Pig Neonatal Welfare and Sow Interaction

Neonatal pig welfare is shaped by sow behavior, housing design, and management interventions in the critical first days of life when mortality is highest.

Key Facts

Pre-weaning mortality in commercial pig production averages 10-20%, with crushing by sows the leading cause in crates
Sow confinement in farrowing crates prevents crushing but severely restricts natural nursing and maternal behavior
Free-farrowing systems allow natural nest-building and maternal behavior but require more careful management to prevent crushing
Research shows piglet vitality and survival are higher in free-farrowing systems when well-managed
Colostrum intake within 12 hours of birth is critical for piglet immunity and survival

Welfare Considerations

The farrowing crate represents one of the most contested welfare trade-offs in agriculture: it prevents crushing deaths but causes severe restriction of sow movement and behavior for 4-5 weeks. Sows in crates cannot respond to piglet calls, position optimally for nursing, or perform nest-building behavior. Free-farrowing systems protect sow welfare while requiring design features - guardrails, escape spaces for piglets - that reduce crushing risk. Several EU countries are phasing out farrowing crates, demonstrating that alternatives are commercially viable.

What You Can Do

Choose pork certified from systems with free-farrowing or enhanced farrowing systems
Advocate for farrowing crate bans with meaningful transition timelines for farmers
Support research into free-farrowing system design that optimizes both sow and piglet welfare
Ask retailers about farrowing system standards in their pork supply chains
Reduce pork consumption or choose plant-based alternatives to reduce demand for intensive systems
