Effects of supplemental β-mannanase on in vitro disappearance of dry matter in feed ingredients for swine

The present study was aimed to investigate the effects of supplemental β-mannanase on in vitro ileal disappearance (IVID) and total tract (IVTTD) dry matter (DM) barley, canola meal, copra corn, corn distillers dried grains with solubles, cottonseed palm kernel soybean wheat for pigs. Feed ingredient samples were finely ground divided into control group treatment group. prepared contain 990 g/kg test 10 cornstarch, whereas product (8,000 units/kg mixed sample). A 2-step digestion technique, which simulated absorption processes stomach small intestine, used determine IVID DM ingredients, a 3-step additionally process large IVTTD ingredients. procedures performed triplicate each sample. addition increased (p = 0.003) tended increase 0.063) meal. meal improved < 0.05) by β-mannanase. In conclusion, digestibility nutrients pigs may be when is added diets containing or wheat.
