SEM = standard error of the mean.

^{a, b} Mean values within a row with different superscripts were significantly different (P < 0.05).

¹Reported values are least-squares means.

²The basal diets were supplemented with or without 75 mg/kg of 1 of 5 types of xylanase supplements (xylanase A [XA], xylanase B [XB], xylanase C [XC], xylanase D [XD], and xylanase E [XE]) from various original microorganisms.
