Lameness is one of the most prevalent and painful welfare problems in dairy and beef cattle, affecting millions of animals globally and representing both a welfare crisis and an economic burden.
Lameness in cattle is a chronic pain condition that profoundly impairs quality of life. Affected cows adopt weight-shifting postures, spend more time lying down, and show reduced social engagement — all indicators of significant discomfort. The gap between lameness prevalence and lameness treatment is a major welfare concern: studies consistently show that farmers underestimate lameness in their herds because cattle mask pain behavioural signs. Locomotion scoring — regular systematic observation of gait — is one of the most important tools for detecting lameness early enough to treat it effectively and humanely.
