Sheep Lameness: One of Farming's Most Widespread Welfare Problems

Lameness affects a significant proportion of sheep in commercial flocks globally, causing chronic pain that is frequently undertreated due to detection difficulty and economic constraints.

Key Facts

Prevalence studies find lameness affecting 3-10% of sheep in UK flocks at any one time, with higher peaks.
Footrot (Dichelobacter nodosus) and contagious ovine digital dermatitis (CODD) are the most common causes.
Scald (Fusobacterium necrophorum) is a precursor condition that can progress to footrot if untreated.
Lame sheep lose body condition, have reduced reproductive performance, and experience chronic pain.
Pain recognition in sheep is challenging — they mask signs as a prey species anti-predator strategy.
The Five Domains Model identifies chronic pain from lameness as a significant negative welfare state.
Effective vaccines against footrot (Footvax) are available but require appropriate use protocols.
The AHDB's SCOPS (Sustainable Control of Parasites in Sheep) also addresses lameness reduction strategies.

Welfare Considerations

Sheep lameness is a welfare emergency that is normalized through its prevalence. A sheep hobbling on three legs may have been lame for weeks before a stockperson notices — in large flocks, individual inspection is infrequent. Research using pain scoring and grimace scales confirms that lame sheep experience significant chronic pain equivalent to what would prompt treatment in companion animals. Delayed treatment allows conditions to progress from treatable to chronic or irreversible. The financial disincentive of veterinary costs for low-value individual animals creates a systemic welfare failure. Training stockpersons to identify early lameness, treat promptly with appropriate antibiotics and pain relief, and cull chronic cases humanely is the foundation of welfare-responsible flock management.

What You Can Do

Support lamb and mutton certification schemes with verified lameness prevalence targets.
Advocate for mandatory lameness monitoring and treatment records in sheep farming.
If you farm sheep, implement a five-point lameness scoring system and treat within 3 days of detection.
Use appropriate antibiotics combined with NSAID pain relief for all treated lame sheep.
Vaccinate against footrot where Dichelobacter nodosus is endemic in your flock.
Cull chronically lame animals humanely rather than allowing prolonged suffering.
