Four Corriedale wethers averaging 45 kg of body weight were randomly assigned to a 4 x 4 Latin square to evaluate the effects of two carbohydrate sources (soybean hulls and corn grain) and two dietary forage levels (40 and 70%) on nutrient digestibility, N balance, and portal nutrient flux. Animals were fitted with catheters in the mesenteric and portal veins and in the mesenteric artery. Digestibility of nutrients and N balance were determined by total collection of feces and urine.
