Abstract
Diets based on sorghum and casein were given to pigs. Sorghum was dry rolled (C) or ground in a hammer mill through 6.4 mm (M) or 3.2 mm (F) screens, producing particles with a modulus of fineness of 3.57, 2.85 or 2.36, respectively. Each successive reduction in particle size improved (P<0.05) the apparent ileal digestibility of DM, starch, gross energy and N. Digestibilities of these components were highest (P<0.05) for the F diet but they did not differ between diets M and C because of increased disappearance in the large intestine of DM, starch and gross energy from the C diet. N loss in the large intestine was also greater for pigs given diet C than for those given diet M, but the difference was not significant. The digestibilities of most amino acids at the terminal ileum were improved (P<0.05) as particle size decreased. Lysine digestibilities were not affected. Amino acid digestibilities were consistently higher (P<0.05) for diet F than diets M and C, which did not differ from one another. A comparison of ileal and total tract digestibilities indicated a net disappearance of all amino acids except lysine during large intestine transit
