Pig Neonatal Welfare | Animal Welfare Hub

Neonatal piglet welfare encompasses crushing mortality, temperature management, colostrum access, and processing procedures that collectively determine early life outcomes in commercial pig production.

Key Facts

Pre-weaning piglet mortality from crushing by the sow averages 10-15% in commercial systems — the leading cause of piglet loss
Hypothermia is a major cause of neonatal piglet death — piglets have limited thermoregulatory capacity at birth
Colostrum intake within 12 hours of birth is essential for passive immune transfer that protects piglets from disease
Castration, tail docking, and teeth clipping are routinely performed on piglets within days of birth
Farrowing crates that restrict sow movement reduce crushing mortality but prevent natural maternal behaviors
Free farrowing systems allowing sow movement achieve comparable mortality rates to crates with appropriate management
Low birth weight piglets — runts — have significantly higher mortality and welfare challenges throughout production

Welfare Considerations

Neonatal pig welfare involves welfare trade-offs between sow welfare and piglet welfare that have no perfect solution. Farrowing crates prevent the sow from expressing natural movement and nesting behavior — significant welfare harms — while reducing crushing mortality of piglets. Free farrowing systems resolve sow welfare but require more skilled stockmanship to achieve equivalent piglet survival. Both sow and piglet welfare can be achieved simultaneously in well-managed free farrowing systems, but this requires investment in design and training. Processing procedures in the first days of life — tail docking, castration, teeth clipping — cause acute pain when performed without analgesia, which is the norm in most commercial systems. The welfare case for mandatory pain relief for all neonatal piglet procedures is clear and the regulatory lag represents a significant ongoing welfare failure in commercial pig production.

What You Can Do

Support regulatory requirements for pain relief during all neonatal piglet processing procedures
Advocate for investment in free farrowing system development that achieves both sow and piglet welfare goals
Choose pork from certified systems requiring enriched farrowing that provides sow behavioral freedom
Support research into free farrowing system designs achieving piglet survival equivalent to farrowing crates
Reduce pork consumption from conventional systems and shift toward certified higher welfare products
Encourage veterinarians to promote and supply pain management protocols for neonatal pig procedures
Support producer training programs improving stockmanship skills needed for welfare-positive free farrowing management
