Popis: Background: Alternative feed ingredients are widely used in swine diets to lower feed costs, but these ingredients contain a large quantity of non-starch polysaccharides. Supplemental xylanase is known to break down non-starch polysaccharides. However, the effects of exogenous xylanase from Bacillus subtilis on various feed ingredients have rarely been compared. Objective: To evaluate the effects of supplemental xylanase on in vitro disappearance of dry matter (DM) in various feed ingredients for pigs. Methods: Nine feed ingredients were used to measure in vitro ileal disappearance and in vitro total tract disappearance of DM. Each ground ingredient was supplemented with either supplemental xylanase (9,000 U/g) or cornstarch at 1.0%. Results: Supplemental xylanase increased in vitro ileal disappearance of DM in wheat, barley, wheat flour, and wheat bran (p
