Very good points were raised in this discussion and we see that different approaches are possible. Congrats to all of you. I also would like to add some points that I think we need to take into consideration to better use enzymes: 1-we need to know the amount of antinutritional factors and how they affect each specific feed, for example, soluble Arabinoxylans from one raw material can affect the d ...

Dear Dr. Ivey.It's always a pleasure to read your comments, especially the ones related to the use of mathematical modeling. I do understand (at least I hope) the concept you put forward on how to establish impact of enzymes on individual ingredients' nutritional matrix. I think it might work reasonably well as long as we are dealing with very simple diets. As we increase the number of ingredients ...

It's a shame that there wasn't a treatment with a high level of Cu from sulfate. In this way, the only treatment with a real control diet (with the same Cu and Zn levels from sulfate) is Hyd1.

Dear Dr. Wilkinson. Very interesting material. The variability of limestone in Australia is quite similar to what we see in Brazil, including micro-minerals like iron. One major problem I see with calcium digestibility is how, different form other nutrients, including phosphorus, digestibility is highly influenced by the amount of calcium in a complete feed, as you have mentioned. This is mostly c ...

Dear Dave Albin. I am not sure if I understood your explanation. Could you try to put it in another words? Sorry for my lack of understanding.

Dear Dr. Prasad. I got curious about the maximum energy release of 125-150 kcal/kg, whatever the combination of additives and diet composition. Where does this number comes from?

Very interesting trial. I wonder why the authors didn't analyze the data based on a factorial design with a control diet. Discussion and conclusions would be more simple and direct.

Dear Luis Fernando Luna. Thanks for the explanation and offering. My point is that there are two nutrient releases that have a direct link with performance: Energy (not really a nutrient) and amino acids. There's no way, just based on the performance change, to separate how much of the impact is coming from each one. Throwing everything in only one (f.i., energy), would generate either an over or ...

Dear Luis Fernando Luna. I became curious about your comment on defining matrices for a combination of enzymes based on growth models. Could you elaborate on that? Thank you.

Absolutely, Mike. Even more challenging is the occurrence of epigenetic impacts on the next generation. Lots to understand better in that regard.
