Why are we here?• Follow up from spring plenary meeting
• Suggestion of BCEF to review current TB controls and calf health implications
• Strategy Team – meeting inter-plenary:– Current TB control– Future changes – AQUs from January 2013– Producer feedback to proposed changes?

Background• Westpoint practice report May plenary• Variation TB controls differed across UK• 65 dairy units from 211 dairy farms at that time
were/had been under restriction• >1,000 B&W bull calves shot in last year• Only in SW were AQUs and AFUs really
working to manage TB restricted calves• Problem growing across UK?

Approved Quarantine Units

AQUs in England• 135 registered premises in England
• Handling around 20,000 calves per year
• From small to large scale units
• Blade Farming:– 6 x AQUs in operation– Handling ~3,000 calves/year– 15% of all calves through 5% of units– Supplying calves to finishing across SW

AQUs in England (2)• Moratorium on AQUs for 18 months• EU concerns over biosecurity and control for TB
spread:– DEFRA – AHVLA review– Deficiencies in several AQUs visited– Pressure on UK to remove this “loophole”
• Change in legislation from January 2013:– All AQUs final intake– Cease operations from last batch out

Current system has to change for EU TB control

DEFRA changes TBIN 05-12• TB information note on DEFRA website
• http://www.defra.gov.uk/animal-diseases/files/tb-infonote-1205-changes-to-movements.pdf
• Removal of AQUs
• Implementation of new “Feeder AFUs”
• Restocking and other testing guidance
• Changes in AFU testing requirements
![Page 9: Update on the TB control program and calf health Rob Drysdale MRCVS Westpoint Veterinary Group Ltd](https://reader036.vdocuments.site/reader036/viewer/2022062518/56649c935503460f9494e607/html5/thumbnails/9.jpg)
Assured Finishing Units• Currently 109 AFUs licensed in England• All based in SW and Midlands
– SW region = 73 units– Midlands = 36 units
• Cattle from multiple TB restricted farms• Finishing to move straight to slaughter• AHVLA undertake inspections• Regular TB testing
![Page 10: Update on the TB control program and calf health Rob Drysdale MRCVS Westpoint Veterinary Group Ltd](https://reader036.vdocuments.site/reader036/viewer/2022062518/56649c935503460f9494e607/html5/thumbnails/10.jpg)
Update from January 2013• No AQUs – to be phased out• New “feeder AFU” category• AFU category – change towards a more
open system• Split AFUs proposed:
– Risk based management– With grazing licence (TB tested still)– Without grazing (no/minimal TB testing)
![Page 11: Update on the TB control program and calf health Rob Drysdale MRCVS Westpoint Veterinary Group Ltd](https://reader036.vdocuments.site/reader036/viewer/2022062518/56649c935503460f9494e607/html5/thumbnails/11.jpg)
New AFUs• Currently 60 AFUs licensed with grazing
– SW region = 43 units– Midlands = 17 units
• High risk of spread and potential for wildlife exposure?
• Short term continue testing grazing AFUs
• Long term remove licenses/phase out?
• Only 40% of AFUs have no grazing
![Page 12: Update on the TB control program and calf health Rob Drysdale MRCVS Westpoint Veterinary Group Ltd](https://reader036.vdocuments.site/reader036/viewer/2022062518/56649c935503460f9494e607/html5/thumbnails/12.jpg)
• Take calves from multiple TB restricted holdings
• Rear calves through to then move on under licence to finishing AFU
• Risk based management• AHVLA inspection• Designed solely for
calves to certain point
Feeder AFUs
![Page 13: Update on the TB control program and calf health Rob Drysdale MRCVS Westpoint Veterinary Group Ltd](https://reader036.vdocuments.site/reader036/viewer/2022062518/56649c935503460f9494e607/html5/thumbnails/13.jpg)
What is really needed?• Consider number TB restricted holdings?
• Latest DEFRA stats to August ‘12– England currently at >5,500 herds under TB2
• Take a single region:– SW was >3,400 herds under TB2 (1,600 new)– SW >3,500,000 head of cattle tested– SW OTF herd 18,400– Demand for AFU system is very high

What is really needed? (2)• Old AQU/AFU system handled:
– ~20,000 calves/year– >100,000 head all TB animals/year
• Require at least 50% of old AQUs to move to feeder AFUs to stand still?
• Demand for beef high now but...– Feed costs high but price rising?– Beef “throughput” down year on year 8%
![Page 15: Update on the TB control program and calf health Rob Drysdale MRCVS Westpoint Veterinary Group Ltd](https://reader036.vdocuments.site/reader036/viewer/2022062518/56649c935503460f9494e607/html5/thumbnails/15.jpg)
Can the new system work?• Feedback from Blade AQUs is promising• AFU system may be more flexible in TB endemic
areas:– Take calves earlier into AFU system– Create market for currently low value animals– Many more units required
• Best practice needed – still potential disease risk eg colostrum management, Cryptosporidiosis, Coccidiosis etc.

• Need to consider special requirements for young calves = planning with vet?
• Multi source calves• Multiple disease risks• Management:
– Size for age– Exposure and temperature– Feeding and time
CONSIDER COSTS
As a vet what is needed?

Is there a real market for TB produced beef?
