  1. Where next for Terminal Sire Recording? Samuel Boon, Signet Manager and EBLEX Breeding Specialist

  2. Performance recording has been a great success...... High rates of genetic gain for growth and carcase traits

  3. Success • Breeders are using EBVs to add value to ram sales • Increase in demand for recorded rams • Commercial understanding is increasing (but still a long way to go) Number of flocks recording is limited and hence industry impact could be higher

  4. Challenges Breeding Values are getting bigger...... Is it time to rebase?

  5. Challenges Breeders are looking for more regular BLUP information – 3 runs a year is limiting More crossbred animals and crossbred flocks are looking for useful EBVs Current BLUP solutions are limited

  6. Commercial demand....... At every sheep meeting I have spoken at for 15+ years someone has said “can we compare breeds” Would an indirect “comparison” – if promoted sensibly - assist breeders (and breeds) of high genetic merit sheep? Should Signet be helping the industry to find the sheep with the best genes – regardless of breed?.....

  7. We have been here before.....

  8. Current approach Index / EBV 1990 2013

  9. Current approach Index / EBV Charollais Suffolk Texel Meatlinc 1990 2013

  10. Across breed approach Index / EBV Charollais Suffolk Texel Meatlinc 1990 2013

  11. Combined breed evaluationsWhat are other people doing? Sheep Ireland (future?) SIL Central Progeny Test UK Dairy Evaluations “Everyone in one pot”, but breeds reported separately Lambplan Combined runs for Merino + Rest ICBF Beef in Ireland £ £ Starting with a simple approach – doesn’t preclude more advanced solutions in the future

  12. Where will we get crossbred data? • Existing members with crosses? • New members with crosses? • Other sources? Test flocks?

  13. Advantages (potentially) • More regular EBV updates • More efficient use of money to produce EBVs • More accurate EBVs for crossbreds • Greater accuracy values for all • Clearer message for commercial producers • Even greater interest in top end genetics

  14. Independence • Within breed rankings remain • EBVs across breeds • but breed specific indexes are possible • Breed specific genetic group solutions • For those not interested in other breeds • not really an issue • business as usual

  15. Crossbreds - are they inevitable? The introduction of Composites has not only lifted sheep performance by their own merit, it has also put a sharper focus on breeding and performance of purebred sheep Mark Young, Heartland Sheep October 2013 Threat? Opportunity?

  16. Summary This is a major opportunity to improve the way we identify and promote terminal sires with superior genes

  17. Thank you
