Biological and Methodological Aspects of the Distribution and Use of Energy in the Body of Animals

Abstract

The metabolism and use of energy in animals according to modern concepts was analyzed,since different schools have different interpretations and define different types of energy metabolism when studying metabolism in animals’ bodies. Results of research of the world's scientists on the feeding of farm animals and own 16-year study are substantiated, own system was proposed as a result. The advantage of the presented system consists in the fact that it avoids the use of not always valid objective ratios of digestibility of nutrients, but uses only one ratio of digestibility of energy defined on the basis of the actual chemical composition of forages. At the same time without complicated balance tests we can determine the digestibilityand metabolizable energy in feeds and diets.
