Sheep Dystocia: Welfare Management During Difficult Lambing in 2026

Dystocia (difficult birth) is a major source of acute suffering for ewes and lambs, requiring skilled stockmanship and appropriate veterinary assistance to minimise welfare harm.

Key Facts

Dystocia affects approximately 5-20% of ewes depending on breed, parity, and lambing management
Prolonged dystocia causes increasing trauma to both ewe and lamb, with vaginal and uterine damage common
Shepherd intervention within the first hour of active straining is critical for minimising welfare harm
Adequate nutrition and body condition scoring during pregnancy reduces dystocia risk substantially

Welfare Considerations

Dystocia causes acute, potentially severe welfare harm to ewes and lambs. Prolonged straining causes exhaustion, pain, and progressive trauma to the birth canal. Lambs presented in abnormal positions die from oxygen deprivation if not delivered promptly. Ewes with severe trauma may develop prolapse, metritis, or permanent injury. Skilled, timely intervention — ideally within 20-30 minutes of active straining without progress — dramatically reduces welfare harm compared to delayed or unskilled intervention. Stockperson training in lambing assistance, supported by clear protocols for veterinary referral, is the most important welfare intervention at lambing time.

What You Can Do

Ensure all lambing staff receive training in lamb repositioning and assisted delivery techniques
Establish clear protocols for when to seek veterinary assistance rather than persisting with difficult cases
Monitor ewes closely from the onset of active straining and intervene within 20-30 minutes if no progress
Maintain ewes in optimal body condition throughout pregnancy to reduce dystocia risk
