It's just a bunch of crap pressed in to a large pellet.
The short story:
My mother in law has been poorly for about a month. My wife has been staying with her. Between work, and keeping things up on the farm, and being Mr. Mom--------I had to turn my fall Calvers , spring calvers, and bred heifers all in together. It just made feeding hay so much simpler. The spring herd/some bred heifers could calve as early as the 22nd. I need to get several sorted off. Everything has free run of the place. I thought if these things are really like crack then I'd give em a try. I put a 50 pound bag out in close proximity to the herd. A few came and ate. It doesn't draw them as well as my stocker mix. You just don't do good pouring that stuff on the ground. Everything can calve were its at, that's just not my normal way, and a monumental task to check everyday once the deed starts going down.
