Signet Update
Presentation 1. Signet overview 2. Combined Breed Analysis 3. RamCompare 4. Raucous applause
Signet Role Provide genetic evaluations to sheep and beef producers to identify animals with superior breeding potential. Enables the industry to capitalise on genetic improvement
Signet Activities 1. Performance Recording Services Sheep Cattle (those that need us) 2. Knowledge transfer relating to Breeding and Genetics 3 Research and development RamCompare & Beef Feed Efficiency

Where next for Terminal Sire Recording? Combined Breed Analysis
Performance recording has been a great success... High rates of genetic gain for growth and carcase traits
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
Challenges Breeding Values are getting bigger... Is it time to rebase?
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
Index / EBV Current approach 1990 2013
Index / EBV Current approach Charollais Suffolk Texel Meatlinc 1990 2013
Index / EBV Across breed approach Charollais Suffolk Texel Meatlinc 1990 2013
Combined breed evaluations What are other people doing? UK Dairy Evaluations Everyone in one pot, but breeds reported separately Lambplan Combined runs for Merino + Rest Sheep Ireland (future?) SIL Central Progeny Test ICBF Beef in Ireland Starting with a simple approach doesn t preclude more advanced solutions in the future
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
Independence Within breed rankings remain EBVs across breeds Need to look at breed specific indexes Breed specific genetic group solutions For those not interested in other breeds not really an issue business as usual
Summary Results from research on Combined Breed Analysis to be released at November 2015 SBRT With a view to introducing service in 2016
Experimental design RamCompare is aiming to establish a commercial progeny test for terminal sire breeds Data will enable a comparison of the commercial performance of progeny by genetically different rams
RamCompare Project runs for two breeding seasons Starts May 2015 Commercial progeny testing Six flocks across GB Using AI and single sire mating Testing 67 rams over two years Texel, Suffolk, Charollais, Meatlinc and Hampshire Down Balanced across top 20% for carcase traits Aims Use commercially collected data in genetic evaluations Could help validate Combined Breed Analysis

Trial design 120 ewes to AI for four rams 30 ewes per sire 200 ewes to natural service for five rams 40 ewes per sire Farms will use Suffolk, Texel and Charollais and either Meatlinc or Hampshire Down High degree of replication between farms / years
Predicted number of lambs per ram 30 ewes to AI Conception rate 60% Rear 1.4 lambs/ewes 25 lambs per sire 40 ewes to natural service Conception rate 90% Rear 1.4 lambs/ewes 50 lambs per sire
