Lameness is the most common health and welfare problem in sheep, affecting up to 10% of UK sheep at any time and causing chronic pain.
Lame sheep experience chronic pain that affects movement, feeding, and social behaviour. Pain suppression through stoicism means many affected animals are not identified until severely affected. Treatment is often delayed because examining individual sheep in large flocks is labour intensive. Untreated lameness causes muscle wasting, reduced nutrition, and compromised immunity. The cumulative welfare burden across the UK sheep population is substantial.
