Sam, we feed cake to our cows too. Dad would usually buy 3 or 4 tons of it. Before we fed it, we would empty a sack into a sifter box, and sift any powder out of it and sack it up in flour sacks. He used this to feed sick cows and calves. .
Oh yeah, save the dust and crumbs!
We mix in 3/16"s pellets for the feed yard ration.
