I don't read the labels...I assume it does not matter. It's the fat content that I am trying to provide to the nursing mothers (so that they don't have to cannibalize the kits). I continue to get big plump litters until the dams are too old...then the numbers produced by that particular dam decrease...
I could be waaay off but this works for me, so I see no reason to change it, and I'd be happy to show pics of my litters of rats and mice anytime.![]()
