<abstract xmlns="http://www.w3.org/1999/xhtml"><p> This study evaluated the effect of intramuscular fat (IMF) content on the quality of pig carcass and meat. One hundred and twenty right half-carcasses of crossbred pigs (Pietrain × Duroc boars and Polish Large White × Polish Landrace sows) from a commercial farm were divided into two groups depending on the content of IMF in the longissimus muscle (LM): LIMF - lower content (mean 2.05% IMF; 28 gilts and 30 barrows) and HIMF - higher content (mean 3.08% IMF; 32 gilts and 30 barrows) were used. Pigs with a higher IMF content in LM (HIMF group) had a significantly lower (P≤0.01) percentage of lean meat in carcass, loin muscle area, level of polyunsaturated fatty acids (PUFAs) and PUFAs/SFAs ratio, whereas backfat thickness, content of cholesterol in LM, levels of saturated fatty acids (SFAs) and monounsaturated fatty acids (MUFAs) were significantly greater (P≤0.01) than those in pigs with lower IMF content (LIMF group).</p></abstract>
