What do US producers and veterinarians think about antibiotic-free production?

This recent open-access publication in Frontiers expends beyond the realm of swine production and raises the question raising animals without using antibiotics. Dr. Singer from the University of Minnesota in collaboration with multiple other institutions surveyed US producers and veterinarians to gather their thoughts on the topic.

Comparison of PRRS incidence rate in status IV breeding herds during 2009-2019

This post is from the MSHMP team looking at status IV farms and their PRRS incidence between the years 2009 and 2019. Quick reminder, in 2011, Holtkamp et al. defined status IV farms as PRRS-negative per their shedding and exposure status.

Key points

  • PRRS incidence rate in status IV farms varied significantly from 2009 to 2019.
  • The incidence rate in status IV farms during 2019 was one of the lowest on record and comparable to the one observed in 2013 and 2014; the years of the PED epidemic in the US.
  • PRRS incidence in status IV farms during 2019 was significantly lower than the one of 2015 and 2016 and marginally non-significant lower (p=0.07) than the one of 2018.

Aerosol Detection and Transmission of PRRSv: What Is the Evidence, and What Are the Knowledge Gaps?

Aerosol transmission of Porcine Reproductive and Respiratory Syndrome virus is a major issue hog producers have had to deal with for several decades now. It encouraged the development of air filtration systems in farrow-to-wean farms as well as the isolation of high-value genetic lines in remote areas. This new publication, a collaboration between Dr. Arruda at the Ohio State University and Drs. Corzo and Torremorell from the University of Minnesota is a review of our knowledge of how PRRS is transmitted via aerosol.

How investigating the piglet helps us advance influenza control

Before we start with today’s post, we would like to wish you all the best for this new year. Thank you for your support and for reading us year after year.
So here is to a new decade, always bringing you science-driven solutions!

Weaning-age piglets are responsible for the spread of many diseases, but in the case of influenza, they are also responsible for circulating the virus within the herd.
