PEG, polyethylene glycol; PEG(−), denotes presence of tannin; PEG(+), denotes absence of tannin; SEM, standard error of the mean.

b, gas production from the insoluble but slowly fermentable/degradable fraction (mL).

C, the rate of GP from insoluble fraction per hour.

PD, potential gas production (mL).

Means with different superscript (letters) across the column for each parameter are significantly (p<0.05) different.
