Values are the mean of eight replicates per treatment.
CON, control diet; CON-X, CON + 3,000 U/kg xylanase; L-X, corn replaced to 2% wheat bran in CON + 3,000 U/kg xylanase; M-X, corn replaced to 4% wheat bran in CON + 3,000 U/kg xylanase; H-X, corn replaced to 8% wheat bran in CON+ 3,000 U/kg xylanase.
Pooled standard error of the mean.
Values in a row with different superscripts differ significantly (p < 0.05).
