Sheep Lameness: Pain, Detection, and Prevention in Flocks

Lameness is one of the most prevalent and painful conditions in sheep, yet it remains underdiagnosed and undertreated in many flocks worldwide.

Key Facts

Footrot (Dichelobacter nodosus) and contagious ovine digital dermatitis (CODD) are the leading causes of sheep lameness in the UK
Lameness prevalence in UK flocks averages around 10%, meaning one in ten sheep is lame at any given time
Lame sheep show measurable pain responses including grimace scale changes, altered gait, and reduced grazing time
Studies show lame sheep lose condition at twice the rate of sound sheep, with significant impacts on reproduction and lamb survival
Footrot is treatable with appropriate antibiotics and foot bathing, but early intervention is critical for rapid recovery
The Five Point Plan for sheep lameness recommends: prompt treatment, culling of non-responders, vaccination, avoidance of wet conditions, and quarantining new stock
CODD is more difficult to treat than footrot and can cause complete hoof horn separation — an extremely painful condition
Farmers frequently underestimate lameness prevalence in their flocks and delay treatment, extending the period of suffering

Welfare Considerations

Sheep lameness is one of the highest-prevalence welfare problems in UK and global livestock farming. A lame sheep suffers continuously — every step, every movement to feed or water, every interaction with the flock involves pain. Yet lameness in sheep is frequently tolerated at levels that would be unacceptable in cattle or other species, partly because individual sheep are harder to monitor in large outdoor flocks and partly because clinical signs of pain are subtle in a prey species evolved to conceal vulnerability. The welfare case for rapid identification and treatment is overwhelming: lame sheep treated within 3 days recover in half the time of those treated after 7+ days, meaning every day of delay doubles the suffering period. Farmers who score flocks regularly — walking them through a race and observing gait on a 0–3 scale — detect lameness earlier and treat more promptly. The Five Point Plan provides a practical evidence-based framework that, when consistently implemented, can halve flock lameness prevalence. Achieving this across the industry would prevent millions of sheep-days of unnecessary pain each year.

What You Can Do

Support sheep welfare standards that require lameness scoring and maximum treatment delay times
Choose lamb and wool from farms participating in lameness reduction programmes
Advocate for veterinary-farmer partnerships focused on flock lameness monitoring and the Five Point Plan
Raise awareness that sheep lameness is a major welfare issue that is preventable and treatable
Support research into CODD treatment protocols, which are less well established than footrot management
Encourage sheep farmers to walk flocks regularly for lameness scoring rather than waiting for obvious signs
