Xylanase in corn-based pig finisher diets
With feed making up 70% of the production costs in swine, technologies that can effectively improve feed efficiency are still a focus for producers targeting a lower overall cost of production. Fibre-degrading enzymes have been extensively used in broilers in both non-viscous and viscous diets, and are becoming more of a focus for pig producers in corn-based rations. It is understood that fibre-degrading enzymes increase nutrient digestion and consequently animal performance.
The application of fibre-degrading enzymes of -- which xylanases are the most commonly used and efficacious -- has also tended to focus primarily on pig diets containing viscous grains, such as wheat and barley. This in part may be attributed to the understanding that the addition of xylanases reduces the impact of viscosity in the pig gut and that increased viscosity is more typical with barley and wheat, but not corn.
However, new research has shown a six point improvement in FCRc (weight corrected) in finisher pigs fed corn-based diets supplemented with a single xylanase, Econase XT.
