I don't know anything about 52 varieties but I do know the free-range, organically-fed (meaning they roam people's gardens and eat what they please including magic mushrooms) local ones like to breed in my garden. They make a lot of noise at it too. And when they get old they get butchered by men with machetes and no idea of how to cut a fillet steak but still, its really great the cows lived how they pleased.
I'm watching Bizarre Foods-Jamaica right now. The guy is talking about how chicken and bull-foot soup with pieces of cow skin is a perfect marriage of collagen and fat and just delicious. I'd rather have the cows in the garden, screwing noisily, stoned on magic mushrooms than in a pot.
