Southdown Meeting Lucy Webb Wilson and Samuel Boon
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 websitewww.signetsouthdowns.com
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

Genetic Trends Positive progress since 2008 in all traits across the Southdown breed.
Index since 2008
Growth EBVs Since 2008 Increase of almost 1kg in Scan Weight EBV in 5 years
Carcase EBVs Since 2008 Increase of approximately 0.3mm of muscle depth EBV across the loin
“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
Comparing performance BLUP Flock 1 Within Across Flock 2 Flock 3 = a contemporary group = genetic links between related animals

Where do unknown rams come in?
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.....
How do rams get the indexes they do?
Range of factors Own performance (if known) Relatives performance (if known) Progeny performance (if known)
Benoit – : Index:368 8week weight EBV kg Scan weight EBV kg 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: : : : : : 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.
Benoit – : SIRE Number of lambs scanned Average Age of Lambs at scanning Average Muscle Depth (mm) Average Fat Depth (mm) 165: : : : : : Muscle Depth EBV mm Fat Depth EBV mm 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
WEBBELLIS Flock EAST DEAN DEAN – 165: Index:238 8week weight EBV kg Scan weight EBV kg 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: : : : : : : 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
WEBBELLIS Flock EAST DEAN DEAN – 165: Muscle Depth EBV mm Fat Depth EBV mm SIRE Number of lambs scanned Average Age of Lambs at scanning Average Muscle Depth (mm) Average Fat Depth (mm) 165: : : : : : : 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
