High Park Lady, a 25-year-old thoroughbred mare, may be the oldest mare to ever be successfully foaled.
She has been entered to the Guinness Book of Records as a result, after becoming pregnant earlier this month.
Thoroughbred mares usually stop foaling between 21 and 22 years of age. High Park Lady was given a thorough health check by Oakham Vets before the decision was made to cover her.
Sarah Waring, who runs a thoroughbred stud at Stibbington House in Wansford, said: “She looks tremendous and belies her age.”
High Park Lady has been foaled to Beat All, a versatile dual purpose stallion who came third in the 2013 Derby and has had wins on flats, jumps and in point-to-point races.
Beat All already has a book of mares to be covered next season.
Mrs Waring has high expectations for the new foal. She hopes that trainer Nicky Henderson will take it on as he has with two of Beat All’s previous offspring.
Mrs Waring added: “I would like to thank Oakham Vets for all their help with the mares at the Stud this season, especially Vicki Marchi who was instrumental in getting High park to conceive.
“She went above and beyond the normal level of service. I never dreamed High Park Lady would become pregnant.”
The new foal, which is due to be born in May 2016, will be submitted to Weatherbys register of horse names.
