Pig Welfare and Weaning Age Science

Weaning age significantly affects pig welfare. Current commercial weaning at 3-4 weeks is earlier than natural weaning and causes significant stress. Research supports later weaning for welfare.

Key Facts

Natural weaning in pigs occurs at around 12-17 weeks under semi-natural conditions
EU legislation requires minimum weaning age of 28 days with exceptions
Weaning at 28 days causes less stress than weaning at 21 days in research studies
Later weaning improves piglet immunity, gut development, and reduces antibiotic need
The economic case for later weaning is improving as antibiotic reduction incentives increase

Welfare Considerations

Early weaning is one of the most significant welfare compromises in commercial pig production. Evidence consistently shows that later weaning reduces stress and disease. Economic barriers to later weaning are declining as the antibiotic-welfare link becomes clearer.
