From: Feed nutritional value of brewers’ spent grain residue resulting from protease aided protein removal
Asymptotic gas volume (mL/g DM; a) and gas production rate (%/h; b) of brewers’ spent grain and residues treated by proteases varying with dosages. a-cMeans with different letters in the same dose are different (P < 0.05). BSG, brewers’ spent grain; Pen, enzyme effects; PInt, interaction between enzyme and enzyme dosage; PAL, PEL, PFL are linear and PAQ, PEQ, PFQ are quadratic effects of, respectively, 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); PBR, contrast between average of 4 doses of each enzyme and BSG
