In process of animal husbandry intensification much attention should be given to maintenance of the high-grade balanced feed of animals. Forage supplement Profat (Protected Fat) is a protected fat in dry-sand mould with 84% of fat content. Application of 0,5-0,8 kg of dry fat supplement in cows diets per 1 head a day (4,7-10,0% in mixed forage content) promotes the increasing of prime cost of milk yield with basic fatness at 1,8-2,8% within fatness growth at 0,1-0,24% without protein content decrease. During the analysis of morphological and biochemical blood structure there was not established any considerable inter-group distinctions. At the same time, it is necessary to notice, that in blood of animals of two experimental groups there was stated a little bit higher protein content. However, in proportion to application of experimental fat additive up to 0,8 kg per head a day the protein content decreased. The increased number of erythrocytes and hemoglobin content in blood of animal of trial groups proved the strengthening of metabolic processes. In blood of trial groups it was noted high quantity of vitamin A and phosphorus as well as lower amount of calcium
