A beneficiary gifts catalogue is hoping to score a hit with people looking for unusual Christmas gift ideas.
The Charities Advisory Trust's Good Gifts catalogue is offering a single shot of prize bull semen for £10 to help increase cattle numbers on a farm project in Rwanda.
The trust describes the donation as "a gift loaded with potential".
Good Gifts bought Sid, a prize bull costing £1,200, for the Surf Survivors Fund, which runs the farm.
"It is very difficult for him to get the cows pregnant because they are fertile for only one day a month," said Hilary Blume, director of the Charities Advisory Trust. "The veterinary service has more success with artificial insemination."
Because a single bull is able to impregnate thousands of cows, the service will allow the farm to increase numbers in its herd without exhausting Sid.
Other new gifts from this year's catalogue include a knitting pattern for a jacket to keep a penguin safe after an oil slick for £12, and the chance to support an Iraqi child for two months at £50.
