The Mibus family's Glenara Merino stud was excited to accept the grand champion Merino ram of the show at this year's Sheepvention.
The win was the first supreme champion ram ribbon won by the stud operated by Trevor, Kathy, Rachael and Jacob at Dunkeld.
The ram had earlier been judged champion ram in the ultrafine section of this year's show.
Stud principal Trevor Mibus said it was the best result in 30 years of showing.
The ram was the result of an artificial insemination program from the Rockbank stud at Victoria Valley.
Mr Mibus said Rockbank had been a successful super fine, ultrafine stud over many years and they had utilised the genetics for more than 25 years.
"This winning ram is one of the best and biggest rams we have ever bred," he said.
"Our clip is very fine at 16.2 micron average and usually when we get into a big line-up like this we are a bit smaller than everyone else, but this ram is such a large framed ram ram with a large amount of wool and quality of wool.
"I wasn't confident going in because ultrafine don't normally win these things, it normally goes to the bigger sheep.
The ram won superfine in Ballarat and then progressed to the Australian Sheep and Wool Show in Bendigo.
The ram would now go to have semen collected to fill sales orders already taken before this result.
