Enzyme technology significantly improves DDGS Digestibility

US - Pig producers looking to reduce feed costs by including DDGS in the feed formulation can use the latest developments in enzyme technology to improve nutrient digestibility,

Recent research from Danisco Animal Nutrition shows that although DDGS are highly fibrous and can be highly variable in nutrient availability, they can be useful in diet inclusions if they are managed carefully.

A trial conducted by the University of Illinois, USA, showed that adding both a new-generation phytase (Phyzyme® XP) together with a highly effective xylanase (Porzyme® 9300) to a corn-soy pig diet containing 20 percent corn DDGS significantly improved digestible energy by 5.6 percent (175 kcal/kg), ileal amino acid digestibility by around 4.5 percent and increased phosphorus digestibility from 22 percent to 51 percent.

“While DDGS are potentially a cost-effective and valuable feed ingredient, there are certain anti-nutritional factors which can limit its use in pig feed. We have a wealth of data to show that adding our specific xylanase to pig feeds containing highly fibrous grain by-products improves energy and nutrient digestibility and subsequent pig performance," explains Dr Gary Partridge, Technical Services Director, Danisco Animal Nutrition.

In the Illinois trial, adding xylanase together with a new generation phytase further improved nutrient digestibility compared to adding either xylanase or phytase individually.

“With feed prices at an all time high. Now, more than ever, pig producers need to exploit technologies available to them to maximise margins,” said Dr Partridge.
