Abstract
The aim of this study was to evaluate the effect of including different percentages of Duroc (D) breed in maternal line [Landrace (LR)×Large White (LW); LR×(LW×D); LR×D] and gender on meat quality and intramuscular (IMF) and subcutaneous (SCF) fatty acid composition. No significant differences were found among dam lines in ultimate pH, L* values and drip and cooking losses. There were higher percentages of saturated fatty acids in LR×D and LR×(LW×D) lines and higher percentages of polyunsaturated fatty acids in LR×LW line in IMF and SCF. Also, LR×D line produced pork with a lower Warner–Bratzler shear force values and higher IMF content and potential of lipid oxidation. Furthermore, the L*, a* and b* values and drip loss were greater in pork from entire males than females. The IMF and SCF of females were more monounsaturated and less polyunsaturated than those from entire males.
