Dr Piotr Stanislawski Uplift in AA digestibility is not increased if protein source already having better digestibility %. But still if you through light on this, will be very pleasureable. Protease also showing negative effect if used in higher dosage or unit values?

Luciano Andriguetto YES, I agree to what you said the biggest advantage of using proteases is to destroy trypsin inhibitors, so whenever you get bad quality soya, you get good results; when you use proteases with good quality soya, we see less results with proteases.

Major problem and point to consider are.
How to control Smell: if go for without coating.
Coating material use: which effect on release.
heavy metals sometimes get in analysis:
Ca or Na Butyrate: Still no exact clarification.
Definitely Price is another issue.

Excellent article,covering in quite simply way all aspects of phytates /phytase /phosphorus.
I like it very much. Just some additional words.
1.phytase unit: there is more than one unit name and value.The registration conditions (eg.pH 5,5, temp 37C, 1 min....) are same but other factors (the buffer, colorant, etc in lab conditions) are different. Eg.one unit FTU (Du Pont) is not equall to FYT (DS ...

In my opinion, specific enzyme like protease should be as homologous as endogenous enzymes hence enzyme can work with more efficacy on protein raw materials which we are using in poultry feed and also should act on broad ph level, hence acceleration rate can increase with more contact time of enzyme and substrate and finally all applications should be cost effective.

Steffen Hansen , I agree with your points, but still if you see many product having combination of all 3 types of protease and by comparing the field results also they shown a good result compared with single protease compound..

Dr. Vijay Swami, It´s the other way around. You choose an enzyme based on the raw materials that are in the feed. If you already have dipeptides in the GI tract the need for proteases is small.
Alkaline proteases should be avoided. Theses proteases are most likely developed for detergents not for animal feed. The efficacy of an enzyme is to a large degree determined by it´s optimum pH level. In ...

dr Piotr Stanislawski , thanks for your suggestion, other than serine protease, which other active center will be helpful. Like metalloprotinease or carboxyl protease. Can u explain on this please. Please put you valuable opinion on this..

Dr. Vijay Swami I'm a bit late; Steffen Hansen explanation is almost sufficient.Some additional words; I work with serine endoprotease (ProAct) which is less specific protease,working on protein chain with preference for hydrophobic AA (eg. Cys, Leu, Tyr, Ile) and supporting more specific endoprotease like Trypsine (preference for Arg, Lys). "Together" they can do more and make the protein more d ...

dr Piotr Stanislawski I want to know what is best combination percentage for acidic, neutral and alkaline protease. In the defination of protease which substrate is best, pure protein or dipeptide?
