Advanced Sheep Lameness Management

Lameness is the most significant welfare problem in sheep production globally, and systematic prevention and treatment programs can dramatically reduce suffering across flocks.

Key Facts

Lameness affects approximately 10 percent of sheep in UK flocks at any given time, with variation from 2-30 percent
Footrot caused by Dichelobacter nodosus is the most common cause of severe lameness in sheep worldwide
Contagious ovine digital dermatitis has emerged as an increasingly prevalent lameness cause in recent years
Lame sheep show reduced feeding, social withdrawal, and altered posture indicating significant pain
The Five Point Plan for sheep lameness offers a systematic approach to achieve less than 2 percent lameness
Prompt treatment within 3 days of detecting lameness dramatically improves outcomes versus delayed intervention
Vaccinations against footrot strains can reduce flock-level lameness by 70-80 percent in endemic areas
Genetic selection for footrot resistance offers long-term prevention potential in breeding programs

Welfare Considerations

Sheep lameness represents one of the highest-priority welfare issues in the sheep industry, combining high prevalence with significant, prolonged pain that substantially impairs quality of life. Research using pain assessment tools confirms that lame sheep experience genuine suffering that affects feeding, social interaction, and movement. The Five Point Plan and similar systematic approaches demonstrate that lameness prevalence can be driven below 2 percent — far below the 10 percent average — through combination of prompt treatment, vaccination, selection, quarantine, and culling of chronic cases. The gap between achievable and average lameness rates represents enormous preventable suffering. Economic analysis also shows that lameness control is profitable, removing the argument that welfare improvements are unaffordable.

What You Can Do

Implement the Five Point Plan or equivalent systematic lameness control program on sheep farms
Train farm staff to detect lameness early — treat within 3 days of first detection for best outcomes
Use footrot vaccination programs in areas with endemic disease
Cull or isolate chronically lame sheep that do not respond to treatment
Incorporate footrot resistance into breeding decisions to reduce genetic susceptibility over time
Work with a flock veterinarian to establish a written lameness control protocol with monitoring targets
