Meat productivity of red steppe bulls (Kuban type) under different conditions of keeping
The aim of the study was to study the influence of various technological methods of rearing young animals on their growth, development and meat productivity. Considered are such technological methods as keeping young animals on the walking and feeding grounds in the summer, their daily exercise in winter, and intramuscular administration of a concentrate of vitamins A and D. bull 48 kg. The study continued until the youngsters reached 16 months of age. The results of the study indicate the positive effect of walking bulls and intramuscular injections of vitamins A and D on the consumption of bulky forages, digestibility and nutrient utilization of the diets. It has been proven that with the walking content, intramuscular administration of vitamins A and D to bulls contributed to an increase in their slaughter weight at the age of 14 months by 8.3 % and at the age of 16 months - by 10.1 %. The study of the chemical composition of meat showed that, in general, for the groups with age, there was an increase in the fat content in the meat of gobies, while the amount of water decreased, the level of protein increased slightly, i.e. beef obtained by slaughtering bulls at the age of 16 months most fully met the requirements for meat of adult animals.
