Interesting discussion. What is your recommended method for determination of solubility of the fiber fractions? And shouldn´t we also be concerned about the amount of nitrogen bound to fiber, as it will affect the microbiota in birds and pigs?

No common feedstuff is 100% digested. In practice, 10-15% are excreted in faeces without bringing any means to bird requirement and in addition cause potential anti-nutritional effects. Thus, there is no doubt poultry benefits the most from use of exogenous enzymes and is becoming a norm to utilize the undigested parts and to overcome the adverse effects as well. However, the biological reality is ...

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 ...

ABSTRACTEnteric 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 consider ...

ConclusionThe 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 EFSA ...

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 ...
