3 steps to implement a bovine TB contingency plan

Farmers should carry out a three-step contingency plan to ensure they are prepared for the stress and potential financial implications of a TB breakdown.

This is according to Sarah Tomlinson of Westpoint Vets and the TB Advisory Service, who recently advised clients that it’s best to ā€œhope for the best, but prepare for the worstā€.

ā€œA lot of farmers say there is huge stress and anxiety in waiting three days for the TB read day, so I’m telling clients to work out a plan beforehand,ā€ she told a Dairy-Tech webinar last week (5 February).

She advised how to undertake a bovine TB contingency plan should movement restrictions be imposed, and reactors isolated and slaughtered.

She said: ā€œThe mental health impacts of TB is often underestimated by the public, government and farmers themselves.

ā€œFeeling the loss of stock and genetics that have taken generations to build up – not just the financial impact – is massive. This isn’t just about the potential end of a business, but the loss of a way of life, a vocation, and family homes.ā€

1. Assess effects if herd TB breakdown was to occur

  • Heifer rearing away from home
  • Selling breeding stock, stores or calves younger than 42 days
  • Flying dairy herd – restrictions on buying in mean you can’t bring animals on to a TB-restricted holding until you have completed your first short-interval test – and even then the Animal and Plant Health Agency has to approve it
  • Consider your milk contract – are there any penalties for over/underproduction and is calf euthanasia allowed?
  • Effect on throughput and future cashflow of fatstock

2. Forecast business cashflow

  • What happens if you can’t sell stores as planned?
  • Can you afford bedding and feed to house and finish cattle?
  • How would a smaller herd (due to fewer incoming cows – if a flying herd) affect production and profit?
  • What effect would rearing all calves have on income and stocking density?
  • Could you sell into an approved finishing unit (AFU)?
  • Think long term – could a new shed being put up be badger-proofed and be suitable as an AFU/isolation unit? This needs to be planned, as it can only be applied for while the unit is TB-free

3. Evaluate short- and long-term actions

  • Sell calves and youngstock following a clear pre-movement test, especially if movement restrictions would be in place over winter, to ease feed and space pressures
  • Consider if becoming TB-accredited through the Cattle Health Certification Standards (Checs) TB scheme would be worthwhile
  • Research local AFUs by checking the ibtb.co.uk map (they are marked as purple squares on the map). Ask them about age of cattle taken, prices and capacity
  • Research other holding arrangements. These cannot be licensed once you have a breakdown, only before (see ā€œHolding options and rules for TB-hit herdsā€)
  • Check any orange markets nearby – these provide a trading option for clear-tested cattle from TB-restricted herds

Holding options and rules for TB-hit herds

AFU

There are three types of AFUs allowed in high-risk and edge areas – with grazing, without grazing and enhanced with grazing, which can take cattle from multi-TB-restricted and TB-free sources.

  • No pre-movement test to enter from TB-free herds. Clear test needed within 90 days for officially TB-free suspended or withdrawn (OFTS/W) herds
  • Often no surveillance testing
  • Cattle must go to slaughter or another AFU

Isolation unit

A cattle-proof and badger-proof building that can take cattle in from a single OFTS/W source.

  • A farm has six weeks to fill it and then it is closed
  • If the unit passes two consecutive 60-day tests, it can sell animals as ā€œclear-testedā€, regardless of what is happening with the main herd
  • They can be a separate business. If the main herd is shut down, the isolation unit can get ā€œswitched onā€

Temporary land associations

This is like a linked holding and is a good option for animals that you want to return to the main herd.

  • They have to be within 10 miles of the main holding and are classed as one epidemiological unit
  • This could be useful if heifers are reared off farm nearby
  • No pre-movement test is needed to move cattle between the units

Temporary county parish holdings (CPHs)

This arrangement is almost the opposite of a temporary land association. It is most suitable for cattle ultimately leaving the farm.

  • You need to do a pre-movement test to move between the two units and show biosecurity protocols are in place if sharing equipment/personnel
  • Two sites within one business could be separated with a temporary CPH
