Animal welfare group's video shows Ohio cows beaten with crowbars, stabbed with pitchforks Meghan Barr, Associated Press Writer, On Tuesday May 25, 2010, 8:36 pm EDT CLEVELAND (AP) -- Graphic video released to The Associated Press by an animal welfare group shows workers at an Ohio dairy farm beating cows with crowbars, stabbing them with pitchforks and punching them in their heads. The Chicago-based nonprofit group Mercy For Animals says the video was recorded in an undercover investigation at Conklin Dairy Farms Inc. The Plain City, Ohio-based dairy farm hasn't responded to a request for comment left Tuesday. Mercy For Animals publicizes what it calls cruel practices in the dairy, meat and egg industries and promotes a vegan diet. The video shows workers holding newborn calves down and stomping on their heads. It also shows one worker wiring a cow's nose to a metal bar near the ground and repeatedly beating it with a bar while it bleeds.
