Sheep Lameness Welfare: A Preventable Crisis in Flock Management

Lameness is the most common and impactful welfare problem in sheep worldwide, causing widespread chronic pain that is disproportionately undertreated in most flock management systems.

Key Facts

Prevalence of lameness in sheep flocks averages approximately 10 percent but ranges from under 2 to over 30 percent depending on management
Footrot, caused by Dichelobacter nodosus, is the most common cause and causes characteristic tissue destruction and intense pain
Contagious ovine digital dermatitis has emerged as an increasingly important cause requiring specific management approaches
Affected sheep reduce grazing time, lose body condition, and show pain behaviors including frequent lying, limping, and knee walking
Treatment with antibiotics is effective for footrot but antibiotic choice, duration, and technique significantly affect outcomes
Five-Day Plan approach to footrot management has shown dramatic flock-level reductions in lameness prevalence
Vaccination against Dichelobacter nodosus reduces footrot incidence significantly in vaccinated flocks
Farmers who regularly assess their flocks for lameness and treat promptly achieve and maintain much lower lameness levels

Welfare Considerations

Sheep lameness represents one of the most widespread chronic pain problems in any farm animal species. Its acceptance as a normal part of sheep production in many farming cultures has created a situation where millions of animals live with painful foot conditions for weeks or months before treatment is provided. The pain from footrot is severe: tissue destruction between the digits causes constant, intense discomfort that prevents normal grazing and social behavior. Sheep cannot communicate pain effectively to observers using the obvious signals of larger animals, and their stoic behavioral responses mean lameness is often underestimated. Systematic approaches to lameness control demonstrate that prevalence below 2 percent is achievable, meaning most current lameness represents preventable, unnecessary suffering.

What You Can Do

Learn to recognize early lameness in sheep and treat promptly rather than waiting for severe clinical signs
Implement the Five-Day Plan approach to footrot management including examination, treatment, and recording
Vaccinate flocks against Dichelobacter nodosus in footrot-endemic areas to reduce flock-wide lameness prevalence
Cull chronic non-responding cases rather than allowing repeated treatment cycles without recovery
Target a lameness prevalence below 2 percent as the welfare benchmark for commercial sheep flocks
