Digital dermatitis is the most prevalent infectious cause of lameness in dairy cattle worldwide, causing significant pain and welfare harm that is preventable through systematic herd management.
Digital dermatitis causes chronic, debilitating pain that fundamentally impairs cattle welfare. Lame cows alter their weight distribution, spend less time standing at the feed face, and reduce social interactions — all measurable welfare impacts. Pain assessment using validated tools confirms that active digital dermatitis lesions are significantly painful, equivalent to moderate-to-severe pain in validated animal pain scales. The welfare harm is compounded by the fact that lame cows are often not identified promptly: in large herds, individual gait assessment is infrequent, and subclinically lame cows may endure weeks of pain before detection. The disease is highly contagious and spreads through contaminated wet environments — housing and slurry management are therefore central to prevention. Regular locomotion scoring (minimum fortnightly), prompt treatment of identified cases, and consistent footbath use represent the evidence-based management triad for reducing digital dermatitis welfare burden.
