Abstract. This article presents the results of creating experimental conditions for replenishing the missing nutrients in the body to study the effect of monocarbamide monocalcium phosphate (MCMCP) and its combination with microelements of copper, cobalt, iodine on metabolism, cicatricial digestion and sheep productivity. The work was carried out from June 20 to July 30, 2016. The subject of the study were 15 ewes, divided into three equal groups. The experimental and control sheep were examined before and every 15 days of the experiment, the rations were analyzed, the body weight was determined. Feeding monocarbamide monocalcium phosphate (MCMCP) (10 g) and its combination with microelements (MCMCP – 10 g, copper sulfate –10 mg, cobalt chloride – 2 mg, iodine –0.3 mg) for 40 days normalizes cicatricial digestion and metabolic processes, increases the average daily increase in the mass of sheep by 19.8 and 23 %, respectively (compared with the control ones). Clinical and physiological parameters in all animals during the experiment were within the norm, but the experimental sheep from the control differed in their activity, good reaction to external stimuli, and better feed intake. The pronounced influence of additives on the exchange was in the sheep of the second group. The mechanism of the positive effect of this additive is associated with the improvement of cicatricial digestion as a result of an increase in infusorians in the prednagus, the synthesis of them by the LZK, vitamin B12 and protein from non-protein nitrogen, with an increase in digestibility of nutrients in the feed and activation of metabolic processes. More pronounced on the organism of sheep affects monocarbamide monocalcium phosphate (MCMCP) in combination with microelements of copper, cobalt and iodine.
