Are there any regional differences in TB
controls for calves?Rob Drysdale MRCVS
Westpoint Veterinary Group Ltd
Who is Rob Drysdale MRCVS?• Managing Director Westpoint Vet Group Ltd
• Farm vet for 17 years
• Particular interest in calf health and welfare
• Vet to Blade Farming SW Ltd:– Complete and integrated beef supply chain– Produced more nearly 20,000 calves last year– UK’s largest integrated beef producer
Westpoint Vet Group• 16 practices across UK with 50 farm vets
• Total practice over 3,000 clients
• 250+ dairy farms:– More than 90,000 dairy cows (av herd 350 cows)– Low input extensive to high input intensive
• Over 300,000 head of beef and youngstock:– Fattening units from 100 to 8,000 head/year– Suckler farms from 20 to 1,000 cows
Background• Calf Forum Strategy Group project
• Investigate the impact of TB on dairy units in different regions of the UK
• Meeting with WVG Senior Vets twice yearly had raised issues of how the varying regions interpret TB annexes
• Blade Farming experiences – rearing units and supplying dairy farmers
Approved Quarantine Units?
AQU system – works for Blade
Blade Farming and AQUs• Frustration for calf supply chain
• Richard Phelps could see potential
• Started in 2005 with 1 x TB approved unit
• Now have several sheds on several farms each with own TB licence as AQU
• Capacity of around 2,000 calves per cycle
• Around 1.5 cycles per AQU per year
Blade Farming and AQUs• System works with local AHVLA support
• Retailer and processor support
• Breeds – many but B&W difficult to justify
• Great value weaned “store” cattle
• Move to finishers on contract for slaughter
• Dedicated farmers and also occasional purchasers
AQU system can work
Background• WVG practices split into 5 English regions
• Director or Senior Vet heads up each area
• Regions have different DEFRA offices managing them
• Vets and farmers frustrated through different approaches by DEFRA Vets
• AHVLA – new team from 2011
Background• Five distinct regions – AHVLA offices:
• North West = Carlisle
• Midlands = Stafford
• East Anglia = Chelmsford now Reading
• South West = Truro and Exeter
• South East = Reading
• 10 units SW Scotland with 10,000 cows
• Blade Farming – TB controls
North West• 41 dairy farms with 15,000 cows
• 4 holdings under TB restriction last 2 years
• No units currently under restriction
• No local TB controlled rearing available
• All bull calves shot
• Approx 400 calves shot in period
Midlands• 27 dairy farms with 5,700 cows• 11 holdings TB restricted last 2 years• 5 units currently under restriction• Little support for TB controlled rearing in
region and DEFRA “seems unwilling” to support
• Not all bull calves shot• Approx 500 calves shot in period
East Anglia• 28 dairy farms with 6,900 cows
• No holdings TB restricted last 2 years
• Beef units affected with 3 under restriction
• Good support for TB controlled rearing in region with one specialist finishing unit in place
• No bull calves shot!
South East• 65 dairy farms with >34,000 cows
• 18 holdings TB restricted last 2 years
• 4 units currently under restriction
• Varying support for TB controlled rearing in region. No specialist rearing or finishing units in place
• Over 500 bull calves shot!
South West• 50 dairy farms with >18,000 cows
• Only 12 holdings not been affected by TB restrictions in last 2 years
• 20+ units currently under restriction (dairy)
• Good support locally TB controlled rearing in region. Several specialist rearing and finishing units in place
WVG and TB in South West• Working with 8 AQU sheds
• Handling total of 1,000 calves each cycle
• Average of 1.7 cycles per year
• Total beef x and dairy bull calves on the current restricted farms = 3,000+
• 3 x actual TB breakdowns in last 4 years
• Estimate over 1,000 B&W calves shot!
Conclusions (1)• All collated from WVG vets and practices?• Frustration felt by farmers and vets:
– Veterinary variation – advice AHVLA– Regional variation – implementation of TB
control measures– Wastage when system is meant to be in place
• Now the regulations have been updated again
Conclusions (2)• Drawbacks exist – the system is not perfect
even when working:– Spread of disease potential risk– TB test is not infallible (70% sensitive?)– Extreme biosecurity needs to be considered
• Testing procedures and systems could be better?
• No new AQUs being licensed in SW?
Over to you – any questions?
