  1. aPigs were fed a high-fat high-fiber diet (HF) or a low-fat high-starch diet (LF). Duration of the feeding trial was 58.5 ± 0.5 days for all pigs. Two divergent pig lines that have been selected over eight generations for residual feed intake (RFI), a measure of feed efficiency, were used. Pigs selected for low RFI were the most efficient in the conversion of food to weight gain. There was no significant interaction (p > 0.10) between diet and line on performance and adiposity traits. At the end of the trial, weights of perirenal and dorsal subcutaneous adipose tissues (AT) were used as surrogates of body adiposity
