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.

Report on the First African Swine Fever Case found in Greece in 2020

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 presenting a report by Bellou et al., from the Aristotle University of Thessaloniki, Greece on the first case of African Swine Fever discovered back in 2020.

Main Points 

  • In February 2020 the first African Swine Fever (ASF) case in Greece was diagnosed in a backyard swine farm.
  • Clinical symptoms were vague and necropsy findings could be attributed to other conditions, including ASF.
  • In areas neighboring high ASF-risk areas, ASF should always be included on the differential diagnosis, even in cases with mild symptoms, due to the high mortality rate and acute spread that ASF poses.

Pooling udder skin wipes to detect influenza in preweaning pigs

This is a recent publication from the Torremorell’s lab refining the use of udder wipes to detect influenza in preweaning pigs. It is available in the Journal of Veterinary Diagnostic Investigation.

Key points

  • Pooling of three, five, and ten udder wipes was evaluated.
  • Sensitivity decreased if the Ct count was above 31.5.
  • Pooling more than three udder wipes can affect the ability to detect influenza virus.
