It takes two horses to carry a bull out. The only bone we leave in is the femurs. A horse can carry a three hundred pound man pretty well. But 200 lb of dead weight on a pack saddle is a pretty hard and fast rule. Unless you are packing on a Belgian, I suppose. Never saw anybody try that.
She's not a Belgian, but my Percheron cross has carried a few bulls out in one trip. 4 quarters, tender loins, back straps, and horns. Bone in. Doesn't seem to even be a little bit of an issue. I guess none of them were the World's biggest bulls. One was my busted up 6 point from this fall. There are actually quite a few drafts and draft crosses being used to ride and pack or both like mine. Crosses are kind of a fad right now, but outfitters have been using them for years.
I've packed more than a few loads on full percherons. Only real issue is I'm 5'9" and the tops of those loads is a lot higher than that.
I'd rather have two for it but one if big enough and in shape can and does do the job.
