LAMBPLAN
MERINOSELECT
End user delivery
for 70% of Terminal rams
for 35% of Merino rams
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
Sheep CRC Research Teams
Genetics/Genomic, Meat, Wool,
Reproduction and Parasitology
• Research Papers
• Technical Reports
• Training programs
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
Genomic Pilot Projects 2012
 Parentage
and horn/poll
–10,000 tests at $16
–100 samples per breeder
 Genotyping 50k SNP test $50/test
–2,000 tests with half for ‘whole
drop’ testing
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
