Footrot is the most significant cause of lameness in UK sheep, causing severe welfare impacts that are largely preventable through vaccination and biosecurity.
Footrot causes severe chronic welfare impairment — affected sheep kneel to graze, lose body condition from reduced mobility and feeding access, and show clear pain behaviour. The welfare burden is substantial given UK sheep numbers — even a 3% lameness prevalence across 16 million sheep represents hundreds of thousands of animals in pain at any time. The welfare case for preventive vaccination is compelling: a twice-yearly programme can virtually eliminate footrot from a previously affected flock within 2 years. Prompt identification and treatment of lame sheep is the complementary immediate welfare response.
