¹ n = 15 pigs per treatment per treatment-fed experimental diets for a 36-d adaptation period followed by a 10-d metabolism crate study.

²Dietary treatments include: LF, basal corn-soybean diet; HF, basal corn-soybean diet with 30% corn bran at the expense of corn; HF with the addition of xylanase (HF + XY); HF with the addition of AXOS (HF + AX).

³Viscosity values are the intercept of the exponential relationship of the observed shear-thinning behavior for a given sample measured a six shear force rates.

^a,b,cWithin a row, means without a common superscript differ (P ≤ 0.05).
