Execute and Monitor Solutions

When a swine disease strikes, you want helpful information immediately. Fortunately, there’s SOURCE, a systematic approach to disease control, prevention and management using a step-by-step process developed by Boehringer Ingelheim.

Once your preferred solution options are clearly outlined, you can determine which one(s) should be executed to help achieve your goal of eliminating, diminishing or preventing PED on your farm. This is the sixth and final step in the SOURCE process – “execute and monitor solutions.”

Execution techniques

You now have designed your solutions. Now it’s time to execute. Follow these strategies to best execute your solutions and best meet your goal:

  1. Obtain team commitment to work toward same solution
    1. Clearly communicate the plan to all farm personnel.
    2. Emphasize why the plan, and each step in it, is important.
    3. Provide any necessary and ongoing training.
  2. Develop metrics to track results. Communicate to the team what should happen and when it should happen.
  3. Maintain team focus through consistent collaboration. What’s worked? What hasn’t worked? What should change?
  4. Review the plan regularly with herd veterinarian.

Monitoring tactics

You’ve done all this work, stated your herd goals, and implemented your solutions. Now it’s time to measure to see if you are succeeding.


  • Only introduce PED-negative animals when you are ready to avoid having to start over.
  • Do not introduce PED-negative animals until you have had three negative environmental PCR tests and three consecutive negative animal tests.
  • Continue monitoring, working with herd veterinarians, and following biosecurity protocols.


  • Ensure that you are not bringing negative animals into a positive herd. Doing so results in a chronic infection situation.
  • Ensure that replacement animals are being adequately acclimated to the PED virus in your herd.
  • Measure the immune response in replacement animals two to three weeks after exposure to the virus.
  • Routinely measure virus circulation in due-to-wean pigs.
  • Continue monitoring, working with herd veterinarian, and following biosecurity protocols.


  • Always ensure that replacement gilts are truly negative.
  • Keep a scrupulous focus on biosecurity protocols, and ensure they are being followed.
  • Be keenly aware of PED status in your proximity.
  • Continue monitoring, working with herd veterinarian, and following biosecurity protocols.

Everyone can help

There’s no shame in being a PED-positive farm. In fact, more than 60 percent of sow herds in the United States have been positive at one time or another. While it may take time and commitment from the entire pork industry to eradicated PED, it is possible to do so in the United States. It is critical that every stakeholder in the industry – farmers, veterinarians, feed suppliers, packers, transportation companies, etc. – understand how the virus is transmitted and their responsibilities to minimize its spread.

Communication is critical – as a pig farmer, you can talk to all outside visitors (gas company, trash hauler, mail delivery, etc.), as well as surrounding farms, to know and understand where PED exists and how it spreads. With this knowledge, delivery routes can be modified and allied industry can focus its efforts.
