<jats:p>&lt;p&gt;&lt;strong&gt;Abstract.&lt;/strong&gt; This study investigated the effects of breed on the fatty acid compositions of the &lt;i&gt;Longissimus thoracis et lumborum&lt;/i&gt; (LTL) of gilts and barrows. Although only one muscle was analyzed, the results gave a good indication of the effect that breed and sex may have on the fatty acid compositions of the meat. Breed exhibited a significant effect on the fatty acid composition of pigs, whereas the effects of sex were found to be minor. Higher contents of intramuscular fat (IMF), C16 : 1, C18 : 1 and monounsaturated fatty acids (MUFAs); darker color of meat; and lower cholesterol content, drip loss, C18 : 0, C18 : 2, polyunsaturated fatty acids (PUFAs), n-6 and n-6 : n-3 ratios were found in the LTL muscle of Pulawska pigs compared with Polish Landrace pigs. Meat of Pulawska pigs is especially suitable for the production of good-quality, cured and smoked loin for longer storage. Fat content was higher in barrows than in gilts, and as a consequence the IMF from barrows had higher saturated fatty acid proportions and hypercholesterolemic acids (OFAs) as well as lower C18 : 1 than that from gilts.&lt;/p&gt;
