Dairy Cattle Lameness Scoring: Mobility Assessment and Welfare (2026)

Lameness is the most painful and economically important welfare problem in dairy cattle, affecting 20-30% of cows in many UK herds — systematic mobility scoring is the foundation of effective welfare improvement.

Key Facts

Approximately 25% of UK dairy cows are lame at any given time in unmanaged herds
Lameness causes chronic pain scoring equivalent to moderate-to-severe human pain conditions
Digital dermatitis (Mortellaro disease) is the most prevalent infectious foot condition on UK dairy farms
AHDB recommends monthly mobility scoring to identify lame cows for prompt treatment

Welfare Considerations

Lame cows experience persistent pain that impairs their ability to walk to feed and water, access lying areas, and engage in normal social behaviour. Pain assessment studies show lame cows have significantly altered behaviour including reduced time standing, altered lying patterns, and facial pain indicators. Digital dermatitis causes progressive, painful ulceration that worsens without treatment. Herd-level lameness rates above 5% indicate systemic welfare failure requiring structural intervention, not just individual cow treatment. Mobility scoring consistently applied enables early identification before lameness becomes severe.

What You Can Do

Implement monthly mobility scoring using AHDB or NMR mobility score systems
Treat lame cows within 2 days of identification with appropriate foot trimming and topical or systemic therapy
Address root causes: cubicle comfort, track surface, nutrition, and standing time as lameness risk factors
Set a target of less than 5% lame cows in your herd as a welfare and productivity goal
