Stepping-up the biosecurity on your swine operation
Even though outside temperatures feel like summer, fall is just around the corner and swine producers need to be thinking about their biosecurity protocols. Biosecurity management practices have two main goals for protecting your herd. The first is preventing a disease from entering your operation and the second if a disease does enter it is to prevent the spread of the disease throughout your operation. With a new disease, PEDV (porcine epidemic diarrhea virus), infecting swine operations and the increase of PRRS (porcine reproductive and respiratory syndrome) in the fall, swine operations are going into an unknown fall and need to step-up their biosecurity.
Here are some important biosecurity measures to remember:
-Before bringing new animals into the herd, they should be isolated for 30 days and tested before being allowed into the herd. Even healthy looking animals may be shedding pathogens.
-Limit the number of people being allowed into the barns and make sure they have had sufficient downtime when going between different swine operations. For those individuals unfamiliar with biosecurity (e.g. electricians and plumbers), remind them to not be around other pigs before entering your facility and that all tools should be disinfected if they have been used at another swine operation.
-All operations need to have a “clean-dirty line”. This is a place where outside clothes are removed and barn clothes are put on to ensure that a disease will not be brought in through the employee’s clothes or shoes. Sow farms should also have shower-in and shower-out policies to ensure that no disease spreads into the farm.
-After animals are removed from a room, the room should be washed with hot water, disinfected, and allowed to dry before allowing new animals to enter.
-Keep your barn and surrounding areas clean. Domestic and wild animals should be kept out of the barn because they can spread disease. Limiting their access to food and water and keeping a clean environment will alleviate this problem. Netting and mesh covering should be used to keep out birds especially on naturally ventilated buildings.
-All transport trailers need to thoroughly washed with hot water, disinfected, and allowed to dry before returning to your operation. Recent studies have shown that PEDV can be tracked onto the trailer when drivers are unloading pigs.
-If possible, delivery trucks that are bringing supplies to your operation should only arrive once a month or have them delivered to your house. Delivery personal are not aware of proper biosecurity measures and could track a disease to your farm from one of their other stops.
