Coated phytase benefits the pig industry

New techniques have been developed to protect phytase enzymes in feed against the detrimental effects of high temperatures during pelleting, but does not limit enzyme release, Canadian research showed.

Cutting-edge “Thermo Protection Technology” which protects phytase from the
adverse effects of high temperatures during feed conditioning and pelleting
represents an exciting step forward for the pig feed industry.

At the
11th Biennial Conference of the Australasian Pig Science Association, Dr
Augustine Owusu-Asiedu of Dansico Animal Nutrition presented a paper entitled
‘Bone mineralization and phosphorus digestibility in weaned pigs fed diets
containing thermostable phytase’.

In this paper he outlined the results
of a trial conducted by the University of Alberta, Canada to determine whether
coating a new-generation bacteria-derived phytase to confer thermostability up
to 90ºC had any detrimental effects on the efficacy of the phytase in the
pig.

In the trial 28 day old male weaned pigs were fed diets reduced in
calcium and phosphorus, and containing either the uncoated or coated
new-generation phytase.

Liveweight gain, feed conversion ratio,
phosphorus digestibility and bone mineralisation were then measured after three
weeks.

No significant differences were found between pigs fed either the
uncoated or the coated phytase, confirming that the coating allows phytase to be
released effectively in the pig’s gut.
