Three growing and three finishing [Duroc x (Yorkshire x Landrace)] barrows (body weight = 22.68 +/- 0.18 kg and 49.43 +/- 0.78 kg) were used in this 3 x 3 Latin square experimental design to evaluate the comparative effects of soybean meal (SBM), rapeseed meal (RSM), and canola meal (CM) on apparent total tract digestibility (ATTD) and apparent ileal digestibility (AID) in growing and finishing pigs. Growing pigs provided with the SBM and CM diets had higher (P < .05) ATTD of N than those pigs fed the RSM diet, and the AID of N of pigs fed the CM diet was higher (P < .05) than those fed the RSM diet. Moreover, the AID of lysine, threonine, and valine in the SBM and CM treatments was higher (P < .05) than that in the RSM treatment. In finishing pigs, the ATTD and AID of dry matter were increased (P < .05) in SBM compared with RSM, and pigs fed the SBM and CM diets had higher (P < .05) AID of N than pigs fed the RSM diet. In addition, pigs fed the SBM and CM diets had higher (P < .05) AID of histidine, methionine, and glutamic acid than those fed the RSM diet.
