Hello again. Respecting all opinions, from my experience, I would certainly use a tot Ca value as a matrix - the phytase has an sparing effect of Ca by avoiding its chelation to the phytate-, but then for the rest of the ingredients I would add to the existing tot Ca, a new value - identical to the total Ca-, called "label", "analytical"..., you name it. After the LCF exercise, you´ll get the solu ...

Hello. Any nutrient defined as digestible is, in principle, potentially of use to the animal. Total has much less meaning vs digestible from the nutritive stand point.

Hello there. Mick´s comments are, to me, absolutely correct! Phytases do have an effect in making tot Ca of the diet more available to the bird. But to reflect this effect correctly without making mistakes in what real Ca can be measured in your feed, then use 2 Ca values for each ingredient: Ca analytical - I call it Ca label - and tot Ca (biological by Mick). However, for the phytase, just ...

Aaron, I found your comment absolutely key; we, so many times get tied to endless discussions on which should be the level of enzyme addition without paying attention to the amount of potentially reactive substrate. Thanks and take care. Rafa.

Silvia, many thanks for answering my questions in such short period - believe me when I say at times questions are not answered -. They are very clear and helped me getting the concept of your protease and what to expect when it is combined either with carbohydrase and/or with a phytase. Interesting point as well that one of the intestinal health. Take care during your next trips!

Dear Rahat, in case you'd like to know more about what you ask, then there is a need of a F2F meeting or a more detailed conversation. Are you by any means in the area of any DuPont office? At least I would say there is a clear relationship enzyme dosage substrate when it comes to the phytase. Cheers.

Hello from Colmenar Viejo, Madrid, Spain. Thanks for your short but clear presentation Silvia, very interesting. My questions to you are: i) would Cibenza EP150 replace, in a mixed- grains, vegetable proteins- type of diet for broilers the rest of the normally used carbohidrases?; ii) in case you believe they both have to be used, would they have additive or even synergetic effect?; iii) is your p ...

Hello there, it's been a long time since the last time I wrote.........thanks for the short paper on CP in piglet diets. My question here would be: you are recommending a CP reduction in PW diets, but to what level would you say, in the very first diet and don´t you think using high CP of very good quality proteins at least 1-2 weeks would help the young animals, so that they, with next diet ...

Very interesting Jerry. You mentioned the E content is same as corn; we formulate here in EU mostly with NE, not ME, could you underline if ME/NE wise still E content is equal or less in the second case due to high CP, high NDF content? And, in case is not too much asking: any comment on your experiences in the US with corn DDGS in both pregnant and lactating sows. Highly appreciate your answers, ...

Many thanks Mike, great to know. I like when I see I know so little after all these years, so that I keep learning. Cheers from Colmenar Viejo, Spain.
