I'm writing a university paper on donkeys for the collection of milk. I had some problems finding information about sizing de facilities, sizing of different pens for animals according to the stage of their reproductive cycle as maternity, park droughts donkeys, waiting room, milking room, among others. I have also had difficulty in knowing what materials should be used in the construction of the milking room, the milk storage room, etc.
If anyone could help me in the design of such facilities for such production I would be grateful
