Experimental pig study confirms the high virulence of the recently emerged PRRSV 1-4-4 L1C variant strain

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 we learn about the findings of a study conducted by researchers at Iowa State University inoculating pigs with the 1-4-4 L1C variant.

Summary: A putative PCV3-associated disease in piglets from Southern Brazil

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 look at the results of a joint study between the Universidade Federal Do Rio Grande Do Sul, Agroceres Pic and the UMN Veterinary Diagnostic Laboratory that looked at the connection between newborn piglets presenting with large caudally rotated ears and PCV3 infection.

Best of Leman #5: J. Ross – Current efforts towards improving pig livability

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.

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

Development of an automated model to capture and analyze whole-herd parameters associated with wean-to-finish mortality

This week, Dr. Linhares’s team from Iowa State University is proposing a model to analyze wean-to-finish mortality based on whole-herd parameters such as farrowing rate, PRRS status or even management factors.

Key Points

An automated model was developed to consolidate multiple data streams from weaning cohorts to their respective closeouts.
Sow farm productivity and health are highly associated with wean to finish mortality.
Sow farm-related data explained 74.1% of the variation observed on wean to finish mortality.

Best of Leman 2017 series #8: B. Thompson – 25 years of experience in sow health and longevity

We launched a new series on the blog in October. Once a month, we are sharing with you a presentation given at the 2017 Allen D. Leman swine conference, on topics that the swine group found interesting, innovative or that lead to great discussions.

Our 8th presentation is by Dr. Bob Thompson, the 2017 recipient of the Science in Practice award, regarding 25 years of experience in sow health and longevity.
