Tandara Brown Swiss stud, Dingee, Vic, again produced the goods at International Dairy Week Brown Swiss Show on Tuesday.
The stud took the grand champion, senior champion and intermediate champion cow awards, and also bred the junior champion cow.
The grand champion was the intermediate champion Tandara Bosephus Sarajevo 121, owned by Tandara in conjunction with Jayden Drake.
Tandara's Ben Govett said the cow from their successful Sarajevo family had turned heads at IDW last year.
"We thought she was pretty special - she's got a lot of admirers from all over the world," he said.
"And this year she has developed so much; she's probably the most exciting young cow we've ever had, that's for sure."
The three-year-old cow was on its second calf and was a big cow that produced a lot of milk.

Judge David Mayo, Gerringong, NSW, said the intermediate cow, which he also awarded the best udder award, had a bright future.
"This young cow is a tremendous young cow when you get up close to her," he said.
"She's a really good long dairy cow with lots of strength in her front end, the openess, the strength and the dairyness."
Part-owner Jayden Drake said he was over the moon with the win.
Mr Drake said he had helped Mr Govett at IDW for 10 years and had shown a few animals, but had never enjoyed the success of an IDW championship before.
Mr Govett bought the senior champion Miss Payssli Lola as a calf from his friends Kelvin and Ronnie Cochrane, Gympie, Qld.
The five-year-old cow's mother was a Queensland champion, and Mr Govett said when the opportunity came up to buy its calf, it was too good to miss.
Miss Payssli Lola had won her class three times at previous IDW shows, slowly building to the champion ranking, Mr Govett said.
He said the cow was the type they aimed to breed: it got in calf every year, had above average production and had never been sick.
The Brown Swiss were a fantastic breed for Austalian conditions with heat tolerance, longevity and hardiness.
Mr Govett said he was "pretty excited" to have been associated with all three champions.
"It's been a goal to do it one day but things don't always line up," he said.
He congratulated the owners of the junior champion Cameron and Tracey Bawden for the way they had developed the calf.
Mr Mayo said the junior champion was well balanced.
"No matter where you look at her, from any angle she has no holes in her," he said.
Tracey Bawden said the junior champion had been third in its class at last year's event.
She and husband Cameron milk 200 cows on their own at Labertouche, Vic.
Their herd comprises Holsteins, Jerseys, Ayrshires and Brown Swiss.
"The Brown Swiss are mainly mine because I like them more," Mrs Bawden said.
"They're just so easy going and big loving animals."
The Bawdens plan to breed the heifer as soon as possible and hopefully bring it back to IDW next year.
