Understanding Genomics

Genomics is the knowledge of genes and chromosomes and how they affect characteristics of an individual. Genomics is already allowing our sheep researchers to predict the later performance of sheep from an early age — even just after birth.

In sheep, genomics is mainly used to study the relationship between performance of important traits and known points on the sheep’s chromosomes, known as SNPs (pronounced ‘snips’).

The measured performance of a trait in many individual sheep is compared with a large number of SNPs in those same individuals. The pattern that emerges shows which SNPs are related to the trait and how strong an effect the presence of each SNP has on the characteristic.

Once sufficient tests are completed, these form the basis of a DNA test that can be used commercially to predict trait performance in other individual sheep. The DNA test results will be reported through Sheep Genetics in the form of enhanced Australian Sheep Breeding Values (ASBVs). Genomically enhanced breeding values offer new opportunities for early selection decisions with young sires to achieve genetic improvement across a range of traits including new traits that breeders are unable to measure on-farm, such as intramuscular fat and shear force or tenderness, or take a long time to measure, such as adult fleece weight and fibre diameter.

The Sheep CRC and Sheep Genetics have already completed an initial round of comparisons (Genomics Pilot Project I) to create research breeding values (RBVs) based on genomic data for some 360 young industry sires from 200 breeders for a number of important performance traits.

A second pilot (Genomics Pilot Project II) involving 1,000 young sires is underway to further develop commercial SNP tests and the inclusion of their results into Australian Sheep Breeding Values (ASBVs).

Commercially available SNP tests from this work are likely to be available for sheep during 2012.

Tech-savvy students drive Farrer High to the top of RamSelect
Listing their catalogue via the RamSelect Plus app has showcased the value of early adoption of new breeding technologies and opened new markets for the students at Farrer Memorial Agricultural High School. Based in Tamworth NSW, the school’s agriculture subject offering includes a Year 9 and 10 ‘animal management course’, in which students take on the tasks associated with running the Farrer White Suffolk stud.

DNA Flock Profiler responds to producers needs
Breaking down a perception-driven market with objective genetic data was the impetus for sheep breeders Andrew and Barbara Read to conceive an idea which has now been realised in the form of the Sheep CRC’s DNA Flock Profile test. The Reads, from "Oak Hills", Nangus, NSW, first approached Sheep CRC chief executive James Rowe two years ago at a producer field day with the idea of developing a DNA test to profile the genetic...

Sheep researchers star on international stage
The next generation of red meat researchers are being inspired by the success of the sheep industry’s stable of young scientists who are starring on the world stage. Five Murdoch University scientists were recently chosen to deliver oral presentations, all linked to research they are conducting through the Cooperative Research Centre for Sheep Industry Innovation (Sheep CRC), at the recent International Symposium on Energy...

Breeding for flystrike resistance to be made easier
Genetic research into the heritability of flystrike susceptibility in sheep, and its expression in different operating environments, is set to be incorporated into new tools to assist breeders make more informed selection and flock management decisions. Tracie Bird-Gardiner, from the NSW Department of Primary Industries, has spent the last four years collecting and analysing data from fly-struck sheep in the industry’s...

Commercial Merino producers - opportunity for DNA pilot project
Commercial Merino producers have the opportunity to be at the cutting edge of DNA research by participating in a pilot trial of the new Flock Profiling Test from the Cooperative Research Centre for Sheep Industry Innovation (Sheep CRC). The Sheep CRC will provide support for up to 100 Merino producers to define the genetic merit of their flocks. The profiling test involves randomly sampling 20 young ewes for DNA testing.

Understanding why farmers are pressing the app buttons
Despite the proliferation of new technology in agriculture, very little is known about the effectiveness of these new tools in improving primary productivity and adoption of new practices. A new research project from the Cooperative Research Centre for Sheep Industry Innovation (Sheep CRC) will evaluate the use of smartphone apps in the industry and producer attitudes towards these tools, in order to ensure future tools and...

Ram team records unlock the secrets to better breeding
Keeping accurate records of his ram teams has allowed South Gippsland second-cross lamb producer Paul O’Sullivan to benchmark his business against industry averages and to refine his genetic selections to take flock productivity to the next level. Mr O’Sullivan was impressed by the benchmarking capabilities of the new RamSelect Plus app when it was launched at LambEx by the Cooperative Research Centre for Sheep Industry...

Sheep breeders rush to RamSelect Plus
Sheep breeders are embracing RamSelect Plus in droves, with close to 4000 rams from 60 different studs listed on the site since the start of July. And there are already over twice the number of registered users than there were at the end of the 2015 ram-selling season. Sheep CRC chief executive James Rowe said the early-season figures were a strong endorsement of the need for easy-to-use applications that provide personalised...
