FOR the first year in history a Brahman bull has won the inter breed champion at the Ekka in Brisbane.

Viva Mario bred by Viva Brahman Stud in Middlemount won the best bull in the Brahman class and went on to beat all other breeds from across Queensland to take the winner's ribbon.

Viva Mario is affectionately known as the one-tonne bull because he weighs about a tonne.

He actually weighs 1,030kgs, is 32 months old and was the heaviest bull at the Ekka this year.

Terry Randell is the one responsible for the bull's show-winning form and said he was extremely proud to win the Champion of Champion's title.

"For it to come together like this is pretty special," he said.

"Most people were pretty chuffed. When he won it was the biggest roar and cheer I have ever heard."

Not one to rest on his laurels Mr Randell said the real test of Viva Mario would be when he now went off to meet 60 or so "girlfriends" in the paddock. "The true measure of a bull is to see how good the calves he produces are," he said.

Mr Randell said before the judging all the bulls underwent an ultrasound to examine their muscle area.

Viva Mario had the biggest eye-muscle area of any bull at the Ekka.

"When you are selling them it means you get bigger rib steak fillets," Mr Randell said. "We pay for weight and if he can go around and serve more cows than a bull that will break down, that is dollars in our pocket," he said.

The Ekka began last Friday and runs until August 14.
