In vitro digestibility of brewers’ spent grain and residues treated by proteases varying with dosages. a-c Means with different letters with the same dose of enzyme are different (P < 0.05). BSG, brewers’ spent grain; AL, EL, FL are linear and AQ, EQ, FQ are quadratic effects, respectively, for alcalase, everlase and flavouezyme dose (enzyme:protein, w/w; 1:100, 5:100, 10:100 and 15:100, respectively for Low, Med, MedH and High). All enzyme × enzyme dosage and the contrasts between the average of 4 doses of each enzyme and BSG were significant (P < 0.01). The enzyme effects were P < 0.01, P < 0.38, P < 0.18 and P < 0.01 for Figure a, b, c and d, respectively
