Pre-weaning mortality in pigs represents both welfare failure and production loss, with evidence-based prevention reducing losses significantly.
Each piglet death represents a welfare failure - the neonatal period is when piglets are most vulnerable and their suffering before death is significant. Preventive interventions including adequate heating, creep areas that prevent crushing, good sow selection for maternal behaviour, and skilled stockperson monitoring are the most welfare-effective strategies for reducing neonatal mortality.
