1 Data are the least squares means of 6 observations for all diets. SEM, standard error of means; ADG, average daily gain; ADFI, average daily feed intake; ATTD, apparent total tract digestibility; GE, gross energy; DM, dry matter; OM, organic matter; CP, crude protein; NDF, neutral detergent fiber; ADF, acid detergent fiber; hemicellulose = NDF−ADF.
