Carbohydrases in 25% canola-meal diet consumed freely by weaned pigs: increased daily gain (up to 13%), increased feed intake (up to 16%), did not affect feed efficiency, reduced viscosity of digesta in ileum, and did not affect nutrient digestibility. Beneficial effects of enzyme supplementation to a wheat-canola meal diet fed to weaned pigs were not related to improved nutrient digestibility, but rather to increased feed intake. The increase in feed intake is hard to explain directly. However, reduced viscosity of digesta in the distal small intestine suggests that increased feed intake is related to an increased passage rate.
