Abstract

Adequate nutrition of ruminants and physiologically correct assessment of the nutritional value of feed rations
need additional knowledge about the quantitative transformation of the main components of any particular feed
in diff erent parts of the digestive tract. The study of the principles of substrate energy use is necessary in each
particular case to defi ne the actual need in substrates, which determines the effi ciency of their use for implementing
biosynthesis and physiological functions. The determination of the infl uence of the energy supply of the diet
of young cattle aged 7-12 months on the effi ciency of energy use in the organism. Effi ciency of the use of metabolizable
energy of diets for calves with the increased level of energy nutritional value by 5.0% (MEC is equal to
9.6 MJ/kg) promoted the increase of energy deposition and weight gain synthesis by 10.04%, weight gain energy
by 19.50%, the effi ciency of the use of metabolizable energy for weight gain by 3.81%.
