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 fat - hydrogenated 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 arachidomc acid (C20:4n-6). Dietary treatment did not affect cholesterol concentration.
