Means values within a row with different letters differ significantly (P < 0.05).
Only bacterial genera (accounted for ≥0.1% in at least one of the samples) that affected by treatments were listed.
CON, control diet; HG, high grain diet; HG+T, high grain diet supplemented with 180 mg thiamine/kg DMI.
SEM, standard error of the mean.
