Clarence the 'naughty' bull gets TB all clear 16 February 2013 Last updated at 13:46 A bull who faced being put down because he was "too naughty" to let vets near him to test for bovine TB has been given the all clear. Government legislation requires all cattle to be tested. Despite some "thrashing about," Clarence has now been given his jab. Clarence weighs about 600 to 700 kilos (94 to 110 stone). She said she had tried to "make friends" with him after the jab, but he was "not interested." He has four years until his next TB injection test.
