Novel phytase profits DDGS fed animals
Pig and poultry producers looking for lower feed costs with distillers dried
grains with solubles (DDGS) can use the latest developments in enzyme technology
reported Dr Alexandre Péron at the 42nd University of Nottingham Feed
Conference, UK, 3-4 September 2008.
As feed costs continue to escalate, by-products from the food and fuel
ethanol industries can provide alternative, more cost- effective ingredient
options for the nutritionist. The use of DDGS in animal feed has increased with
the growth of the bioethanol industry. Whilst DDGS is potentially a cost
effective and valuable feed ingredient, there are certain anti-nutritional
factors which can limit its use in pig and poultry feed.
Dr Alexandre Péron, Technical
Services Manager, Danisco Animal Nutrition, presented two posters which outlined
how the latest developments in enzyme technology can improve the nutrient
digestibility of pig and poultry diets containing
A trial conducted by Auburn
University, USA, showed that adding both a new-generation bacterial phytase
(Phyzyme® XP) together with xylanase, amylase and protease enzymes (Avizyme®
1502) to corn-soy based broiler diets containing 10% corn DDGS improved
bodyweight gain by 5-12% and feed efficiency by
Similarly in pigs, a trial showed that
adding both the new-generation phytase (Phyzyme® XP) together with a highly
effective xylanase (Porzyme® 9300) to a corn-soy based diet containing 20% corn
DDGS significantly improved digestible energy by 5.6% (175 kcal/kg, 0.73 MJ/kg),
ileal amino acid digestibility by 4-8% and increased phosphorus digestibility
from 22% to 51%.
