LEVEL OF METABOLIZABLE ENERGY IN COMPOUND FEED FOR YOUNG PIGS
Abstract
At the present stage of pig breeding, due to the widespread breeding of meat genotypes, progressive technological methods of feeding and housing of animals are introduced. The development of the industry poses new challenges in assessing and developing standards of animal needs for metabolizable energy, essential amino acids and other nutrients and biologically active substances. The aim of the work was to study the effect of the concentration of metabolizable energy in the diet on the indicators of growth, tissue gain and the rate of protein retention in pigs. It was found that rationing of compound feed for young pigs with a live weight of 20-40 kg in terms of metabolizable energy, digestible lysine and other essential amino acids, balanced in accordance with the concept of “ideal protein”, made it possible to satisfy their physiological needs for these nutrients. Feeding animals with compound feed containing 13.8 MJ of metabolizable energy and 10 g/kg of digestible lysine provided 621 g of daily live weight gain at minimum feed consumption (1.44 kg/day).
