JIVET & DNA supercharge sheep breeding at Leahcim

Published on 27 Nov 2013

Andrew Michael has taken sheep breeding beyond the cutting edge and into new territory, with a new program that is super-charging the speed of genetic gain in his flock.

Known as JIVET -- juvenile in vitro embryo transfer -- the program has already delivered stud lambs years in advance of those from his conventionally joined flock, thanks to a combination of old-school visual appraisal and traditional measurement techniques, with the latest in DNA testing and embryo collection methods.

Team DNA profiling delivers highly predictable performance of future lambs

Published on 11 Dec 2013

DNA testing not only identifies the breeding potential of individual rams, the benefits to sheep breeders multiply dramatically when a preferred genetic profile is selected for a team of rams, according to Riverina studmaster Murray Long.

Genomic testing maps out path for leading breeders

Published on 4 Mar 2014

Genomic testing has dramatically changed ram selection on Dale Price's Glencoe farm, identifying superior stock for improving his flock, as well as exposing traits in rams that he would otherwise have selected that would have set back the rate of genetic gain. Mr Price runs Majardah Poll Dorsets, part of the Meat Elite Group of studs which participated in the commercial - style DNA trials conducted as part of the Genomics Pilot Project by the Cooperative Research Centre for Sheep Industry Innovation (Sheep CRC). This year the group DNA tested 188 rams out of a total of 2500 put up for possible selection and ended up with a team of 14 young rams that were star performers in specific traits, while at the same time maintaining genetic diversity. The DNA tests provided data on a broad range of traits, however Mr Price said the group was particularly focussed on improving meat eating quality.

DNA testing turns meat quality dream into reality

Published on 7 Apr 2014

The long-held dream of guaranteeing the eating quality of every single sheep that comes off his farm is now a reality for Western Australian sheep breeder Dawson Bradford.

Mr Bradford believes genetic testing will help to eventually eliminate variability in meat quality, however its success means doing the hard work now to identify the right breeding stock for the industry.

He is already using DNA testing to identify rams in his flock that possess genes for desirable but hard-to-measure traits such as intra-muscular fat, tenderness and lean meat yield.

Early adoption drives accelerated progress at Centre Plus

Published on 11 Feb 2015

A willingness to try something new and to adopt technology early has dramatically changed for the better in the Mortimer family’s sheep breeding operation in Central West NSW.

The Mortimers and the members of the Centre Plus ram breeding group are enjoying the benefits of accelerated rates of genetic improvement in their flocks with generation intervals being shortened by up to a year.

Objective data for ram teams the key to success at Trundle

Published on 23 Mar 2015

Close analysis of objective data and a commitment to buying rams in well-matched teams is driving significant and consistent improvement across the flock of Central West NSW producer Anthony Drenkhahn. Mr Drenkhahn has enjoyed average lambing rates of 112 per cent and up to 126 per cent from his 2000-ewe Merino flock, which he puts down to the selection accuracy provided by Australian Sheep Breeding Values (ASBVs).

And he can see more rapid gains and  major labour savings on the way as a result of using DNA testing.

Flock transformed in just six years

Published on 20 Jun 2015

Transforming the genetic make-up of a flock of sheep is no longer an inter-generational task, but one that has been achieved by Queensland woolgrower Stuart Mitchell in just six years through the use of objective selection tools.

Mr Mitchell and wife Barb run 9000 Merinos at ‘Cashelvale’, Bollon, and have dramatically transformed the flock’s appearance and performance so they could cease mulesing without putting the flock at risk of flystrike, while also achieving finer micron wool.

Mr Mitchell said the keys to success were having a clear breeding objective, selecting rams against those objectives using Australian Sheep Breeding Values (ASBVs), and buying teams of similar rams for across the board genetic impact.

DNA Flock Profile proves accurate at Peter Westblade trial

Published on 30 Jan 2017

The Peter Westblade Merino Memorial Challenge (PWMMC) has proved the accuracy of the new DNA Flock Profiler Test under development by the Cooperative Research Centre for Sheep CRC.

During its initial testing phase in early 2016 the Sheep CRC investigated if average genomic breeding values could be calculated for a sheep flock, even with distant or unknown relationships to the reference population.

Building apps for the grazing livestock industry

Wednesday 22 February 2017, 3:00pm
Biological Sciences Lecture Theatre (S003)

A symposium on the development of web-based apps designed to provide information about complex grazing systems was held on 22 February 2017.  Drawing on a broad range of expertise in livestock production, soils, pastures, data science, simulation and machine learning models the apps form a natural collection point to connect science with practice.

These are the presentations from that symposium:
