The effect was studied of fattening lambs with a sunflower cake and linseeds, and a vitamin E added, on the fatty acid profile of fat from m. longissimus lumborum, liver, and heart. The rams in three groups were intensively fattened up to 32-37 kg with a mixture composed of cereal ingredients and rapeseed crush (K control group) or with a mixture of sunflower cake and linseeds (MSL; 23,5 and 5 percent respectively), as well as with a mixture containing the additive of vitamin E (MSL+E). The liver fat contained more SFA than the intramuscular and heart. The heart fat was characterized by the highest content of PUFA; 25,29 percent vs. 11,53 and 8,99 in the liver and intramuscular fat. The nutritional parameters of heart fat were most beneficial, and the liver and m. longissimus lumborum fat had the comparable nutritional values; PUFA: SFA was, respectively, 0,57 vs. 0,21 and 0,19. The feeding with oil components had no significant effect on the total SFA in the organs investigated. The investigated organs of MSL and MSL+L lambs had less CLA than the K control group
