No, they're Plains Buffalo. We're going for meat animals, not tough old trophy bulls. Bison is superb eating, very lean, like deer or elk, and flavourful like Black Angus. It needs to be cooked like game meat, medium is perfect.
I specifically said “not necessarily” because while in most cases what you are saying is absolutely true, when we put down my wife’s Morgan/Quarter gelding last Spring, it was the second time he’d seen a vet in the 12 years we’d been together. $50 a month for feet trimming and no more than $500 a year in hay is what he cost me. Of course there had been a few more minor expenses than that, but they never added up to anything significant.
