Lameness is one of the most prevalent welfare problems in dairy and beef cattle. Early detection and treatment dramatically reduces suffering and improves outcomes.
Lameness causes chronic pain that affects every aspect of a dairy cow's life. Lame cows lie down less (preferring to stand despite discomfort to avoid painful getting up), eat less, lose body condition, and show suppressed social behavior. The welfare significance is amplified by the scale - with 25-30% prevalence, the majority of dairy herds have substantial numbers of lame animals at any time. The welfare leverage point is early detection: automated mobility scoring systems and trained stockperson observation can identify lameness before it becomes severe, enabling rapid treatment that prevents weeks of painful suffering that established lameness causes.
