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.
