Sheep Wean Age Welfare Science

The age at which lambs are weaned significantly affects both lamb and ewe welfare, with research supporting later weaning in most production systems.

Key Facts

Commercial lambs are typically weaned at 10-16 weeks in many production systems
Natural weaning in sheep occurs at 4-6 months, much later than commercial practice
Abrupt weaning causes significant behavioral and physiological stress in both lambs and ewes
Gradual weaning or extended suckling periods reduce stress responses measurably
Ewe body condition and grassland management influence optimal weaning age in practice

Welfare Considerations

Weaning age is a welfare lever that can be adjusted with relatively modest management changes. Research consistently shows that later weaning reduces stress and improves welfare outcomes - making it a practical target for welfare improvement in commercial sheep production.

What You Can Do

Support sheep farms adopting later weaning as a welfare improvement measure
Advocate for weaning age guidance in sheep welfare certification standards
Choose lamb from farms demonstrating welfare-conscious weaning practices
