The aim of this study was to determine the amino acid composition and its comparison in different muscles musculus longissimus lumborum (MLL) and musculus semimembranosus (MS) in wild boars with a comparable body weight and representing the same age class. The research involved 10 wild boars. Samples for testing were taken from the central part of the following muscles: MLL, MS. The content of amino acids in the samples was determined with the automatic amino acid analyzer AAA-400 (INGO's). The levels of respective amino acids in muscle MLL were within the range from 5.33 (Tyr) to 22.67 (Glu) g • kg-1, and in muscle MS – from 6.24 (Tyr) to 24.77 (Glu) g • kg-1. It was found that the total content of essential amino acids was higher in muscle MS as compared with muscle MLL. The significant differences (at p ≤ 0.05) were found for Ser, Gly, Ala, Asp, and Glu. Analyzing the differences in the amino acid composition between muscles MLL and MS, it was found that the average level of all the amino acids in MS was higher.
