Abstract. Fully balanced feeding of animals is the basis for realizing the potential of animal productivity. The use of targeted high-protein feed supplements in feeding diets for highly productive cows is a definite part of this. The article presents the results of studies on feeding increased levels of feeding to cultured cows during the second lactation and their impact on milk productivity and body mass gains. The research was conducted in one of the tribal farms of the Moscow region. Highly productive animals according to the principle of pairs of analogues were divided into 3 groups - control and two experimental. The feeding of experimental animals was carried out according to the basic diet adopted in the farm. Improvement of the feeding level in the experimental groups was achieved through individual feeding of targeted protein-vitamin-mineral concentrate (PVMC). The results of the studies showed that increasing the feeding rate of highly productive cows of second lactation by 4-5% and 8-9% had a positive effect on the gross milk production. Animals – 1 nd experimental group produced 307.52 kg more milk; 2rd experimental group produced 494.52 kg or 3.58% and 6.19%, respectively, than from the control cow. The dynamics of change in the increase of the live mass of cows 2-by the experimental group showed that with the increase of daily yield, less nutrients of the own body are spent on milk production. The average daily increase in living mass in cows of the 2rd experimental group, when the energy balance was positive, was 187.6 g in the control variants, and 312.3 g in cows of the 3rd experimental group (with p=0.01).
