I asked a farmer once about if it was possible to switch from cows to bison. he said they need a special fence, because they are so massive (and temperamental) that they will just bust through a normal barbed wire fence. Not sure how true it is but seems plausible. I think he said they need a pen that is dug down, so the bison would have to climb up an incline to reach the fence.
