Lipid composition of the muscle Semimembranosus was analyzed in the offspring of five different sire genetic types: Danish Duroc (DU), Dutch Large White (LW D ), English Large White (LW E ), Belgian Landrace × Landrace (EL × LR) and Belgian Landrace (BL), all of them mated to Landrace × Large White sows. The animals sired by DU boars showed the highest intramuscular fat, nonpolar lipid and free fatty acid contents. Fatty acid composition of triglycerides was little affected by genetic type. However, the fatty acid composition of phospholipids was strongly affected, the highest monounsaturated fatty acid (MUFA) and the lowest polyunsaturated fatty acid (PUFA) percentages being found in the animals sired by BL × LR boars. On the other hand, the animals sired by BL boars, which showed the highest phospholipid content, showed the highest PUFA percentage.
