Swine in Minnesota

Measures of disease occurrence review

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.

The MSHMP weekly report contains the graphic representation of the occurrence and dynamics of specific swine pathogens using epidemiologic tools that measures of disease occurrence such as, prevalence, cumulative prevalence and incidence. In this science page we would like to reacquaint our audience with a few of these tools.

Porcine Reproductive and Respiratory Syndrome Viral Diversity within a Farrow-to-Wean Farm Cohort

Today we are sharing a recent publication from the MSHMP team in collaboration with the VanderWaal and Schroeder’s labs. The objective of the study was to assess the diversity of PRRS genomes within a cohort of naïve pigs undergoing a PRRS outbreak. The full paper is available online in open access.

Review of MSHMP PRRS Chart 2 ‐ Prevalence

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.

Key Points:

• Chart 2 depicts the prevalence (i.e., the proportion of breeding herds in each of the PRRS status categories over time).

• Since 2013, the proportion of farms that vaccinate (2vx) and that use field virus (2fvi) has not changed dramatically.

• The cyclical pattern of farms in status 1 observed early in the project is slowly disappearing after 2018.

Hear from industry leaders at the 2023 Allen D. Leman swine conference!

Here is a quick snapshot of the amazing talks that will be happening this year at the Allen D. Leman swine conference. We hope to see you there!

Best of Leman 2022: Paul Yeske – Recirculation of M. hyopneumoniae in previously immune animals

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.

The 2023 Allen D. Leman swine conference is less than a month away. Register here!
