Pig Farrowing Welfare: Birth and Early Life on Farms

The farrowing period — birth and early weeks of life for piglets — is one of the most welfare-critical phases in pig production, with confinement systems, piglet mortality and painful procedures generating significant concern.

Key Facts

Sows in conventional systems are confined in farrowing crates approximately 1 week before birth through 3-4 weeks of nursing
Farrowing crates measure approximately 0.6 x 2.2 metres — too small for the sow to turn around
Wild and free-range sows build nests before farrowing, a highly motivated behaviour frustrated by crate confinement
Litter sizes have increased through selective breeding: 12-16 piglets per litter is now common, exceeding the sow's 12-14 functional teats
Pre-weaning mortality in commercial systems ranges from 10-20%, primarily from crushing, starvation and hypothermia
Routine painful procedures performed without anaesthesia include tail docking, teeth clipping and surgical castration
The EU banned surgical castration without anaesthesia from 2022; most of Europe now uses immunocastration (Improvac) or local anaesthesia
Free-farrowing systems (Woehleretal, PigSAFE, UltraPro) allow movement while maintaining piglet protection — commercial adoption is growing

Welfare Considerations

The farrowing period involves significant suffering for both sows and piglets. Crate confinement frustrates the sow's powerful nesting drive — a highly motivated behaviour for which she is entirely unable to express, causing chronic stress and stereotypic bar-biting. Inability to move freely causes pressure sores and muscle atrophy over the 5-6 weeks of confinement. Painful procedures performed on piglets without anaesthesia — tail docking, teeth clipping, ear notching and castration — cause acute pain confirmed by vocalisation, cortisol spikes and avoidance behaviour. The high crushing mortality in conventional systems partly reflects the sow's inability to respond to piglet distress vocalisations in a crate — free-range sows crush fewer piglets despite greater movement freedom. Piglet pain from castration is a particularly acute welfare issue: surgical castration without analgesia is now recognised as causing severe pain equivalent to a comparably scaled procedure in humans.

What You Can Do

Choose pork, bacon and ham products certified to higher welfare standards: RSPCA Assured, Outdoor Bred, Free Range or Organic
Support campaigns to ban farrowing crates — Denmark, Germany, Netherlands and Sweden have either banned or set phase-out dates
Ask your supermarket about farrowing crate policies — corporate procurement commitments drive faster change than regulation alone
Support Compassion in World Farming's campaigns on farrowing crates and painful piglet procedures
Advocate for mandatory anaesthesia and analgesia for all surgical procedures on pigs, including castration
Consider reducing pork consumption or substituting plant-based alternatives to reduce demand from worst-welfare systems
