Analysis of influence of gene polymorphism CAPN1 on the amino acid composition of the flesh of bulls Kalmyk breed. The study was conducted using modern equipment by capillary electrophoresis, using the system of «Drops». Analysis of the obtained data allowed to reveal certain changes in the content of amino acids in muscle tissue of animals in connection with presence of a mutant allele of a gene CAPN1 different groups studied. According to the results of the study revealed substantial differences in the content of valine, phenylalanine, in muscle tissue. In samples from individuals of the 2nd group, the content of these amino acids were higher than a similar level in the I and III groups of 11.7 %, 12.8 % and 1.7 % and 18.8 %. Maximum dynamics observed in the number of phenylalanine in comparison with I and III group, in percentage terms, the difference grew by 12.8 % and 18.8 %, respectively. In respect of methionine and threonine the difference between the groups did not exceed 3–5 % in favor II. In experimental studies have been identified differences that investigated meat that contains a reduced level of valine, methionine and phenylalanine. Despite the low content concerning the standard (30.6% below norm) differences within groups. So, the content of valine prevails in the II and III groups in comparison with I 3,6 %.
