Understanding PRRSv diversity at the pig and litter level

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, Dr. Mariana Kikuti from the MSHMP team is sharing results from a study using whole genome sequencing to assess PRRSv diversity within and across litters.

Key points

  • Viral diversity within the piglet population is generally small, but higher diversity was found in ORFs 4 and 5a.
  • Within animal consensus changes were observed in a period as short as 2 weeks, which means piglets might be going to the GF sites with different viruses than the ones identified closer to farrowing.

Risk-based management of PRRS and PED

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.

Today, we are sharing the work of Dr. Kaushi Kanankege, post-doctoral associate in the VanderWaal lab.

Objective

We conducted a survey to determine swine industry perspectives on a) perceived importance of risk-modifying factors contributing to between-farm transmission of PRRS and PED, and b) prevention/mitigation measures that should be prioritized on a farm that was forecasted to be at high risk of breaking.
