Enzyme technology boosts performance of broilers fed DDGS

Broiler producers looking for lower feed costs with DDGS can save around $9/tonne, without risking bird performance, according to the latest research from Danisco Animal Nutrition.

Two trials conducted by Auburn University and Purdue University, USA, showed that adding both a new-generation phytase (Phyzyme® XP) together with xylanase, amylase and protease enzymes (Avizyme® 1502) to corn soy broiler diets containing 10% corn DDGS improved bodyweight gain and feed efficiency. Bodyweight gain was improved by around 5-8% and feed conversion improved by up to 11 points (6%).

In the trial conducted by Auburn University, the enzyme combination was also added to a lower cost diet reduced in energy by 80 kcals/kg feed and containing 0.1% lower available phosphorus and lower calcium. At 56 days of age, broiler liveweight gain was significantly better (8%) and feed conversion numerically improved (4 points) compared to broilers fed a standard corn soy diet containing 10% corn DDGS.

“Feed prices are at an all time high. Now, more than ever, poultry producers need to exploit technologies available to them to maximise margins,” explains Dr Milan Hruby, Regional Technical Services Manager - USA and Canada.

“Using enzyme technology, broiler producers have the opportunity to reformulate diets with lower energy, phosphorus and calcium levels and also include some DDGS in their formulations to further reduce feed costs. In the trial conducted at Auburn University, gross feed cost savings of over $9/tonne were achieved,” Dr Hruby concludes.
