Pigs were fed for 4 week pelleted diets containing 150 g/kg of solvent-extracted or expeller-pressed canola meal either with 0 or 50 g/kg crude glycerol or a soybean meal control diet to measure performance and diet nutrient digestibility. The wheat-based diets were formulated to contain 9.45 MJ/kg net energy (NE) and 1.13 g standardised ileal digestible (SID) lysine (Lys)/MJ NE. Glycerol increased (P<0.05) diet digestible energy content by 0.6 and 0.2 MJ/kg of dry matter for solvent-extracted and expeller-pressed canola meal diets, respectively. Canola co-product diets had a lower (P<0.05) nutrient digestibility than the control diet, while DE content did not differ. For days 0-28, BW gain and feed efficiency did not differ between the types of canola meal, the two levels of glycerol, and the canola co-product diets and control diet, although feed intake was 6% higher (P<0.05) for the control than canola co-product diets. In conclusion, 150 g/kg of solvent-extracted or expeller-pressed canola meal or with 50 g/kg glycerol can partially replace soybean meal and wheat in diets formulated to equal NE and SID amino acid content fed to weaned pigs without affecting growth performance. 收起
