As I have never been behind the scenes of a rodeo, I cannot give any facts. I would hope that the animals are well taken care of outside of the event. I can't really imagine that a horse or bull would enjoy bucking around like a maniac...though that's a far cry better than horse-tripping *cringe*
I go to CFD every year (I live in the Cheyenne area) and what happens at CFD injury wise could happen every single rodeo I have seen.
The stock is very content, well fed, and love their jobs.
As I said on another thread. The only ones abused/roughed up is the cowboy/girls that compete
