Sheep Foot Rot: Prevention and Welfare Management

Foot rot is the most economically important and welfare-significant lameness condition in sheep. Effective prevention and prompt treatment reduce suffering across large numbers of animals.

Key Facts

Foot rot affects up to 10% of UK sheep in affected flocks and is caused by Dichelobacter nodosus
Severe foot rot causes the disintegration of the hoof and intense lameness that prevents normal grazing
The disease spreads through contaminated ground and is facilitated by wet, muddy conditions
Vaccination (Footvax) significantly reduces the incidence and severity of foot rot in vaccinated flocks
Prompt treatment with antibiotic injection at first recognition of lameness dramatically reduces progression
Footbathing with zinc sulphate or formalin reduces environmental bacterial load and aids healing

Welfare Considerations

Foot rot causes severe, disabling lameness that prevents normal feeding behavior. Lame sheep lose weight rapidly as their ability to compete for food and travel to pasture is impaired. The welfare burden of untreated foot rot is compounded by the fact that sheep instinctively hide lameness from predators — meaning visible lameness represents significant underlying pain. Prompt treatment reduces both the severity and duration of suffering for individual animals and the prevalence of disease across flocks.

What You Can Do

Inspect sheep feet regularly and treat lameness within 3 days of first observation
Vaccinate against foot rot (Footvax) according to manufacturer guidelines in affected flocks
Implement regular footbathing programs during high-risk wet periods
Cull persistently lame sheep that do not respond to treatment — they are a reservoir of infection and in chronic pain
Maintain quarantine for incoming sheep to prevent introduction of virulent strains
Provide dry, well-drained loafing areas to reduce wet underfoot conditions that favor disease spread
