Understanding PRRS control best practices in the US swine industry

September 22, 2016

Porcine Reproductive and Respiratory Syndrome (PRRS) is a complex disease. PRRS control requires working with a set of tools around whole-herd immunity and bio-management practices.

A new study at Iowa State University will identify a more tailored approach to PRRS management, identifying the best ways for our industry to manage the virus and help reduce the costly reproductive and performance losses it brings.

To help find the best practices for individual operations, a postgraduate fellow will be working with other Iowa State University scholars over a two-year period to evaluate at least 135 breeding herds and a few factors that make PRRS challenging to manage.

  • Complexity of the virus. This includes such variations as PRRSv immunology, variations in infection and virus survival time.
  • Variations in pig production systems. Each herd has its own unique set of challenges, which could include variations in herd size, pig flow, barn layout, gilt acclimatization protocols and herd PRRSv immunity.
  • Variability in adopted practices to eliminate and control the virus. This also comes with variability in efficacy of PRRSv control programs.

 The study will help us understand the connection between individual breeding herd characteristics and PRRS management. This can help put us one step closer to eliminating PRRSv nationwide.
