The objectives of this study were a) to compare the apparent total tract digestibility (TD) between non-cannulated (intact) and cannulated (steered ileo-cecal valve technique, SICV) pigs fed diets differing in energy density (Exp. 1) and b) to compare the direct vs marker (Cr2O3) methods for estimation of the TD and apparent ileal digestibility (ID) in SICV-cannulated pigs (Exp. 2). In Exp. 1, 24 intact and 18 SICV-cannulated castrates of approxi- mately 40 kg initial BW were randomly assigned to six treatments in a 2 × 3 × 2 factorial arrangement (two pig types, three carbohydrate sources, and two fat levels). In Exp. 2, the same SICV-cannulated pigs from Exp. 1 were given those treatments in a 2 × 3 × 2 factorial arrangement (two methods of digestibility estimation, three carbohydrate sources, and two fat levels). In both experiments either cornstarch, soy- bean hulls, or pure cellulose, without or with fat, were
