Luciano Andriguetto Protease is used to increase AA digestability (by 3-5% average) in the diet. It is not only SBM. The additional (side) effect is to deactivate tripsin inhibitors if SBM is not enough toasted/too low temperature. For "properly" toasted SBM the additional effect is not required. But protease-exogenous is still active and required for SBM and other proteins sources to increase the ...

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.

Luciano Andriguetto Hi Luciano, The effect of the protease is to improve amino acid digestibility of ingredients, in the presence or absence of trypsin inhibitor. The presence of trysin inhibitor in soybean meal reduces the capacity of the animal to digest protein, and this reduction is partially ameliorated by the protease. Hope this helps!

If we think of a protease being added to the diet to compensate or destroy the anti-trypsin activity of soybean meal, would it be right to say that the net benefit from said protease would be dependent on the quality of the soybean meal (if properly deactivated there is less room for the protease to improve results) or also on the level of inclusion of soybean meal in the diet (if replaced by othe ...

ABSTRACT Enteric infections such as coccidiosis and necrotic enteritis in broilers may have a large influence on the endogenous amino acids (eAA) losses within the gastrointestinal tract (GIT). Although not much is known on this topic, more information is available on the effects of these diseases on the apparent ileal digestibility (AID) of amino acids. There are many factors that must be consid ...

Conclusion The present study conducted at Schothorst Feed Research resulted in an average bioavailability of MHA-FA and diluted DLM65 of 65% and 61%, respectively compared to MetAMINO® considering the overall growth and carcass parameters. These results demonstrate that the relative bioavailability of MHA-FA is significantly lower than its active content of 88% and consistent with the 2018 ...

Interesting article. No doubt enzymes are an important tool in intestinal health. But there is still a long way ahead until we fully understand the complex interactions of all variables, like ingredient composition and its variation, usage of other additives, like organic acids, butyrate, etc, predominant microflora, and others. And this is even worse in swine, where intestinal fermentation can ac ...

Dear All, I would like to add a few comments. If we look at ruminant nutrition, it is very common to analyse NFDN or NIDA, referring to protein associated with cell wall. I understand this explains why proteases yield better results when associated with NSP enzymes, and even phytase. I also understand that the association of proteases is always better than one single protease, as we will have end ...
