1AFEX = ammonia fiber expansion treatment (30% AFEX straw pellets on a dietary DM basis replacing alfalfa hay pellets).

2Enz− = diet without enzyme.

3Enz+ = diet with enzyme.

4Enz = recombinant fibrolytic enzyme treatment effect (XYL10C, a β-1,4-xylanase, EC 3.2.1.8, GH10 from Aspergillus niger).

a–cWithin a row, means without a common superscript differ (P < 0.05).
