Big Bertha (17 March 1945 – 31 December 1993) was a cow who held two Guinness World Records: she was the oldest cow recorded, dying just three months short of her 49th birthday, and she also held the record for lifetime breeding, having produced 39 calves
Bertha, or ‘Big Bertha’ as she was known, was a legendary Droimeann cow from Sneem in Co. Kerry. She was reared locally, and was bought as a calf by a farmer called Jerome O’Leary.
When she died on New Year’s Eve 1993, just 3 months shy of her 49th birthday, she had become something of a local celebrity. Over the course of her long life she had given birth to 39 calves, and this achievement, together with her tremendous age, had earned her an entry in the Guinness Book of Records. This fame was harnessed productively by Mr. O’Leary; Bertha became a regular at local fairs, and lead the annual St. Patrick’s Day parade in Sneem where she was engaged in raising money for local cancer relief charities.
