It is determined that feeding heifers with biological vitamin and mineral supplement (BVMS), containing rape, lupine and mineral and vitamin supplement based on halite, phosphor-gypsum, phosphate, sapropel and premix in the amount of 20-25 % on mass of mixed feed instead of sunflower cake, within the diet with green mass made of cereal-legumes mixture of 56-57 %, mixed feed - 36-37 %, treacle - 6-7 % is of a positive effect on nutritional value and feeds intake, rumen digestibility indices, morphological and bio-chemical blood content? And allows to obtain the average daily weight gain of 827-812 g with forage spends per 1 c of weigh gain of 7,0-7,2 c forage units. Implementation of feed supplement in diets for animals allows to decrease prime cost of mixed feeds at 12-15 %, and prime cost of 1 c of weigh gain - at 11-13 %. The profit of prime cost decrease of 1 c of weight gain is increased at 7-10 %.
