Abstract
The effects of feeding various fat sources on contents of trans fatty acids (TFA) and n−3 polyunsaturated fatty acids (n−3 PUFA) and on cholesterol incorporation in muscle and adipose pork tissue were studied. Thirty castrated pigs, divided into three experimental groups receiving the same basal diet with a different 4% supplement of fathydrogenated oil (H), linseed oil (L), and pomace oil (O)were slaughtered at 95 ± 2.16 kg. No differences were observed in production performance and in carcass and meat characteristics. The pattern of dietary fatty acids was reflected in muscle and adipose tissues. In backfat, animals fed H had the highest TFA contents. Animals fed O had the highest MUFA contents. Animals fed L had the highest levels of n−3, greater contents of C20:5n−3 (eicosapentaenoic acid) and C22:5n−3, and lower levels of arachidonic acid (C20:4n−6). Dietary treatment did not affect cholesterol concentration. Keywords: Trans fatty acid; cis MUFA; n−3 PUFA; pig carcass
