The aim of this study was to examine variability in chemical and cholesterol content, fatty acid composition in musculus longissimus lumborum et thoracis (MLLT) and pH in MLLT and musculus semimembranosus (MS) of various genotypes of pigs. Out of 30 male castrated animals used in the trial, 20 were Mangalitsa pigs (Swallow Belly - SBM and White - WM) while 10 were of the Swedish Landrace breed - SL (the most frequent meat/fattening breed in Serbia). The initial (pH45) and final (pH24) values of MLLT and MS clearly differed depending on the genotype of pigs, WM and SBM. The total fat content was higher in WM and SBM pigs, compared to SL pigs (P < 0.001 and P < 0.01, respectively). The SL pigs had a higher percentage of water in MLLT, than SBM and WM (P < 0.001). In our research, WM pigs had lower protein content in MLLT compared to SL pigs (P < 0.01). The representative of pig meat breeds, SL had significantly less cholesterol in MLLT compared to SBM and WM pigs (- 14.83% and -15.44%, P < 0.001). However, differences in the content of saturated and unsaturated fatty acids were more expressed and distinct. A higher percentage of saturated fatty acids (SFA) and polyunsaturated fatty acids (PUFA) were established in MLTT originating from SL pigs compared to both Mangalitsa strains (P < 0.001). The total monounsaturated fatty acids (MUFA) and unsaturated fatty acids (USFA) content was higher in SBM and WM than in SL pigs (P < 0.001).
