Latest in enzyme technology boosts amino acid digestibility of broiler diets containing up to 18% DDGS.
Broiler producers looking for lower feed costs with distillers dried grains with solubles (DDGS) can use the latest developments in enzyme technology reported Dr David Ledoux at the 2009 International Poultry Scientific Forum, Atlanta, USA, 26-27 January 2009.
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, its use in pig and poultry feed can be limited by the low and often variable digestibility of amino acids and other nutrients in DDGS.
Dr David Ledoux, Professor of Animal Nutrition, University of Missouri, USA, presented a paper "Effects of Avizyme 1500, Phyzyme XP and distillers dried grains with solubles (DDGS) on nutrient digestibility by broilers" which outlined how the latest developments in enzyme technology can improve the nutrient digestibility of broiler diets containing up to 18% DDGS.
The paper summarised a trial where broilers were fed corn soy-based diets containing various levels of DDGS (0%, 6%, 12% and 18%). Diets were either fed without enzyme, or supplemented with a new-generation bacterial phytase (Phyzyme® XP, Danisco Animal Nutrition) with or without a combination of xylanase, amylase and protease enzymes (Avizyme® 1500, Danisco Animal Nutrition). Diets were fed to broilers up to 21 days of age. Feed intake, body weight gain, ileal digestibility and retention of calcium and phosphorus, and ileal amino acid digestibility were measured.
Dr Ledoux concluded that the data indicated that broilers can be fed corn soy diets containing up to 18% DDGS in the starter phase without negatively affecting bodyweight gain and feed conversion.
The important finding of this research was that a combination of phytase, xylanase, amylase and protease enzymes resulted in significantly higher phosphorus and amino acid digestibility, compared to adding only a phytase enzyme to the diet. The substantial improvement in nutrient digestibility from phytase, xylanase, amylase and protease could therefore prove to be a useful tool to reduce feed cost in diets with up to 18% DDGS, resulting in more profit to the producer.

This is an interesting article. Production of ethanol from corn, put a great pressure on demand of corn for animal feed. This increase in demand resulted in significant increae in price of corn and other grains thus increasing the production cost. If DDGS, a by-product of ethanol production, could be used in big quantities in animal feed with the help of enzymes, it will definitely help to reduce the cost of production by replacing valuable grains in animal diet. We must explore the possibilities of usage of DDGS in animal diets in large quantities.
