The Field Marshal, a six-year-old Charolais bull, is now 6ft 3in and weighs 3,000lb.
He will not be fully grown until he is eight and is expected to pile on another 650lb in the next year. That will take him past the current British record-holder, his former stablemate The Colonel, who stood 6ft 5in tall and weighed 3,500lb. He died in 2005.
