Dystocia (Difficult Birth) in Sheep: Welfare Emergency Management

Dystocia is a leading cause of death in ewes and lambs at lambing. Rapid recognition and skilled intervention prevents prolonged suffering and saves lives.

Key Facts

Dystocia (difficult birth) affects approximately 5-10% of ewes, with higher rates in breeds with oversized lambs
Common causes include oversized single lambs, malpresentation, and uterine inertia
Prolonged dystocia causes fetal hypoxia, lamb death, and life-threatening uterine damage in the ewe
Ewe mortality from untreated dystocia is significant -- ruptured uterus and infection are common sequelae
Vaginal prolapse is a related condition requiring immediate intervention
Assisted delivery using lubrication and careful repositioning resolves most cases if intervened promptly

Welfare Considerations

Dystocia causes acute intense pain in ewes from prolonged uterine contractions against an obstruction. Fetuses in prolonged dystocia experience hypoxia and distress. The longer intervention is delayed, the worse welfare outcomes for both ewe and lamb. Experienced shepherds who recognize early signs of dystocia and intervene within 30-60 minutes of second-stage labor without progress dramatically improve outcomes. Cesarean section is necessary for unresolvable cases and requires appropriate anesthesia and analgesia. Post-intervention pain management including NSAIDs is essential for welfare recovery. Careful monitoring of all ewes during lambing is the foundation of dystocia management.

What You Can Do

Intervene in any ewe that has been in active second-stage labor for over 30 minutes without delivery
Ensure adequate lubrication before any assisted delivery attempt
Have veterinary contact available during lambing season for cases requiring caesarean
Administer NSAIDs after assisted deliveries as standard welfare practice
Train all lambing staff in dystocia recognition and basic intervention techniques
