I'm also researching the nutritional requirements and feeding schedule for quails in different stages in tropics. but I couldn't find. 

Thanks 

There are quite a few recent publications more or less on this topic:

Prof. Antônio Gilberto Bertechini is the mastermind of this group, and they organize the International Symposium on Quail Production, on Brasil, each two years.
