Lameness affects approximately 10% of UK sheep at any time and causes chronic pain that significantly impairs welfare and production.
A lame sheep cannot graze effectively, compete for resources, or fulfill reproductive roles. Chronic lameness causes welfare compromise across months rather than days. Footrot is highly contagious and can spread through a flock within weeks of introduction. Prevention through routine footbathing, culling of chronically lame animals, and prompt treatment of new cases is far more effective and humane than treatment alone.
