As is this question has yet to be tackled so I'm taking a stab at it. Like you (or so I'm gathering) I like clear facts and scientific proof for all things medical. My back ground is veterinary medicine however this DOES NOT make me a Veterinarian but an able researcher of medical journals. A quick search and this is what I have gathered for you...
Ca:P ratios are typically calculated and tested in performance/growth/production studies. I have learned from my undergrad that Ca:P tend to be fairly close from species to species but like all thing natural there are exceptions to the rule. For example:
In
Cows: "ratios between 1:1 and 7:1 gave similar and satisfactory results."
In
humans "The 1.7:1 ratio allowed for the highest absolute retention of both minerals"
While Calcium and Phosphorous are vital nutrients of most all living animals, including humans, debateably their most important role is played in bone mineralization and mineral retention and there for greatly studied as such (their functions are by no means limits to just the mentioned above.
I have tried to find a medical journal with a Glider specific article that I could link here for you. This is the best I could do:
Journal of Exotic Pet Medicine Which at least gives the bibliographic information and abstract. Access to the article would require a trip to the library to inquire about this issue- Sorry.
I hope this helps.
