Extract

Enhanced nutrient digestion and absorption in enzyme supplemented broiler diets could be either through reduced digesta viscosity or weakening of the cage effect elicited by soluble or insoluble Non – Starch – Polysaccharides (NSP) on nutrient digestion and absorption. Inhibitory effect of insoluble NSP on endogenous protease reduces efficient digestion of nutrients embedded in cell wall matrix of grains. Increased amount of undigested and unabsorbed protein reaching the caecum implies available nutrient for fermentation and increased coliform forming units of such bacteria as clostridium that ferment proteins, peptides and amino acids. The study aimed to assess the effect of partial replacement of maize with Rice Husk (RH) supplemented with Roxazyme G2 G enzyme on ileal crude protein digestibility, caecal crude protein retention and digesta viscosity in broilers.
