Dietary xylanase improves growth performance and cost savings in broiler chickens fed a corn-soybean based diet The increased demand to reduce production costs, as well as concerns about the environment, have resulted in pressure on poultry producers to increase dietary energy utilisation and to improve feed efficiency.

Usually, technologies such as exogenous enzymes that are supplemented in the diets have been one of the main pathways used to reach these goals. Xylanase is well known to produce positive effects on growth performance of birds fed diets based on non-starch polysaccharide (NPS) rich cereals, helping the birds to overcome the anti-nutritional effects of NSP by reducing the intestinal viscosity and improving energy digestibility. However, although cornbased diets are widely used in poultry in many regions, there is still a lack of information about the effect of xylanase on this type of diet.

The present xylanase has high activity on the insoluble portion of arabinoxylans, which are present in large quantities in corn and soybean; therefore, it could improve the release of the
