Video footage released by an animal rights activist shows cows at a Shropshire dairy farm that supplies a large multinational company being hit, punched and kicked. <br /><br />The shocking footage was shot at Heaths of Stockton at Stockton Grange Farm, near Newport, which supplies German-based international dairy firm Muller. <br /><br />The secretly recorded video, which activists claim was shot earlier this year, shows workers at the dairy plant roughly handling the dairy cows at the site. <br /><br />In one part of the video, which was recorded by hidden cameras, a worker can be seen dragging a calf across a floor and even through the bars of a metal gate, while kicking its anxious mother. <br /><br />Video: Joey Carbstrong
