The objectives of Exp. 1 were to determine and to compare the chemical composition of canola meal from crushing plants in North America with 00-rapeseed meal from crushing plants in Europe, and to compare 00-rapeseed meal from solvent extraction procedure with 00-rapeseed expellers from expeller extraction procedure. Results indicated that concentrations of sucrose, P, K, Zn, and glucosinolates are greater (P < 0.05) in 00-rapeseed meal than in canola meal. Concentrations of GE and acid hydrolyzed ether extract (AEE) are greater (P < 0.05) in 00-rapeseed expellers than in 00-rapeseed meal, but concentrations of CP, Thr, ash, sucrose, crude fiber, NDF, ADL, hemicellulose, Ca, K, Mg, Mn, P, and S were greater (P < 0.05) in 00-rapeseed meal than in 00-rapeseed expellers. In Exp.2, the objective was to determine and to compare the apparent ileal digestibility (AID) and standardized ileal digestibility (SID) of CP and AA in canola meal, 00-rapeseed meal, and 00-rapeseed expellers when used in growing pig diets. Results indicated that the SID of Lys, Met, Thr, and Trp in canola meal were 70.6, 84.5, 73.0, and 82.6%. Values for 00-rapeseed meal were 71.9, 84.6, 72.6 and 82.6%, and in 00-rapeseed expellers, values were 74.7, 87.1, 74.0, and 83.4%, respectively. The SID of CP and all AA except Thr, Trp, and Gly in 00-rapeseed expellers were greater (P < 0.01) than in 00-rapeseed meal. In Exp. 3, DE and ME in canola meal, 00-rapeseed meal, and 00-rapeseed expellers were determined. Average DE and ME values in canola meal were 3,378 and 3,127 kcal/kg DM, whereas DE and ME in 00-rapeseed meal were 3,461 and 3,168 kcal/kg DM, and in 00-rapeseed expellers, values were 4,005 and 3,691 kcal/kg DM, respectively. Results indicated that 00-rapeseed expellers have greater (P < 0.01) DE and ME than 00-rapeseed meal. In Exp. 4, the objectives were to determine apparent total tract digestibility (ATTD) and standardized total tract digestibility (STTD) of P in canola meal, 00-rapeseed meal, and 00-rapeseed expellers, and to determine the effect of using microbial phytase in diets containing canola meal, 00-rapeseed meal, and 00-rapeseed expellers. The ATTD and STTD of P were 44.99 and 48.82% in canola meal, 45.77 and 50.36% in 00-rapeseed meal, and 44.83 and 48.60% in 00-rapeseed expellers. The ATTD and STTD of P increased (P < 0.001) by 19.09 and 19.15 percentage units for canola meal, 16.76 and 16.90 percentage units for 00-rapeseed meal, and 24.45 and 24.39 percentage units for 00-rapeseed expellers if microbial phytase was used in the diets. In conclusion, with a few exceptions, the concentration of energy and nutrients in canola meal and 00-rapeseed meal is not different. However, the concentration of glucosinolates in canola meal is less than in 00-rapeseed meal. The concentrations of AEE and GE in 00-rapeseed expellers are greater than in 00-rapeseed meal, but the concentrations of most other nutrients in 00-rapeseed meal are greater than in 00-rapeseed expellers. The digestibility of energy, CP, and most AA is not different between canola meal and 00-rapeseed meal, but the values in 00-rapeseed expellers are greater than in 00-rapeseed meal. Phosphorus digestibility is not different between canola meal and 00-rapeseed products, but the ATTD and STTD of P will be improved if microbial phytase is used in the diets.
