1 Southdown Meeting Lucy Webb Wilson and Samuel Boon

2 Agenda 2013 performance and breed progression Getting connected… data entry by breeders, Pediweb Performance: connectivity and accuracy How and why do non-UK genetics perform they way they do? Getting the balance right: growth rate, muscle and fat Marketing and promoting the Southdown as a Terminal Sire The www.signetsouthdowns.com websitewww.signetsouthdowns.com

3 Signet bits....... Southdown achievements to date Current connectedness / linkage Testing the unknowns / why do rams get the EBVs they do? Getting the balance right – index weightings

4 Achievements – Genetic Trends

7 Genetic Trends Positive progress since 2008 in all traits across the Southdown breed.

8 Index since 2008

9 Growth EBVs Since 2008 Increase of almost 1kg in Scan Weight EBV in 5 years

10 Carcase EBVs Since 2008 Increase of approximately 0.3mm of muscle depth EBV across the loin

11 Connectedness

12 “An outstanding sheep is more likely to be found amongst 5,000 ewes than in a flock of 60.” Within-flock analysis Whole breed analysis

13 Comparing performance BLUP Flock 1 Within Across Flock 2 Flock 3 = a contemporary group = genetic links between related animals

16 Where do unknown rams come in?

17 Unknown Animals Unknown animals are just that “unknown” Assuming no parents recorded or other relatives known – they get the same EBVs as all other “unknown” males or females on the database – but with accuracy value of “0”......But they can move fast.....

19 How do rams get the indexes they do?

20 Range of factors Own performance (if known) Relatives performance (if known) Progeny performance (if known)

21 Benoit – 215680:090019 Index:368 8week weight EBV----2.14kg Scan weight EBV----3.84kg Looking at the raw data within the ram’s contemporary group for 2013 SIRE Number of lambs weighed Average 8 week weight (kg) Number of lambs scanned Average Age of Lambs at scanning Average Scan Weight (kg) 165:111462320.862317847.80 215680:0900193222.712816147.46 218:091661417.75318749.50 218:117012417.831813738.19 586878:09002118.50 83:091731819.27159828.80 Lambs were on average approximately 3-4kg heavier at 8 weeks Lambs achieved similar weights to two other sires despite being 17 and 26 days younger respectively.

22 Benoit – 215680:090019 SIRE Number of lambs scanned Average Age of Lambs at scanning Average Muscle Depth (mm) Average Fat Depth (mm) 165:111462317829.005.31 215680:0900192816129.204.95 218:091661318728.646.76 218:117011813725.614.12 586878:09002 83:09173159822.212.62 Muscle Depth EBV----2.37mm Fat Depth EBV-----1.12mm Looking at the raw data within the ram’s contemporary group for 2013 Lambs achieved similar muscle depths at scanning to two other sires despite being 17 and 26 days younger respectively. Despite achieving high levels of muscling across the loin the lambs were leaner than those by other sires

23 WEBBELLIS Flock EAST DEAN DEAN – 165:092132 Index:238 8week weight EBV----0.92kg Scan weight EBV----2.91kg SIRE Number of lambs weighed Average 8 week weight (kg) Number of lambs scanned Average Age of Lambs at scanning Average Scan Weight (kg) 165:066321216.531013035.48 165:0921321116.051114140.11 64:10046520.78110530.40 640:1200315714.27714331.83 738:06010415.40313528.60 968:1100030816.64814337.13 968:1200070220.10114247.00 Lambs achieved slightly above average growth to 8 weeks when compared to their contemporaries Lambs grew strongly to scanning gaining 3kg more than those that had a similar weight at 8weeks by a different sire

24 WEBBELLIS Flock EAST DEAN DEAN – 165:092132 Muscle Depth EBV----2.38mm Fat Depth EBV----0.28mm SIRE Number of lambs scanned Average Age of Lambs at scanning Average Muscle Depth (mm) Average Fat Depth (mm) 165:066321013025.025.02 165:0921321114127.835.28 64:10046110522.934.57 640:1200315714322.824.99 738:06010313523.964.04 968:1100030814325.834.84 968:1200070114228.988.60 Lambs achieved above average muscle depths when compared to others of similar age by different sires The lambs we slightly fatter than their contemporaries leading to the positive fat EBV
