This article presents data on the use of a new protein feed additive based on colostrum oil, protein hydrolysate and vitamin C, developed at the Department of Feeding, Animal Hygiene, Technology of Production and Processing of Agricultural Products of the South Ural State Agrarian University. The presented materials indicate that bulls showed high average daily gains in all age periods. The bulls had fairly high growth energy, which was due to their genetic characteristics. At the same time, good results were obtained when raising and fattening animals that received, in addition to the main diet, a feed additive based on colostrum oil in the amount of 100 g per head per day. The results of the control slaughter show that the best slaughter qualities were characterized by the bulls of the experimental group, which received a feed additive in addition to the diet (in terms of carcass yield, fat yield, slaughter yield).
