Regarding Barbaro, I believe it was an injury that wouldn't heal properly and then infection set in and wouldn't let go. They had to put him down.
PETA and all the rest of the animal rights nuts are only in it for themselves. They refuse to accept the fact that humans are meat eaters (incisor teeth and one stomache) and That there is a thing such as compromise. Same as the Abortion wackos - its ok to kill a doctor but don't touch that fetus!
I'm in the biz and work with these crazies every day. What kills me is I have yet to meet an underweight vegan and they almost all are rabbit food eaters.
Can't wait until science proves that plants have feelings.
