Sheep Weaning Welfare: Evidence-Based Management of Ewe and Lamb Distress

Weaning causes acute stress in both ewes and lambs, with vocalisation, reduced feeding, and behavioural agitation indicating significant welfare impacts that management can substantially reduce.

Key Facts

Abrupt weaning causes 24-72 hours of intense vocalisation and distress in ewes and lambs
Gradual or fence-line weaning reduces stress compared to complete separation
Lambs weaned from 10-12 weeks show less stress than those weaned earlier
Providing familiar companions during weaning reduces isolation stress
Ewes with higher milk production show greater distress at weaning due to udder engorgement

Welfare Considerations

Weaning represents one of the most acute welfare challenges in sheep production, causing measurable physiological and behavioural stress in both ewes and lambs. Abrupt separation triggers persistent vocalisation, reduced feed intake, weight loss, and elevated stress hormones in both parties. Ewes with heavy milk production experience painful udder distension. Management practices that allow gradual separation, fence-line contact, or later weaning age substantially reduce welfare impact. The welfare case for gradual weaning is strong and should be incorporated into sheep production codes of practice.

What You Can Do

Implement fence-line weaning where ewes and lambs can maintain contact while reducing milk intake
Avoid weaning before 10-12 weeks of age where flock management permits
Provide lambs with familiar companions when separating from ewes to reduce isolation stress
Monitor ewes with high milk production for udder engorgement and treat mastitis promptly
Adopt gradual weaning protocols into farm management plans as a standard welfare improvement
