The mean values of in vivo DM (0.633) and OM (0.685) digestibility of the straw treated
with WAE observed in the present study were higher than those treated with NaOH (0.617
and 0.637, respectively) at similar alkalinity strength, reported by Sundstøl (1981). Higher
values of DM, OM, NDF and ADF digestibility of wheat straw treated with WAE than those
treated with NaOH have been reported
