Extreme Weather Contingency Plan

Guidance
  • HF.2.1 – Extreme Weather Contingency Plan is required on all units, including indoor and outdoor set-ups. It can be a standalone document or part of the Veterinary Health Plan.
  • HF.4 – In exceptional circumstances, it may be acceptable for there to be no dry lying area temporarily, in order to mitigate heat stress, e.g. when misters/sprinklers are used as part of the Extreme Weather Contingency Plan
  • HF.6.2 – For the purposes of the scheme, a cage is defined as an enclosure of bars and/or wires for keeping animals in. A tiered system, in which pigs are kept in 2 or more levels within the same airspace, is permitted provided the design meets the balcony system specification outlined in HF.6.5 and associated Appendix.
  • HF.9.3 – The Defra Code of Practice states that temporary crating systems should usually be opened within 4 days of farrowing, unless there is an overriding health or welfare reason to alter this. However, further research and commercial experience is needed to identify the optimum time at which to remove confinement and to develop best practice around these systems.
  • HF.9.5 – Acceptable nesting material includes, but is not limited to, wood shavings, shredded newspaper, straw, hessian sack/pieces, natural rope (ideally extending to the floor so the sow can push it along the floor).
