Lameness is one of the most prevalent and painful welfare conditions in dairy and beef cattle, and one where prevention and early treatment can dramatically reduce suffering.
Dairy cow lameness is both a welfare crisis and a welfare opportunity: it is highly prevalent, causes significant pain, and is substantially preventable through evidence-based management. A lame dairy cow experiences chronic musculoskeletal pain that impairs her ability to compete for feed, access lying areas, and engage in normal social behavior — compounding the primary pain with secondary nutritional and social welfare harms. The progression from early lameness (detectable only with careful locomotion scoring) to severe lameness (obviously visible) represents weeks of untreated pain during which each day of delay worsens the prognosis. Regular locomotion scoring that identifies early lame animals, combined with prompt treatment and management of risk factors, is the established welfare solution. The economic alignment — lame cows cost producers substantially more than prevention costs — should make lameness control a priority in every dairy herd.
