I have cow pies galore in the pasture and even though they look "dry", that can be deceiving....they look crusty on the outside but warm and oozy in the middle--just like a pie!
Anyway, I have never added uncomposted cow manure to my garden, it needs to "break down" for a while. It could burn plants and more importantly who wants fresh poop of any kind in your garden. I am always "pinging" my cats out of the garden with my bb gun when they dig out my new rows of seeds to go to the bathroom. I don't like the idea of digging in that crap.
Get your bucket of pies and throw them in a corner somewhere or a compost bin and let them break down, mix them with leaves and grass, THEN put them in whatever you want to fertilize.
