Why Southdowns
• Docile and easy to handle• Tight stocking/ folded• Early finishing potential• Early relief of grazing pressure• Lambing ease• Outstanding conformation• Best tasting lamb• Past experience• Looks!

Grazing and grass
• Buy-in most hay• Permanent pasture (tenanted FOC)– 80 kgN/Ha
• Leys – 180kg N/Ha (subject to rain/soil moisture)
• Establishing new leys out of arable– Autumn undersown WW with PRG/clover
mix or – HSG grasses sown with
Rye/Westerwolds/IRG cover

Tups and tupping
• Ewes flushed on grass or with ewe nuts
• New for 2010– Ewes sponged to synchronise
lambing– PMSG to increase ovulation rate in
shearlings and some ewes– 7ewes per ram

Lambing
• Ewes in at Xmas• Lamb indoors Feb- Mar• Keep in until grass and weather
“fit”• Lambs dressed & weighed at
birth• Tails and castration at 4-6 days

Health
• Work with young vets on Flock Health Plan
• Open flock while growing – No quarantine– Feet and worm new arrivals
• Blue Tongue Vaccine• Heptavac P• Not currently– Scrapie testing… Autumn 2010– Maedi Visna

Worming and Flystrike
• Worming– No FEC– Land sheep free until 2008– Worming until 12 months
• Panacur -white (fenbendazole) and Cydectin – clear (moxidectin)
– alternate years
• Flystrike– Vetrazin (cyromazine)/Crovect (cypermethrin)
late March to shearing– Vetrazin post shearing– Crovect for misses

Signet Recording
• More scientific way to analyse performance and genetics
• “Marketing” edge for unshown flock
• Benefits commercial breeders who want high performance terminal sire

Signet: What’s involved
• Flock breeding data• Birth weight• Eight week weight• 140 day –Weight– Scan• Muscle• Fat
• £££s

Challenges
• Lowland flock – Flystrike– Twin lamb disease
• East Anglia– Climate and soil– Limited livestock
services• Markets/abattoirs• Veterinary resources• Fallen stock
