¹Diets contained 50% 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.

²Least squares means based on eight observations per diet.

³Contrast CM vs. extruded CM.

⁴Analyzed using contrast for the three extruded CM diets.

⁵AHF = ATTD – AID.
