Pig Weaning Age Welfare Science

Research consistently shows that weaning piglets too early causes significant welfare problems for both sows and piglets.

Key Facts

In the wild, piglets nurse for 12-17 weeks
Commercial weaning occurs at 3-4 weeks in many systems
Early weaning causes post-weaning diarrhea and increased susceptibility to disease
Extended weaning benefits gut development and reduces piglet mortality

Welfare Considerations

Early weaning severs the sow-piglet bond abruptly, causing distress in both. Sows continue to show signs of searching for piglets after early removal. Piglets weaned early show immune system immaturity leading to disease vulnerability and require more antibiotics. Extending weaning age to 4-6 weeks has clear welfare benefits and reduces antibiotic dependency.

What You Can Do

Support pig welfare standards that require minimum 4-week weaning ages
Advocate for weaning age requirements in national regulations
Choose pork from farms with stated weaning practices
Support research into welfare benefits of extended weaning in commercial pig farming
