Lameness affects an estimated 20-30 percent of UK dairy cows at any one time, making it the most prevalent welfare problem in the dairy industry and a major source of chronic pain.
Lameness causes chronic severe welfare suffering — a lame cow walks reluctantly, lies down more frequently, is displaced from feed and water by dominant cows, loses body condition, and experiences pain with every step. Studies using behavioural and physiological indicators confirm that lame cows experience significant pain. The tragedy of dairy cow lameness is that it is largely preventable through a combination of regular preventive foot trimming, adequate lying time in well-bedded cubicles, good nutritional management, and prompt treatment when early lesions are detected. Farms with lameness prevalence below 10 percent demonstrate that high welfare and high production are not incompatible. The gap between best-practice and average performance represents an enormous avoidable welfare burden.
