PRODUCTIVITY OF YOUNG CATTLE WITH DIFFERENT LEVELS OF ENERGY NUTRITION

Abstract

Arrangement of balanced feeding, satisfying the need of animals in basic nutrients and biologically active substances, contributes to the fullest manifestation of their genetic potential of productivity and obtaining high-quality products. A special place in animal feeding is given to providing energy, as it is necessary to ensure physiological functions of the organism and for the synthesis of products. The paper presents the results of research aimed at determining the productivity of young cattle raised for meat production with different levels of energy nutrition. Studies showed that the use of diets with different energy content and a ratio of degradable to non-degradable protein of 65:35% in the feeding of experimental animals made it possible to obtain 10491051 g of gain per day, while reducing feed costs per 1 kg of gain over a raising period of 6-12 months by 3.6-5%.
