Comparison of enzymatic hydrolysis effects of Aspergillus niger derived xylanase EX1 on different feed ingredients, determined by the release of reducing sugars (RS) and the improvement of in vitro dry matter digestibility (IVDMD). (A,B) Corn–soybean meal basal substrates mixed with 5% DDGS; (C,D) unitary corn hull (CH) substrate; (E,F) unitary wheat bran (WB) substrate; (G,H) comparison of the net increase in RS release (ΔRS, mg/g) and dry matter digestibility (ΔIVDMD, %), respectively. Polylines directly explain the actual variability of each indicator. The dark brown curves in scatter plots display the RS trend, while the light blue represents the fit of IVDMD. The data are expressed as the means ± SD.
