Sheep Lambing Welfare: Dystocia Management and Neonatal Support

Lambing is the most welfare-intensive period of the sheep year. Dystocia and neonatal failure cause significant suffering that is preventable through skilled management and appropriate intervention.

Key Facts

Ewes normally deliver lambs within 30-60 minutes of second-stage labour beginning; prolonged labour indicates difficulty
UK sheep breeds show wide variation in lambing difficulty, with terminal sires producing more dystocia
Mismothering is a significant cause of neonatal lamb mortality, particularly in large indoor lambing groups
Colostrum intake within 2 hours of birth is essential for passive immunity in lambs
Hypothermia is the leading cause of lamb death in extensively managed upland systems

Welfare Considerations

Ewes in prolonged dystocia experience intense abdominal pain as uterine contractions fail to deliver a malpresented or oversized lamb. Delayed assistance beyond 30-45 minutes of unproductive straining causes muscle fatigue, dehydration and increasing risk of uterine rupture or nerve damage. Neonatal lambs that fail to receive adequate colostrum suffer immune failure leading to days of illness before death. Hypothermic lambs in acute danger face a welfare emergency requiring immediate intervention. The scale of lambing in the UK sheep sector means that even modest improvements in intervention timing and neonatal support translate to significant aggregate welfare improvement.

What You Can Do

Implement a supervision protocol with defined intervention thresholds during the lambing period
Ensure stockpeople are trained in assisting difficult lambings with appropriate technique and equipment
Stockpile colostrum or synthetic alternatives for lambs unable to nurse from the ewe
Monitor neonatal lambs for colostrum intake, hypothermia signs and mismothering within the first 6 hours
Support sheep welfare training programmes that improve lambing management skills for new entrants to the sector
