The objective of this study was to determine the effects of dietary supplementation with rapeseed and linseed oils on changes of the fatty acid profile in porcine meat. The research was conducted on 45 fattening pigs divided into three groups. Group 1 was given a diet with 2% of sunflower oil, group 2 was given a diet with 2% of rapeseed oil and group 3 was given a diet supplemented with 2% of linseed oil. The highest content of n-3 polyunsaturated fatty acids (PUFA) and the most favourable ratio of n-6/n-3 PUFA was determined in the meat of pigs that were fed diets with linseed oil (P less than 0.001), whereas the meat of pigs that were fed diets with sunflower oil had an unfavourable ratio of these acids. The results point out the necessity of finding out optimal portions of feeds rich in PUFA to improve the ratio of fatty acids in porcine muscle tissue.
