June 2023 – Swine in Minnesota

Should we be concerned about the effect of sample handling on PRRSV detection by RT-qPCR?

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 this week’s Science, Iowa State researchers Page Berenice Munguía-Ramírez, Betsy Armenta-Leyva, Alexandra Henao-Díaz, Ting-Yu Cheng, Jianqiang Zhang, Gaurav Rawal, Fangshu Ye, Luis Giménez-Lirola and Jeffrey J. Zimmerman summarize three studies looking at the effect of temperature and time on the detection of PRRSV by PCR in serum, oral fluids and fecal samples.

Recent study pinpoints opportunities to better control swine flu

New research led by researchers at the University of Minnesota College of Veterinary Medicine (CVM) reveals that farmworkers vaccinating and weaning 3-week-old piglets can indirectly and significantly contribute to the spread of the influenza A virus (IAV) on swine farms. This information can help pig producers target biosecurity measures more strategically, curbing swine flu transmission and enhancing swine production outcomes.

Reducing Losses, Maximizing Profits: Examining Sow Mortality – A podcast

Swine mortality is a significant issue for the industry, as the death of an individual animal deeply affects farmers and the whole swine production. So in order to combat sow mortality and make production more profitable and sustainable, we must understand its causes. In this episode, Dr. Mariana Kikuti discusses a study conducted in the US Midwest on sow mortality in pig production systems, aimed at understanding the reasons for sow mortality and identifying factors associated with increased levels.

Best of Leman 2022: Mike Eisenmenger – Lateral infections and mitigations

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.

This presentation was originally given by Mike Eisenmenger of Swine Vet Center during the 2022 Allen D. Leman Swine Conference, recorded September 18, 2022.

Time for One Health: Do hog farms cause disease in North Carolina neighborhoods?

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 today’s Science Page researchers Kaushi Kanankege, Isaac Traynor, and Andres Perez re-examine the findings of a 2018 study, adjusting for other factors that can interfere wtih interpretation of the data.
