I found this incident at Vermont College very sad. The sustainable-farming-oriented school planned to slaughter two oxen it's had for years and serve them at the dining hall. Faced with protests from animal rights activists—who successfully prevented the college from finding a willing slaughterhouse—the college ended up having to euthanize one of the animals, who had a bad injury and declining quality of life. As planned, the ox was killed. But nobody got to eat him.
