reduce feed consumption. In order to balance diets in terms of protein, it is advisable to use synthetic nitrogenous substances in feeding ruminants, since this allows releasing a significant amount of high-protein plant feeds (oilcake, meal) in diets. The article contains the results of studying the effect of feeding nitrogenous
 substances of non-protein nature on the productivity of young cattle. It was found that the use of 10-, 20- and 25% carbamide concentrate in animal diets increased the degradability of protein in compound feed, blood erythrocyte level by 6.18-7.77%,
 hemoglobin concentration by 4.8-6.2%, leukocyte content by 10.3-13.3%, platelets by 4.1-21.5%, which contributed to an increase in the average daily gain by 6.8-11.9%.
