ACMC Tip: Inter-Batch Hygiene
UK - Often rooms in piggeries which are managed on an all-in, all-out, system look clean during a superficial inspection.However, on closer examination there are frequently hidden reservoirs of infection which can reduce the benefits of the batch system, says Paul Thompson, veterinary consultant to pig-breeding company ACMC Ltd.
These result from inadequate cleaning of feeders (leaving stale food in the hoppers and troughs), insufficient cleaning behind feeders, exposed pipe-work and pen corners. Periodic cleaning beneath slats is also necessary to achieve the full benefits from the system.
Inspection of water systems often reveals large quantities of sludge in header tanks, so these should be cleaned out whenever possible.
After cleaning, all drinking points should be checked to ensure they are fully operational and delivering the correct water flow-rate.
Finally, vermin can be a major source of infection and will transfer diseases to subsequent batches of pigs. Where possible, fumigation of rooms may give additional control.
