Danisco Animal Nutrition has recently received the Canadian Feed Industry Association’s (CFIA) approval of its highly thermostable phytase product – Phyzyme XP TPT – into the Canadian livestock feed market.  This event is quite timely in that it offers livestock producers a proven product to help reduce the cost of their feeds in light of the recent increase in feed phosphate prices.

New Thermo Protection Technology (TPT) developed by Danisco ensures that the phytase maintains efficacy after exposure to feed conditioning and pelleting temperatures of up to 95°C (203°F). TPT applies to the phytase enzyme a coating which delivers unrivalled protection from the high temperatures that typically occur during the feed pelleting process, while rapidly releasing the enzyme activity in the animal’s gut, without compromising animal performance.

Independent pelleting trials conducted at Technological Institute, Kolding in Denmark showed consistently high stability after conditioning and pelleting at temperatures up to 95°C (203°F). The thermostable phytase was included in feed prior to conditioning and pelleting at temperatures of 90°C (194°F) or 95ºC (203ºF). The phytase activity present in the feed before and after conditioning/pelleting was analysed and compared. The phytase activity remaining in the feed after conditioning and pelleting was 99% at 90°C and 96% at 95°C when expressed on a relative basis to the unprocessed mash feed.

The trials also compared the thermostability of Phyzyme XP TPT to another commercially available phytase product which is claimed to have similar thermostable properties. In contrast, the corresponding phytase activity remaining in the feed after conditioning/pelleting was 70-75% at 90-95ºC for this product.

 John Van Oort, Canadian Business Manager for Danisco Animal Nutrition, comments that “proven enzyme thermostability remains a key requirement for many of our customers. This patented coating technology delivers a free-flowing, dust-free phytase granulate that can be used easily and confidently in the vast majority of high-temperature feed manufacturing processes in Canada.  Coupled with the leading-edge performance of this new generation phytase feed enzyme, which is proven to deliver at least 20% greater efficacy than traditional phytases, Phyzyme XP TPT offers unrivalled thermostability, performance and value.  Furthermore, this addition to the Phyzyme XP product portfolio gives Danisco Animal Nutrition the most complete selection of phytase products to meet a wide range of feed applications.”

Danisco Animal Nutrition, 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.
