Neonatal Lamb Welfare 2025: Survival and Care

A 2025 evidence review of neonatal lamb welfare during the critical first 48 hours of life, including hypothermia prevention, colostrum management, and dystocia response.

Key Facts

Neonatal lamb mortality averages 12-15% in UK flocks — most deaths occur within the first 3 days from hypothermia, starvation, trauma, or infection, making this the most welfare-critical period in sheep production.
Lambs are born with virtually no brown fat reserves and are at immediate hypothermia risk — ewes in poor body condition and cold, wet weather dramatically increase mortality risk.
Colostrum intake within the first 2 hours of life is non-negotiable for lamb survival — passive immunity transfer, energy provision, and gut closure all depend on early adequate intake.
Dystocia (difficult birth) in sheep causes oxygen deprivation, trauma, and hypothermia — trained shepherd intervention within 30 minutes of active labor is essential for welfare-acceptable outcomes.
The Glasgow Coma Scale for neonatal lambs classifies welfare status from vigorous to moribund — shepherds should assess all lambs within 30 minutes of birth using this tool.
Warming boxes for hypothermic lambs restore core temperature within 1-2 hours when combined with tube feeding and dry bedding — this saves lambs that would otherwise die painfully.
SCOPS (Sustainable Control of Parasites in Sheep) neonatal guidance integrates welfare, survival, and sustainability considerations into practical lambing management advice.

Welfare Considerations

Neonatal lamb welfare is primarily determined in the first 48 hours — preparation, skilled supervision, and rapid intervention save lives and prevent suffering. Every flock should have a lambing plan including colostrum banking, warming equipment, and dystocia training for all shepherds. The goal is zero preventable neonatal deaths, not merely acceptable mortality rates.

What You Can Do

Train all lambing staff in dystocia recognition, intervention technique, and neonatal assessment
Maintain a colostrum bank (frozen colostrum from first-milking ewes) for lambs born to poor-milking ewes
Install a warming box and tube feeding equipment before the lambing period begins
Assess all lambs within 30 minutes of birth using a neonatal vigor assessment protocol
