Blosom stood at a staggering 74.8 inches and was first recognised as the tallest cow living after Guinness World Records visited Blosom and her owner in Orangeville, Illinois, earlier this year.
The 13-year-old female Holstein passed away last month after sustaining an irreparable leg injury. Following further research, Guinness World Records has confirmed that Blosom is now recognised as the title holder for Tallest Cow ever.
The previous record holder for the tallest cow ever was Mount Katahdin, a Holstein-Durham cross who, from 1906-1910, stood at nearly 6 feet 2 inches to the shoulder and had a girth measuring 13 feet.
On learning about Blosom's latest record her owner Patty Meads-Hanson said, "The funny thing about Blosom was how unaffected she was by all the attention that seemed to surround her."
"As long as she had her oats, and daily chin rubs and ear scratches, life was good," Meads-Hanson said.
"We hold our tallest animals at Guinness World Records in an extremely high regard due to their uniqueness and rarity in finding," said Guinness World Records Editor-in Chief, Craig Glenday.
"We were devastated when we heard the news of Blosom's death as she was such a friendly and gorgeous animal and her owner equally as wonderful and took such great care of her," said Glenday.
