Farmer Jimmy Douglas shelled out 231,000 pounds ($347,000) for the 8-month-old Texel ram called Deveronvale Perfection at an annual sale in Lanark, Scotland.
Douglas says the ram has "a great body and strong loin."
The British Texel Sheep Society says the fee paid Thursday is a world record, eclipsing a 205,00-pound price paid in Australia in 1989.
Society member John Yates says the ram will likely father pedigree lambs worth millions of pounds (dollars) for his new owner.
Breeder Graham Morrison, of Banff, Scotland, says he was staggered by the price but insists Deveronvale Perfection lives up to his name.
