Dear Gemma González Ortiz, yes your are right but we can get 1+1+1=3, if we supplement enzymes with their best, and the enzymes best is to provide enough room(substrate) to enzymes. Moreover, enzymes are meant to be cost saving with sustaining performance of birds. i suggest we should follow the bell shaped curve for enzymes. reducing the nutrient specs of feed, supplement the enzymes you will not ...

A work published in 2017 (Santos et al., 2017) http://dx.doi.org/10.1016/j.aninu.2017.02.001 showed there is no additivity in the combination of phytase superdosing, xylanase and protease. Something to take into account when formulating diets and accept that having more enzymes in the formula does not mean they are going to work with the same efficiency. There is a nutrient limitation as key nutri ...

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!

Hello all,From the point of view of enzyme activities, the standard measure is how many moles of the product (the result of the chemical reaction) is released by a specific amount of the enzyme during a specific time and pH conditions. Although I am a biotechnologist I have worked in the animal industry and know that information does not translate well with industrial enzyme users. However, in the ...

Lode Nollet that is precisely my point. An FTU is a totally useless measurement of how one phytase may compare to another. we have run numerous trials with different phytases and have often reported this.

Hi RafaelGreat to hear from you and yes it is a long time!. You make an interesting point. Quantitatively the most untapped but potentially fermentable fibre source in the maturing bird (>14d of age) is xylan and to a lesser extent glucan. I used to think that the enzymes we were feeding quantitatively produced the prebiotics which were fermented in the caeca to offset the protein as discussed. ...
