| The nutritional value of biodiesel co-products were studied for swine. In Exp. 1, expeller-pressed canola meal was nutritionally characterized and validated for grower-finisher pigs. Expeller-pressed canola meal provided adequate energy and AA; ADG was reduced 3 g/d per 1% expeller-pressed canola meal inclusion in diets formulated to equal NE and SID AA, due to 5 mumol/g dietary glucosinolates. In Exp. 2, cold-pressed canola cake samples from 4 different processing conditions were tested against expeller-pressed canola meal and seed in a digestibility study. Higher residual oil in the cake increased the DE and NE content. In Exp. 3, 15% of either solvent-extracted or expeller-pressed canola meal with or without 5% glycerol was tested against a soybean meal diet for weanlings. Solvent-extracted or expeller-pressed canola meal, or in combination with 5% glycerol can partially replace soybean meal in weaner diets formulated to equal NE and SID AA content without affecting growth performance. |
