Biological value of the meat protein of Edilbaev lambs when enriching diets with es-sential microelements

Abstract

The article presents the results of studying the quality and usefulness of the protein in meat products obtained from lambs of the Edilbaev breed. The experiment involved one control and three experimental groups of animals, the diet of which was enriched with essential microelements in the form of feed additives "Yoddar-Zn" and "DAFS-25". The results of the research showed that in the rams of the experimental group, which were fed in combination with the main diet supplements Ioddar-Zn and DAFS-25, the maximum amino acid score and protein-quality index were noted, which indicates a high biological value of meat. According to the coefficients of utility and comparable redundancy, it is assumed that in the meat of rams from the control group, amino acids are better balanced and can be more rationally used by the human body. Among the experimental groups of young sheep, the meat of the experimental group, where two feed additives were used at once, had the best rationality.
