Cows and sunchokes
I haven't tried it on a large scale, but I gave my beef cattle a couple armfuls of Jerusalem Artichoke tops this fall. They liked them very much.
I've also wondered for years if JA's could provide a significant amount of food for pastured pigs. If the pigs move through them quickly enough, and get followed by a good cover crop, I would think the pigs could thin out the tubers enough to keep them from overcrowding. Haven't dared to try any of it yet, though.
