Abstract: Amino acids (AA) are the important markers of the state of protein metabolism, and therefore the study of the amino acid composition of animal tissues is an urgent task. This article presents the results of amino acid analysis of the blood serum of fattening pigs of the Landrace breed and twobreed hybrids (Landrace·Large White) depending on the duration of fattening. Fattening pigs (n=40) were divided into 6 groups depending on the breed and duration of fattening: A-2 – 60 days of fattening Landrace pigs, B-2 – 60 days of fattening F1 Landrace Large White, C-2 – 70- 80 days of fattening a Landrace pig, D-2 – 70-80 days of fattening F1 Landrace Large White, F-2 – 100 days of fattening a Landrace pig, S-2 – 100 days fattening F1 Landrace Large White. The most stable amino acids in blood levels are tyrosine, histidine, threonine, phenylalanine, glycine and proline in all studied groups of animals. According to the results obtained, changes in the AA composition of blood serum are largely due to the duration of fattening (as a one of the key feed factors) and the genotypes of animals.
