OF THE LONGEST BACK MUSCLE OF KEMEROVO PIGS AND THEIR CROSSBREEDS WITH COMMERCIAL BREEDS

Abstract

The results of the assessment of the amino acid profile of the longest muscle of the back of the Kemerovo breed of pigs and its two-breed and three-breed crosses with commercial breeds are presented. The largest amount of amino acids is found in the meat of purebred animals in comparison with two- and threebreed animals. In terms of the content of such amino acids as phenylalanine, aspartic acid, serine, glutamic acid, purebred animals significantly exceeded hybrids. It was shown that the studied groups of animals for all amino acids exceeded the FAO reference values, with the exception of lysine. The influence of gender on the amino acid composition of meat in purebred animals was revealed, since boars significantly exceeded pigs in 8 amino acids out of 17 studied. Reliable correlation coefficients were established between the content of a number of amino acids in meat samples, which coincide in all groups of pigs.
