Pig Weaning Age and Welfare

Commercial pig farming weans piglets at 3-4 weeks, far earlier than the natural 12-17 week weaning in wild pigs.

Key Facts

Piglets naturally suckle for 3-4 months in free-ranging conditions
Early weaning causes acute distress, gastric ulcers, and immune compromise
EU regulations require minimum 28-day weaning age
Voluntary schemes allowing later weaning at 35+ days show improved welfare

Welfare Considerations

Early weaning is one of the highest-impact welfare issues in pig farming. The abrupt separation from the sow causes acute psychological distress and leaves piglets immunologically vulnerable. The week after weaning is associated with peak illness and death rates in commercial systems.
