Sažetak
The aim of this research was to assess supplementation of pig diet with rapeseed oil that is rich in LNA (C18:3), n-3) in order to examine the possibility to increase the content of PUFA n-3 in meat. Carcass traits and physical-chemical traits were also determined, as these are the factors that affect the nutritive value of meat. Sixty pigs (LWxGL) were divided into three groups, and fed from 30 up to 100 kg of live weight. They were fed ad libitum with control diets (1st group) and experimental diets (2nd and 3rd group). Control diets contained maize, extruded soybean, fish flour, salt, limestone, phosphonal, synthetic lysine and premix and were balanced at 14.08 MJ.kg-1 ME and 155.9 g of crude protein. Instead of mixtures with maize and extruded soybean, the 2nd and 3rd experimental group were fed mixtures containing 3% and 6% of rapeseed oil, respectively, and had 14.68 MJ.kg-1 ME and 153.0 g of crude protein, and 14.72 MJ.kg-1 ME and 150.0 of g crude protein, respectively. Supplementation of rapeseed oil in pigs’ diets had statistically significant effect (P<0.05) on the increase of muscular tissue in shoulders and on the lowering of fatty tissue in back part. Muscular tissue of all pig groups was of good quality (pH45, pH24, W.H.C.). In comparison to the control, statistically significantly more (P<0.05) LNA and  PUFA n-3, and more favorable VLCE were determined in MLD samples of pigs fed with rapeseed oil supplemented in the amount of 3% and 6%.
