History and best practices of captive bolt euthanasia for swine

This week, we are sharing a literature review based on a collaboration between Drs. John Deen and Perle Zhitnitskiy and the animal welfare team at the University of Wisconsin River Falls, led by Dr. Kurt Vogel. In this open-access publication from the Journal of Translational Animal Science, the authors review the history of captive bolt euthanasia, best practices and current challenges faced by the swine industry including the euthanasia of mature swine.

How is manure changing over time? Trends in Midwest manure sample data

This post comes from our colleagues at the University of Minnesota -College of Extension. Follow their latest news on their blog: Minnesota Crop News

This post was written by: Nancy Bohl Bormann, Graduate research assistant; Melissa Wilson, Extension manure management specialist, & Erin Cortus, Extension engineer

Key Points

  • Current livestock manure “book values” (the approximate amounts of various nutrients in manure) are several decades old.
  • Using recent data from several Midwest U.S. labs, we found that manure nutrient data have changed over time compared to previous Midwest Plan Service (MWPS) manure book values.
  • The University of Minnesota is creating a manure nutrient database called ManureDB to help update these values.
  • We are currently looking to partner with laboratories that analyze manure on this project.

Active surveillance and impact of an intervention on PEDV occurrence in a large pig production system in the US

Today, we are sharing a recent publication from the MSHMP team led by Dr. Cesar Corzo in collaboration with a US pork producer. The full article is available in open access on the Porcine Health Management journal’s website. The objectives of this study were to actively monitor Porcine Epidemic Diarrhea in pigs during several stages of the finishing phase and to assess the impact of added biosecurity measures.

Evidence of influenza A infection and risk of transmission between pigs and farmworkers

Today, we share a recent study by the Torremorell’s lab published in open access, in the Zoonoses and Public Health journal this past month. Led by Dr. Gustavo Lopez, this work focuses on the interface between the pigs and farmworkers when considering influenza A infection.

Persistence and shedding of Senecavirus A in naturally infected boars

In this recent publication from the Journal of Veterinary Diagnostic Investigation, Dr. Matt Sturos from the UMN Veterinary Diagnostic Lab shares a case report establishing the shedding of Senecavirus A through boar semen. This study highlights the importance of considering semen as a potential biosecurity risk in the case of a Senecavirus A outbreak.
