Antimicrobial use in wean to market pigs in the United States assessed via voluntary sharing

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 wee, Drs. Peter Davies and Randall Singer from the University of Minnesota, share a summary of their publication on the use of antimicrobials in wean-to-market pigs in the United States.

Key Points

  • Obtained data on antimicrobial use in the US swine industry through voluntary and confidential sharing of proprietary data
  • First substantial description of antimicrobial use in US swine beyond FDA sales and distribution data  
  • Critically important classes were only 5% of use, and fluoroquinolones and ceftiofur (drugs of most concern) were <1%
  • The project is ongoing and seeking further participation from interested systems for 2018 to 2020.

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.
