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

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, 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.
