CHANGE OF THE BACKFAT FATTY ACID PROFILE OF CROSSBRED PIGS FED WITH THE FODDER WITH ADDITION OF SUNFLOWER OIL AND CONJUGATED LINOLEIC ACID

摘要

The aim of the research was to compare the backfat fatty acid profile of pigs fed with sunflower oil (SFO) and conjugated li-noleic acid (CLA) and animals not receiving SFO or CLA addition (control group). The experiment covered 116 crossbred pigs, divided into three groups: two experimental (n = 40) and control (n = 36). In the experimental groups animals were fed the fodder with addition of 2 % sunflower oil (SFO) or conjugated linoleic acid (CLA). The fatteners were kept and fed in uniformed conditions. The animals were slaughtered at 120 kg of body weight. The fatty acid profile was determined on backfat samples from each animal using gas chromatography. The pigs from experimental groups had higher content of saturated fatty acids (SFA) and hypercholesterolemic acids (OFA) and also lower content of unsaturated fatty acids (UFA, MUFA) and hypocholes-terolemic acid (DFA) as compared to the animals from the control group, which was confirmed by statistical differences.
