Orphan Lamb Welfare and Management

Orphan or rejected lambs require careful management to ensure adequate nutrition, social development, and welfare outcomes comparable to dam-reared lambs.

Key Facts

Up to 5% of lambs require supplementary or artificial rearing each year
Colostrum intake within 6 hours of birth is critical for passive immunity and survival
Artificially reared lambs can develop behavioural problems if raised in isolation
Group lamb rearing with ad libitum milk replacer improves welfare outcomes
Early weaning stress is significant and requires careful management

Welfare Considerations

Orphan lambs face multiple welfare challenges: reduced passive immunity without adequate colostrum, social isolation in individual pens, and nutritional deficiencies if milk replacer is incorrectly formulated. Group rearing of orphan lambs on shared milk feeders provides social interaction and reduces stereotypic behaviours compared to individual rearing. Ensuring adequate colostrum from a stored supply within the first 6 hours is the single most important welfare intervention for newborn orphan lambs.

What You Can Do

Maintain a frozen colostrum bank for emergency use with orphan lambs
Rear orphan lambs in groups rather than individually where possible
Use automatic lamb feeders to allow ad libitum milk access
Monitor orphan lamb growth and behaviour to detect welfare problems early
