Realization of veterinary and sanitary examination of meat and slaughter products of calves treated with hyperimmune serum against cattle colibacillosis was conducted in the conditions of the Republic of Belarus. There were formed two groups calves of 3-5 days old. Calves of the first group were treated with serum biological preparation of trial series produced at Vitebsk Biofabrika (Belarus). Calves of the second group were intact animals. Calves of each group were killed in 14 days after preparation application for realization of veterinary-sanitary examination. Slaughter meat was studied in accordance with the following indexes: pH; peroxidase activity; presence of products of primary protein breakdown; moisture content; relative biological value of meat; bacterial examination. The research results of organoleptic indicators showed that meat of both groups corresponded to the standards. Hyperimmune serum against colibacillosis of live-stock animals did not render negative influence on organoleptic, physical and chemical indexes of meat. Indexes of the relative biological value in meat of calves treated with the examined serum were higher than the similar indexes of intact animals. Meat of all examined animals did not have any germs of toxico-infections and toxicoses
