Behavioral insights impacting preweaning mortality

Abstract

This study highlights the critical role of production factors in influencing sow posture behaviors and piglet survival. Analyzing average posture durations for different time in a day, before and after farrowing, crate designs, and heat lamp configurations revealed that high-mortality sows had shorter sternal lying events; lower parity sows were more active; crate type and heat lamps impacted posture events; and post-farrowing days increased lying durations, while pre-farrowing days showed longer standing durations. This research provides valuable insights for improving management practices, aligning factors with sow needs to reduce piglet mortality, enhance maternal welfare, and support sustainable swine production.
