CECHOVA, M., Z. HADAS, J. NOWACHOWICZ and P. D. WASILEWSKI, 2012. The effect of feed with the addition of conjugated linoleic acid or sunflower oil on fatty acid profile of crossbred pig’s meat. Bulg. J. Agric. Sci.,18: 827-833
The aim of the paper was to investigate the impact of feeding pigs with 2 % addition of sunflower oil (SFO) or conjugated linoleic acid (CLA) on fatty acid profile of Longissimus dorsi muscle. The subjects of research were 116 crossbred gilts divided into 3 groups (SFO, CLA and control). The addition of sunflower oil or conjugated linoleic acid started at the time when the weight of the pigs ranged 82 kg, averagely. Conditions for the maintenance, care and nutrition of all experimental fatteners were standardized. Diet was available semi ad libitum. Animals were slaughtered at c.a. 120 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 pigs from experimental groups getting the addition of sunflower oil or conjugated linoleic acid had higher amount of polyunsaturated fatty acids (PUFA) and essential fatty acids (EFA) as compared to the animals from the control group what was proved by statistical differences.
