Digital dermatitis is the most prevalent infectious foot disease in dairy cattle globally, causing significant lameness and pain.
Digital dermatitis causes acute and chronic pain. Active lesions with exposed tissue cause intense local pain visible through the cow's reluctance to weight-bear. The high prevalence across dairy herds means this is a significant population-level welfare problem. Systematic footbathing, early treatment, and biosecurity to prevent herd introduction provide both individual and population welfare benefits.
