METHOD FOR RAISING PRODUCTIVITY OF BULL-CALVES OF MEAT BREEDS IN CONDITIONS OF DEFICIT OF MICRONUTRIENTS

摘要

A method for raising the productivity of feeder bull-calves of meat breeds in conditions of deficit of micronutrients includes activating protein biosynthesis in animal organism by supplementing feed rations with a mixture of salts of deficit micronutrients (Cu, Co, Zn, Mn, Fe) of an organic acid while mixing thereof with a mixed feed or concentrated feeds. A mixture of salts of deficit micronutrients of lactic acid is used. It is additionally enriched with selenium on versene, starch iodine and vitamins A, D, E, antioxidant Thermox TM BSP and protected vegetable oil.
