Now that we know how to keep diseases from entering our farm, let us learn about what to do when the disease is already present inside the farm. This is what constitutes internal biosecurity, which we will learn through this module.<\/p>\n<\/div>

Animal Movement\/Pig Flow<\/h3>\n
Mixing animals from different age groups and stocks can risk the health of susceptible animals, so it is important to implement controlled animal movement and strict pig flow. All-in-all-out (AIAO) pig flow provides the highest internal biosecurity. It breaks the transmission cycle of diseases from one group to another, unlike continuous flow, where new additions bear the disease burden of the animals already present.<\/p>\n
AIAO Protocol:<\/p>\n
\n- Purchase animals or farrow them in groups that appropriately fit the facility and contain them in a specific facility\n
\n- NOTE: Do not mix purchased and far-born animals; purchase all animals from a single source <\/em><\/li>\n<\/ul>\n<\/li>\n
- When animals in a group are ready for market, move all of them out at the same time\n
\n- NOTE: Do not hold back and mix runts\/tail-enders, but if they are held back, keep them at a separate facility away from the next group<\/em><\/li>\n<\/ul>\n<\/li>\n
- After the group has moved out, remove the bedding (if any) then clean the facility with warm water using a pressure hose to remove all dirt and manure from cracks, crevices, feeders, walls, ceiling, water troughs, penning, and flooring; use steam cleaner wherever possible for efficient cleaning<\/li>\n
- After cleaning, disinfect the facility with a suitable disinfectant solution.<\/li>\n
- Allow two weeks between cleaning the facility and moving a new group into it.<\/li>\n
- For hoop-houses, spread a layer of agricultural limestone or ag-lime before placing fresh bedding<\/li>\n<\/ul>\n
