  1. Introduction Sheep genomic technologies and the Information Nucleus James Rowe

  2. New ways to estimate breeding values

  3. End user involved in design specification Select 100 rams/year For 5 years Sheep Genetics (End User) and Sheep CRC Design Team Stud Ram Breeders Measurement Protocols 8 farms in 4 States 5 Organisations 4,500 ewes/year 5 years 18,000 lambs Lambing records + growth On farm fat/muscle scan and blood/ DNA samples Reproduction of female progeny AI Program Shearing 18 Organisation 5 Abattoirs 9 laboratories 75 researchers >150 traits measured > 5 Million data entries >10,000 DNA profiles Meat Processors DNA Extraction Base data joining records Parasitology Behaviour Fleece data Wool Laboratory Consumer testing Meat Science Laboratories Reproduction data Carcase data Genotyping DNA analysis Wool data Meat analysis Meat quality Sheep CRC Information Nucleus Data Base Sheep CRC Research Teams Genetics/Genomic, Meat, Wool, Reproductionand Parasitology Genomics DNA predictions of breeding value Improved accuracy of genetic parameters New traits • Research Papers • Technical Reports • Training programs End user delivery for 70% of Terminal rams for 35% of Merino rams Sheep Genetics data base and operational software LAMBPLAN MERINOSELECT Delivery of genetic information to stud ram breeders and producers to select and use better rams Impact through increased productivity gain, improved product quality and easier management

  4. Genomic BVs most valuable - difficult to measure traits- traits measured late in life • Productivity • Lean meat yield • Dressing % • Consumer eating quality • Intramuscular fat • Consumer health • Omega-3 and Iron

  5. Genomic Pilot Projects 2012 • Parentage and horn/poll • 10,000 tests at $16 • 100 samples per breeder • Genotyping50k SNP test $50/test • 2,000 tests with half for ‘whole drop’ testing

  6. CRC Extension application • Next generation genotyping • New traits – welfare, quality • Very fast and effective adoption • New breeding designs • Active supply chain engagement New money and good leverage
