Phosphorus Problems in the Land of “Perfect” Calcium

It would take me forever to look up references, because I’d have to dig through google/ncbi or research gate and my old research papers from uni for the right sources. This knowledge is second nature to me — I learned it long ago and it’s ingrained from years of working, which helps birds worldwide. For others who only memorized it from a textbook or seminar, or in the lab, finding it again could be a slow process. It’s like asking someone to prove that an umbrella is better than a newspaper for staying dry in the rain — or sneakers are more orthopedic than high heels... you don’t need a study; you’ve lived/learned it.

I originally wrote this for two members who were asking me questions and looking for a specific answer- I figured it there were two people, there may be more in the future. In my mind, it was easier to create an article I could reference later (and easily find again, since I’m still learning how to use the site’s search functions- in which I am enjoying the site).

I’ve done extensive research on vitamin D in birds, and a focus on poultry and passerines (chronic egg layers)- I will try to dig up my old reseach, as the actual requirement might surprise you. I see a lot of inconsistencies online as it is a topic that cannot be explained without regard to variables (even specific breed variations, etc so you cant say '13 hours' or some hogwash like that). If I were to add in the Vit D portion, it would be another couple thousand words. I'm about to get on a plane heading for surgery- so maybe by the end of the month I can add it. :)
