COMPOUND FEED FOR YOUNG PIGS, BALANCED IN TERMS OF DIGESTIBLE ESSENTIAL AMINO ACIDS
Abstract
Energy is necessary for all biological processes occurring in a living organism. It is produced as a result of the oxidation of organic compounds contained in feed ingredients. In this regard, the evaluation of feed and rationing of digestible (assimilable) amino acids are of great importance. Therefore, the purpose of this work was to establish the optimal ratio of digestible lysine and metabolizable energy in compound feed for growing fattening young pigs. In the course of the research, two scientific and economic experiments on young pigs were carried out at the school-farm of the State Enterprise “ZhodinoAgroPlemElita”: the first one – on piglets of 2-4 months of age, the second one – on fattening piglets. The research revealed the optimal ratio of digestible lysine and metabolizable energy in the diets of pigs, contributing to the ultimate manifestation of their production traits. Diets for growing-finishing piglets, containing 13.5 MJ of metabolizable energy and 10.5 g of digestible lysine, and diets for pigs of I and II fattening periods, containing 13.0 MJ of metabolizable energy and 8.3 and 8.0 g of digestible lysine, contribute to the full realization of their genetic potential. Thus, the experimental animals were characterized by the highest average daily gain in live weight, the minimum consumption of compound feed, metabolizable energy, the smallest fat thickness and the largest loin eye area.
