Values are expressed as means and SEM.

^a-cMeans in a same row with different superscript letter differ significantly at ^*p < 0.05, ^**p < 0.01, ^***p < 0.001.

D, Duroc (n=79); P, Pietrain (n=42); DP, crossbred Duroc × Pietrain (n=45); C, castrate; G, gilt; SEM, standard error of means; ns, not significant; SFA, saturated fatty acid; USFA, unsaturated fatty acid; MUFA, monounsaturated fatty acid; PUFA, polyunsaturated fatty acid; UFA, unsaturated fatty acid.
