Five breeds were represented in the dairy interbreed on Wednesday with champions from across the Ayrshires, Jerseys, Guernseys, Holsteins and Illawarra's fighting for the top accolade across the Royal Adelaide Show.
Judges from each breed event returned to cast their vote on the best overall exhibit to take out the supreme championship.
They arrived at the decision to crown Holstein cow over six-years-old in milk, Benlargo Elijah Ding, Benlargo Holsteins, Glencoe their supreme champion exhibit.
Jersey judge Ms Hayes said she had a clear winner in the Holstein cow.
"This cow really exemplifies that dairy strength," she said.
"She is long from her nose to her tail, she has a beautiful wedginess to her frame, and she walks on a great set of feet and legs.
"She had an advantage on the texture of her udder and strength of pasterns."
Benlargo's Angela Tweedle said it was "obviously always a dream to win it".
"We've never won it three times so it's pretty exciting," she said.
"It's always a really strong competition here, having the five different breeds and they're always very well represented by each breed.
"I'm hoping that she's in calf again and we can come back next year for our feature breed.
"If not, there's always time to make babies out of her, we'd like to get some more progeny of hers on the ground."
Intermediate supreme was awarded to Lightning Ridge MB Casino Fernleaf 1 ET, Robsvue Holsteins & Jerseys, Moculta.
Mr Walmsley said it was a pretty cool achevement to have won the intermediate supreme with the same cow two years running.
"It's not very common for a cow to be able to do an intermediate two years in a row," he said.
"We have already had people asking us for progeny out of the cow and what we're going to do next.
"I think it's a good legacy for the cow to be able to do that, it might never be achieved for a long time.
"We love her as a cow, just her overall dairy characteristics, the width she has and the capacity she has for Jersey cow."
The Juvenile supreme was awarded to Grantley Sidekick Fifi, Grant Liebelt, Paris Creek.
Mr Liebelt said 40 years ago, the fifth dam back was the supreme champion dairy cow at the Royal Adelaide Show.
"It's an anniversary and it's a bit of a milestone for us and it's really capped it off," he said.
"We dispersed our herd and I've only been too proud to keep it going.
"It has been a real thrill bringing a family member back and to win supreme juvenile.
"Type wise she's a tall, open framed heifer and looked really good at home."
He said it had been a tremendous show.
"It's the best Adelaide show I've seen here for a few years and the quality has been really good," he said.
