Fatty acid profile of <i>Longissimus dorsi</i> muscle of crossbred pigs fed with addition of conjugated linoleic acid or sunflower oil

Abstract

Abstract. The aim of the paper was to investigate the impact of feeding pigs with different levels of conjugated linoleic acid or sunflower oil on fatty acid profile of Longissimus dorsi muscle. The subjects of research were 60 crossbred gilts divided into 6 groups, fed with different levels of conjugated linoleic acid (CLA) or sunflower oil (SFO) (0.5; 1.0 and 2.0 %, respectively). All fatteners were kept and fed under standardized conditions. Animals were slaughtered at 95 kg of body weight. Fatty acid profile was determined in samples of Longissimus dorsi muscle from each animal. Gas chromatography was used (in the research). The significance of differences between groups was verified by Duncan’s test. In the present study the addition of conjugated linoleic acid or sunflower oil did not impact the composition and amounts of saturated or unsaturated fatty acids in Longissimus dorsi muscle.
