Pig Neonatal Mortality: Prevention and Welfare

Piglet mortality in the first days of life is one of the most significant welfare problems in pig farming. Prevention-focused management dramatically reduces preventable deaths.

Key Facts

Neonatal piglet mortality averages 10-15% in conventional systems, with crushing by the sow accounting for approximately 50% of pre-weaning deaths
Prolific modern sow genetics produce litters of 14-20 piglets, but sows typically have 12-14 functional teats — smaller or weaker piglets may not secure a teat
Hypothermia is the second leading cause of neonatal piglet mortality — piglets are born with very little body fat and cannot thermoregulate
Providing a heated creep area away from the sow gives piglets a warm retreat that reduces crushing risk and hypothermia
Split suckling (dividing litters into groups that take turns nursing) ensures smaller piglets access the sow when competition is lower
Human supervision during the farrowing period significantly reduces mortality — farms with 24-hour farrowing supervision have substantially lower piglet losses

Welfare Considerations

Neonatal piglet mortality represents preventable suffering at scale. Each death involves an individual animal's experience, and the practices that prevent it — skilled supervision, appropriate temperature management, and welfare-conscious litter management — are well-understood. The pressure to breed ever-larger litters has created a biological mismatch where sow productivity exceeds her capacity to successfully raise all her offspring. Welfare-focused pig breeding programs are beginning to prioritize sow welfare and litter viability alongside litter size. Consumer demand for welfare-certified pork helps fund the supervision and management investment that reduces neonatal mortality.

What You Can Do

Support pork from farms with documented neonatal mortality monitoring and supervision protocols
Advocate for pig breeding selection that balances litter size with sow welfare and piglet viability
Ask retailers about farrowing welfare standards — supervised farrowing with 24-hour observation should be a minimum expectation
Reduce pork consumption or shift spending toward producers with comprehensive farrowing welfare programs
