Sheep Lameness Scoring and Prevention

Sheep lameness is a major welfare problem affecting millions of sheep annually, with systematic scoring and proactive management offering effective prevention.

Key Facts

Approximately 10% of UK sheep are lame at any given time, representing over 3 million animals
Lameness causes significant pain, reduces body condition, and impairs feeding and mothering ability
Contagious ovine digital dermatitis (CODD) has become the dominant cause of severe lameness in UK flocks
Footrot (Dichelobacter nodosus) remains a major lameness cause in wet conditions
Mobility scoring on a 0-3 scale enables systematic assessment and targeted treatment
The 3-day rule - treating lame sheep within 3 days of identification - significantly improves outcomes
Vaccination against footrot strains is effective where the correct serotype is used

Welfare Considerations

Sheep lameness causes prolonged, significant pain that reduces quality of life and welfare across millions of animals. Many sheep are observed to be lame without being identified and treated promptly. Systematic mobility scoring, prompt treatment protocols, and regular preventive management represent the most effective welfare interventions. A target of below 2% lameness prevalence is achievable and should be the industry standard.

What You Can Do

Implement a written lameness management protocol with your vet including target lameness prevalence
Learn mobility scoring techniques through courses from AHDB or Sheep Veterinary Society
Apply the 3-day rule - identify, treat, and record all lame sheep within 3 days of detection
Discuss footrot vaccination and CODD control with your flock vet annually
Support farm assurance standards that include lameness prevalence targets and monitoring requirements
