Wet bag of feed...

I bought a 25lb bag of layer crumble from one of my usual feed stores. When I got it home and opened it I noticed that it was not crumbles but mash and some of it was a little wet and some had mold on it. Now, I know that I got a discount on the bag, because my daughter was with me (she likes the cowboy/fireman calendar look) and that's who works at the feed place. So we BOTH return to the store, and the Hot cowguy (her words ) said no problem and brought us a 50lb bag of crumbles to replace the wet bag, at no extra charge (again, thanks daughter ) and he let me keep the mash.

But here is my question, can I use the mash in any way?
