Phytase enzyme: what is next?

//15 Nov 2010

Author: Mojtaba Yegani

There has been a significant increase in the use of phytase enzyme over the past 10-15 years. It is estimated that 60-70% of rations fed to monogastric animals are supplemented with this enzyme.

“First international phytase summit” was the title of a meeting held in Washington, DC in the last week of September 2010. This meeting was organised, in a collaborative effort, by academic and commercial sectors and participants were from different parts of the world.

A wide range of topics including the future of phytase application in the animal feed industry were discussed during this event. Feedback provided by some of the attendees indicated that this gathering was an excellent avenue to discuss and share scientific information on phosphorus- and phytase- related issues from different aspects. The meeting was scheduled to have 5 technical sessions and PDF files of presentations given at each of these sessions are available at the meeting website (www.ips2010.com).

I would like to hear about your practical experiences of using phytase under commercial poultry farm conditions:

I- Do you currently add phytase to your poultry farm rations?

II- Is it being added as a single enzyme or in combination with other enzyme products? 

III- What difference does its supplementation make?

We have a small pig and broiler farm in the Philippines. Phytase was introduced several months ago and has had a very noticable effect on broilers,the pigs having a longer growing period are also now showing promise. We feed Phytase in addition to Xcyanase+Glucanase+Cellulase,these were used several months before Phytase and also gave a marked improvment in growth.
We use acidulated coconut oil (cost) and wondered if there are any comments to be made regarding this? Two other points: is the use of molasses in broiler feeds:currently we add < 1 or 2%.It is produced locally at a very competitive price and wondered if a larger inclusion would be OK ? Lastly Zinc,we would like to know which type to use?

I did my MS project on phytase enzyme production and its application in broiler diets in 1998. The phytase produced (liquid application) was crude in nature and definitely have combination of many enzymes. The way we formulate the diet determine the efficacy of phytase. Corn and wheat based diets would generate better results when phytase is added. However, if grain proportion is low upto only 30% of the diet then it might be costly to use phytase, especially when wheat bran is not the part of diet. In Pakistan commercial feed millers are using phytase enzyme. I would request Dr. Gulraiz Ahmad to please add up to this discussion.

not so much has been said on use of enzymes in tropical conditions (Africa) can someone comment. I would like to do some work on that but i can benefit if someone has tried it

Dear Sir

We are producing 22000 MT Poultry Feed Per Month in Pakistan. We are using Phytase Enzymes for the last 4 years successfully. We can easily replace 0.1% available P by using enzyme. It has positive effect on economics as well on environment. In Pakistan we have gone through series of trial on Phytase enzymes in commercial poultry feeds.
Phytase enzyme can easily be combines with NSP enzymes and work very well . We are using enzyme from Alltech USA which is combination of phytase and nsps and also we are using enzymes from Danisco. Both are working very good.

Thanks and regards
