59 Swedish Landrace pigs (20 boars, 20 gilts and 19 barrows) were fattened on a commercial farm for 200 days to test the influence of sex on carcass traits and muscle fibres and fat cells diameter. After slaughter backfat thickness on different anatomical locations, muscle and fat area on carcass cross-section behind last rib and meat quality traits were evaluated. Carcass weight and net daily gain did not differ among sex (p0.05). Boars had thinner backfat and smaller fat area on carcass cross-section behind last rib than gilts and barrows (p0.05). Differences between gilts and barrows in fat thickness and area of longissimus dorsi were not significant (p0.05). Barrows had greater area of longissimus dorsi than boars (p.05). Sex did not influence muscle fibres and fat cells number per mm2 and diameter neither meat quality traits, like colour, exudity and texture (p0.05).
