Pig Neonatal Welfare and Survival

Neonatal pig survival is a critical welfare metric, with significant mortality in the first 72 hours reflecting management quality and highlighting welfare priorities for early life care.

Key Facts

Pre-weaning mortality averages 15-20% in commercial pig production globally
Crushing by the sow accounts for approximately 50% of pre-weaning deaths
Low birth weight piglets (under 1 kg) have significantly higher mortality and chronic welfare disadvantages
Adequate colostrum intake within the first 6-12 hours is critical for survival and immunity
Selective breeding for larger litters has produced more piglets than sows can effectively nurture

Welfare Considerations

Neonatal pig welfare is a systemic challenge created partly by the genetics of modern pig production. Selection for large litter sizes has produced more piglets per litter than sows can reliably nurse, resulting in competition, malnutrition, and crushing deaths that represent significant welfare harm. Reducing pre-weaning mortality requires both genetics (moderating litter size selection) and management (ensuring adequate colostrum access for all piglets, management of low birth weight individuals, monitoring of sow-piglet interactions in the critical first hours). The welfare imperative is clear: each pre-weaning death represents welfare failure for that individual, and preventable deaths represent management failures.

What You Can Do

Support breed improvement programs that moderate litter size to match sow nursing capacity
Advocate for pre-weaning mortality to be a required welfare metric in pig production certification
Support management protocols that ensure all piglets receive adequate colostrum in the first hours of life
Choose pork from producers who publish welfare metrics including neonatal mortality rates
Support research into interventions that reduce pre-weaning mortality across different housing systems
