A rewarding decision for the Mitchell family of Culcairn who, not only came away with the most successful award, but defied odds taking out supreme White Suffolk exhibit with their grand champion ewe Rene 27/18 during her debut show judged by Chris Badcock of the Fairbank stud, Tasmania.

Kicking off her show career she was sired by the $8000 Tasmanian ram, Sunnybank 45, they purchased three years ago in Bendigo Elite White Suffolk Show and Sale.

Purchased for his structure and width of loin according to Rene co-principal Scott Mitchell, the Sunnybank 45 sire is stamping his progeny with quality.

"We bought 13 sheep here, and we won every class but one in the rams, getting either first or second in every class we entered in - and they are all by him, but one, so he is really doing a great job for us," Mr Mitchell said.

"We had previously won supreme in 2007, but haven't been back since 2008, so we had planned to come up here and have a real crack at the NSW show."

The supreme winning female will now go on to the Bendigo Sheep Show in July, before she treks over to South Australia for the Royal Adelaide Show in September, and back to Bendigo for the Bendigo Elite White Suffolk Show.

"Following that she will go into an ET (embryo transfer program). I already have the sire we will join her to picked out,

"Normally every two or three years we do an ET program, so we are due to do one and I have a reasonably handy team. I want to utilise those ewes as best we can.

"The judge commented today on the supreme ram and ewe, and which will contribute more to the breed, and normally they go for the ram but in this day and age you can do ET and you can get an increased amount of progeny on the ground, from the ewe side, so that is what we will be doing."

Pairing up with her siblings, the Rene 27/18 ewe was part of the Sunnybank 45 progeny group that proved their consistency by taking out the Keith McIntosh Memorial Shield for the White Suffolk sire's progeny group class.

The group also included the reserve champion ewe Rene 31/18 and the reserve champion ram Rene 64/18.

They also won the group of one ram and two ewes milk tooth only class, and the best White Suffolk head.

The supreme and grand champion winning ewe was up against the grand champion ram from the Barker family's Timor stud, Parkes.

This significant win struck a cord with many throughout the shed as the winning ram, known as Timor Martin's Legacy 31, was the result of a kind gesture from the late Martin Gilmore of Tattykeel, Black Springs.

Jason Barker from Timor stud said they were about to kick off an embryo program, when a week before something went wrong.

"I was in the process of moving semen from one artificial breeding service to another, and the AI tank went dry so I lost all my semen," Mr Barker said.

"I was talking to Martin Gilmore about it and he straight up made the offer to send semen up to us and made this all happen.

"So Marty saw the lambs before he died but it is kind of a bittersweet moment."

The August-18 drop embryo transfer ram was by $36,000 sire in Depta Grove Breaker and was one of about seven progeny that the Barkers have.

"He won champion White Suffolk at the Cowra lamb show last year, and he will be retained within the stud," he said.

Other highlights in the White Suffolk show include the ram objective measurement class being won by Rene 176 with a score of 71 points ahead of Macarthur Anglican School with Macarthur 25 in second on 70.085, and the ewe objective measurement class being won by Rocdell 197 with 76.7 points ahead of Rene 31 in second on 76.2.
