Dohnes unveil new judging system at ASWS

July 18, 2016 – by Kim Woods Outcross Media

 

Dohne sheep returned to the show ring after a 40-year global absence to unveil a unique judging system combining objective data and subjective assessment at the Australian Sheep and Wool Show.
Held on July 16-17 at Bendigo, the judging drew 60 rams from four states and featured a weighted index for carcass and wool traits, combined with visual assessment.
The objective system, which comprised 65 per cent of the total score for each entry, was devised by sheep industry consultant Geoff Duddy, Leeton, NSW.
Mr Duddy said the system used Australian Sheep Breeding Values focused on a 70 per cent weighing on post weaning weight, post weaning eye muscle depth and post weaning fat, and 30 per cent on yearling clean fleece weight.
“Thirty five per cent of the total score was from the visual assessment and conformation to make sure the rams on display were suitable for the Dohne breed,’’ he said.
“It worked well – the 70:30 weighting is where the Dohne is sitting with respect to their income from meat versus wool.’’
Mr Duddy said the judging model could be applied to other sheep breeds.
“In the future, with Merinos in particular, we may see judging not just be on a visual critieria or raw data – on the maternal side it has huge potential to incorporate objective measurement,’’ he said.
Australian Dohne Breeders Association president Richard Beggs said the combination of subjective and objective components in the show ring had not been done before.
Mr Beggs said the judging criteria would be reviewed but had been a positive exercise for the breed.
He said the Dohne’s subjective and objective classifications set it apart from other dual-purpose sheep breeds.
“All the breeds have some sort of a performance class where they are judged with some objectivity as well as subjectivity, and there are still a lot of classes purely subjective,’’ Mr Duddy said.
“In the Merino breed, the all purpose classes attract about 150 entries – they could look at our system and move towards incorporating ASBVs rather than raw data in the future.
“It takes out the environmental differences and puts sheep on a level playing field, providing they have good enough linkages.’’

Judging was undertaken by dual-purpose sheep breeders Andrew Bouffler, Lockhart, and Barry Lang, Oberon, NSW.
The supreme exhibit, Macquarie 141051, emerged from a strong class of 29 senior ram entries to be sashed as senior, grand and supreme champion.
Sired by MD 103467 and out of MD 126015, the June 2014 drop, March shorn ram had a Dohne index value of 174.2, post weaning weight ASBV of 6.1kg, post weaning eye muscle depth of 1.4mm, post weaning fat 0.2mm, yearling clean fleece weight of 16.8 per cent, and yearling fibre diameter of -0.2.
Macquarie stud principal John Nadin, Warren, NSW, said the twin ram was out of the stud’s most productive Majestic family.
“This is the first time Dohnes have been shown in Australia and because of the heavy emphasis on objective measurement, (showing) has always been a sticking point among breeders,’’ he said.
“The committee which got this up and running had to keep in mind the feelings of the membership so stuck to the Dohne philosophy of 70 per cent meat and 30 per cent wool.
“Time will tell whether we got it right but it’s unique – it will be for the membership to decide whether it is worth going ahead in the future or not.
“I have been coming to Bendigo for 12 years and this is the biggest crowd I’ve ever seen in the Dohne marquee.’’
The Cameron family, Koonik Dohnes, Nurcoung, Vic, exhibited the junior champion ram and ewe, and senior pair of rams.
The reserve grand champion ram was exhibited by Murray Rogerson, Stirling Dohnes, Glenthompson, Vic.
In the pairs, Don and Karen Mills, Kardinia Dohnes, Corowa, NSW, exhibited the junior pair of rams and supreme pair.
The show marked the 50-year anniversary of the Dohne breed and was a stop over for international delegates visiting Australia as part of the Global Dohne Conference and tours from July 15-29.
The junior champion ram was sponsored by Macquarie Artificial Breeders and Riverina Genetics, and the Supreme Dohne by Elders.
