Advances in mass animal deaths: 200 dead cows in Wisconsin

The latest in a bizarre series of animal deaths occurred on January 14. The Wisconsin Rapids Tribune reported that the Portage County Sheriff's Department dispatched police to the town of Stockton after a cattle owner discovered "numerous dead cows" in a field.

The owner, whose name has been withheld by authorities, told deputies that he suspected the animals died of IBR (infectious bovine rhinotracheitis), a respiratory condition, or BVD (bovine virus diarrhea), an illness that can damage a cow's digestive and immune systems, lead to pneumonia and kill unborn calves. Authorities have sent samples from the cow corpses to Madison to determine the exact cause of death.
