Danisco's research on coated phytase excites feed industry
 

Press release
 

 

Cutting-edge 'Thermo Protection Technology' that protects phytase from the adverse effects of high temperatures during feed conditioning and pelleting represents an exciting step forward for the feed industry, scientists from Danisco Animal Nutrition told delegates at the 2007 International Poultry Scientific Forum in Georgia, US.

 

Presenting a poster titled 'The effect of a new coating on the thermotolerance of a phytase product', Dr Soren Dalsgaard, a senior scientist with Danisco, explained that trials with the new technology being developed by Danisco Animal Nutrition have clearly demonstrated its ability to provide unrivalled protection from high processing temperatures, ensuring that both the enzyme's efficacy and its beneficial effects on animal performance are maintained.

 

Independent trials conducted by the Technological Institute at Kolding in Denmark to investigate the technology's effect on the thermostability of Danisco's new-generation phytase Phyzyme XP showed that it produced consistently good results.

 

Thermo Protection Technology involves applying a coating to the phytase. The coated phytase was included in the feed prior to conditioning and pelleting at temperatures of 90 deg C (194ºF) or 95 deg C (203ºF).

 

Analysis showed that, relative to unprocessed mash feed, 99 percent of the phytase activity remained after conditioning and pelleting at 90 deg C, while at 95 deg C, 96 percent of the phytase activity remained. This compared with 75 percent activity at 90 deg C and 66 percent activity at 95 deg C for another commercially available phytase product that claimed to have similar thermostable properties.

 

In a paper titled 'The effect of a new coating on thermotolerance and bioefficacy of a phytase product in broilers fed corn-soybean meal-based diets', Dr Janet Remus, Technical Services Manager for Danisco Animal Nutrition, outlined the results of trials conducted by ADAS in the UK to determine whether coating the new-generation phytase to confer thermostability up to 95 deg C had any detrimental effects on phytase efficacy in the animal.

 

Broilers were fed diets containing either the uncoated or coated new-generation phytase. Liveweight gain, feed conversion ratio (FCR) and tibia ash were then measured. No significant differences were found between broilers fed either the uncoated or the coated phytase, confirming that the coating allowed phytase to be released effectively in the bird's gut. 

 

Danisco Animal Nutrition (www.danisco.com/animalnutrition), a business unit of leading global food ingredient specialist Danisco A/S (Denmark), pioneered the development and use of enzymes and betaine in animal nutrition. Its products are now widely used by poultry and pig producers throughout the world. The company's mission is to deliver innovative, sustainable solutions that increase efficiency and safety of the food production chain in an environmentally sensitive way.
