Abstract. Dairy cattle breeding is the leading branch of animal husbandry. For a more complete provision of population with milk and dairy products is the task of increasing the productivity of animals. Perhaps this is due to the optimization of feeding. The use of new types of fodder, balanced feeding allows to increase the yield while maintaining the physiological status and productive longevity of cows. The purpose of evaluating the possibility of using concentrate feed «URGA» and «Bazell-M 1» when feed- ing dairy cows and their effect on their milk production, composition and properties of milk. Found that cows, which received feed concentrate «URGA», significantly surpassed the control group cows according to yield of milk per lactation on 1237.5 kg or 14.0 %, while average daily milk yield of 29.88 ± 0.34 kg. At the same time animals of group 3 also significantly exceeded cows 1 group at P ≤ 0.05. Calculations of the biological efficiency of cows showed the superiority of that of cows experimental groups 2 and 3. From them was received more dry matter per 100 kg live weight at 32.22 and of 19.67 kg or 18.0 and 11.0 %, than from the animals of the 1st group. The same data were obtained when calculating the coefficient of biological value. The physical and chemical indicators of milk cows it was found that the best food value of milk from cows of the experimental groups.
Keywords: milk productivity, cows, food additives, physical and chemical indicators of milk.
