This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.
This week, we are sharing an article by Dr. Amber Stricker from Suidae Health and Production, published in PigHealthToday.com
“Over the years, there’s been considerable progress in the development of strategies aimed at eliminating porcine respiratory and reproductive syndrome virus (PRRSV). I define successful PRRSV elimination as the absence of clinical disease in the breeding herd and, more importantly, the absence of the vertical transmission of virus to weaned pigs. Unfortunately, successful PRRS elimination isn’t always achieved in some herds, and I have several experiences that may help answer why.”
Dr. Stricker then compiles six reasons that, in her experience, led to a failure in PRRS elimination:
- No break in disease cycle or insufficient herd closure
- Incomplete exposure
- Compliance problems
- Holding back pigs
- New virus introduction
- Insufficient diagnostics
Take a look at the full article to read more about each of those facors.
