Efficiency of diets with increased metabolizable energy in the feeding of young cattle

To fully unleash the genetic potential of meat productivity of cattle, a detailed study of all major factors affecting the production abilities of animals is required, one of which is energy consumption. Energy rationing is the most important condition of nutrition, which determines the level of animal productivity. The paper contains the materials of research aimed at determining the productivity of young cattle of 13-18 months of age raised for meat at different levels of energy nutrition. It was found that feeding diets with high level of metabolizable energy and optimum rate of protein breakdown to young bulls made it possible to obtain 1103-1100 g of body weight gain. Raising young bulls on the studied diets had a positive effect on slaughter traits and made it possible to obtain a slaughter yield of 53.6-54.6 %.
