It's call krunch horse ration. Where I live they don't make rodent food and the hog grower oout here is way to small for a rack. Anyways back to the feed.

16% crude protein
4% crude fat
9% crude fiber
.75 calcium
.50 prosphoeus

im not sure what its made out of they said its made out if a bunch if different stuff ad would work for mice, I'm just curios is it safe for my mice and will they still breed and do there thing fine on this feed or should I try to find something new?
