| Summary: | The effect of a vitamin and vitamin – mineral supplement on the chemical composition and quality of meat was studied on 9 rams of the Borzakh breed that have rumen cannulas. It was found that the addition of vitamin and vitamin – mineral supplements to the diet of sheep meat improves the chemical composition and nutritional value of meat. Under the influence of these feed additives such indicators as protein, fat and ash in the composition of meat increased. Also, it was found that in meat in animals fed in the composition of the diet vitamin and vitamin – mineral premixes increases the calorie content of the meat. It was also noted that in meat in animals fed in the composition of the diet vitamin and vitamin – mineral premixes increases the protein – quality index (tryptophan: hydroxyproline). Thus, the addition of vitamin and vitamin – mineral premixes to the diet of fattening rams stimulates the chemical composition and nutritional value of meat.
