1Diets contained 20% canola meal; CM, canola meal, ground but not extruded; CM-250, CM extruded at 250 rpm screw speed; CM-350, CM extruded at 350 rpm screw speed; CM-450, CM extruded at 450 rpm screw speed; SBM, soybean meal.

2Least squares means based on 10 pen observations of 4 pigs per diet.

3For ADFI, ADG, and feed efficiency, a week effect was observed (P < 0.001), but an interaction between diet and week was not observed (P > 0.05).

4Contrast SBM diet vs. three extruded CM diets.

5Contrast CM diet vs. three extruded CM diets.

6Analyzed using contrast for the three extruded CM diets.
