Learning how to recognize an FAD is critical to recognizing and reporting the disease early. It’s also important to demonstrate your pigs have no evidence of an infection so you can request a movement permit during an outbreak.
Sudden deaths with few lesions could be the first sign of an infection in a group of pigs. Other symptoms include:
Redness and blotching of the skin may also be seen, especially on ears, tail, legs, and ham. Bloody diarrhea may occur, as well as abortions in pregnant sows. Strongly consider carrying a thermometer and taking temperatures of sick pigs.
Recording your animal observations will help determine if you have increasing mortality or suspicious clinical signs that could be an FAD in your barn. If signs are observed, contact your manager or veterinarian. If you do not already have Daily Observation Logs you are using on your farm, you can find a form here.
Having an Emergency Action Plan helps everyone know who to call if they think their pigs may have an FAD. Clearly communicate to all caretakers if they are supposed to call their supervisor, herd vet, or State Animal Health Official in the event that they see something that may be an FAD.
A copy of an Emergency Action Plan can be found here.
Be sure to train your barn workers in all aspects of monitoring for the disease:
Being prepared by having everyone trained can help in several ways. It could help you identify the disease early on, minimizing spread to other animals/farms. It can also reduce the stress of barn workers if the plan for disease reporting has been clearly communicated. Make sure to document the training too.
