Three metabolism trials were conducted to determine the effect of grain source and dietary level of oat hulls on dry matter digestibility, P and Ca retention and intestinal phytase activity of growing pigs. Twenty-four crossbred pigs (39 kg)were used. Dry matter digestibilities of corn-based diets were greater (P<.01) than grain sorghum-based diets (74.7 vs 63.5%). Diets containing 10% oat hulls had lower (P<.01) dry matter digestibilities than diets containing no oat hulls (64.0 vs 74.2%).
