Very good and complete article on mineral nutrition.
Specially the section related to Ca and P and the use of high levels of exogenous phytases.

Very nice article, well done.

Is it just me, but I don't see any Tables to view that are mentioned in the article, if there are some could someone direct myself on how to view them. I have special interest in the calcium and Phos ones.

I have personally seen good results when using a Digestible Calcium: d. Phos model, with higher Phos levels in starter and reduced calcium and Phos levels after day 10, then what is proposed by the breeder companies.
