Post-epidemic dynamics of PEDV in the United States: Current trends and patterns

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, the MSHMP team is sharing what they are observing regarding Porcine Epidemic Diarrhea virus in the US. What are the trends and patterns emerging years after the epidemic?

Main Points

Since July 2014, the number of PEDV yearly outbreaks reduced both numerically and in geographical distribution.
PEDV outbreaks occur seasonally, with most cases being detected during winter.
Spatial-temporal clusters of PEDV outbreaks were detected, most of which occurred prior to 2019.

Porcine epidemic diarrhea (PED) is a swine enteric viral disease first documented in the U.S. swine population in 2013, at which time it sparked a major epidemic. Since then, PEDV has persisted in the U.S. breeding herd with low incidence during the post-epidemic period. Despite continued monitoring and surveillance, there is minimal research and understanding of the endemic phase of PEDV in the country. Our objective was to characterize PEDV in the U.S. breeding herd in the post epidemic period (spatial-temporal distribution of cases and associated factors).

Best of Leman 2021 #1: Josh Rennells – Clemens Food, a unique approach to creating value

This is our most popular series on the blog. Once a month, we are sharing with you a presentation given at the Allen D. Leman swine conference, on topics that the swine group found interesting, innovative or that lead to great discussions.

You can find all of the presentations selected from previous conferences on the blog here.

We are starting the 2021 edition with one of our keynote speakers, Josh Rennells, CFO of the Clemens Food Group shares insights into his company unique approach to creative value for the producers and the consumers.

PRRSV 144 L1C: A Rapid Response to a National Crisis

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.

In partnership with Boehringer Ingelheim Animal Health USA Inc., Pipestone Research has provided a rapid response to bring science-based answers to managing the emergence of PRRSV 144. Based on field observations from practitioners and producers, stating that, “This is the worst strain of PRRSV ever,” “Vaccines don’t work anymore”, and “Biosecurity protocols are ineffective,” the team determined that immediate action was needed.

Environmental footprint of pork production discussed

This article was written by Dr. Pedro Urriola, faculty member at the University of Minnesota, published on the National Hog Farmer website on October 14th, 2021.

Days started to be shorter and cooler as the fall season was upon us and with that came the Allen D. Leman Swine Conference and the Minnesota Nutrition Conference. This year, both conferences expanded discussions on the topic of environmental and business sustainability in the pork industry, among other relevant topics. Critical conversations are happening at public institutions, among investors, packers, retailers, and as consumers are demanding a reduction in the environmental impact of animal protein production. This reduction in the environmental footprint of pork production is a goal well understood and actively pursued by pork producers.

Keeping PRRS 144 Out of Sow Herds: a podcast

Podcasts are a perfect way to get caught up with new swine information! We are presenting you the latest episode from “At The Meeting… Honoring Dr. Bob Morrison” in collaboration with SwineCast.

The emergence of PRRS 144 has increased the risks of breaks in sow herds.

Dr. Karyn Havas (Pipestone Research) and Dr. Mariana Kikuti (University of Minnesota) join The ATM team (Dr. Montserrat Torremorell – College of Veterinary Medicine, University of Minnesota, Dr. Gordon Spronk – Pipestone Veterinary Services, and Dr. Tom Wetzell – Swine Veterinary Consultant) to identify what producers can do to reduce the threat.
