  1. Rob Hodgkins “Genomics – how is WairereUK using this technology?”

  2. Genomic selection – how are we able to use it? • New Zealand currently offer the worlds only commercially available genomics test for sheep • 22 key performance metrics for animals with high % of New Zealand Romney • At least 2/3rds of animals DNA must be derived from New Zealand stock, and animal performance recorded on the NZ SIL System • Our animals full fill these requirements, and to my knowledge is one of the onlyflocks in the northern hemisphere able to use this technology

  3. Practical example one – accelerate genetic gain by using young stock All have gBV’s meaning we have the confidence to mate them with a small number of ewes (only 30-35) Early identification and verification of genetics, high index ram lambs (born April 2013) can be used with increased confidence. UK0263523 09477 UK0263523 09537 UK0263523 10123 UK0263523 10195 In addition all will be tested on the low density 5K chip in the next couple of weeks to give increased confidence around the joining.

  4. Practical example two – increased confidence using unproven stock UK0263523 08147 – Born April 2012 Believed to be the first animal in the northern hemisphere ever given a mBV on the sheep 50K system. High level of confidence in using across large number of animals 2013 joining Mated to 90 mixed aged, mixed ability ewes for one cycle Then mated to a further 70 ewe lambs on there first cycle

  5. Practical example three– A “yardstick” to compare our flock against the best in NZ DNA testing is very expensive so only the very best animals in New Zealand are analysed. Therefore that figure represents the top 2% of those that are tested. “i.e. the best of the best”

  6. Practical example four– access to difficult to measure traits MEAT YIELD Fat Lean Yield (FATY) Shoulder Lean Yield (SHLY) Loin Lean Yield (LNLY) Hind Quarter Lean Yield (HQLY) Lean Yield Weight Adjusted (LEANY) Health Facial Eczema (FE) (Not a problem in the UK at present) Faecal Egg Count 1 (FEC1) Faecal Egg Count 2 (FEC2) Adult Faecal Egg Count (AFEC) Lamb Dag Score (LDAG) Adult Dag Score (ADAG) PRODUCTION Carcase Weight (CWT) Live weight at 8 months (LW8) Live weight at 12 months (LW12) Ultrasonic Eye Muscle Area (EMAC) Adult Eye Live Weight (EWT) Weaning Weight (WWT) Eye Muscle Area (EMA) Number of Lambs Born (NLB) WOOL - Lamb Fleece Weight (LFW) Fleece Weight 12 Months (FW12) (Not a priority in the UK at present) Ewe Fleece Weight (EFW)
