Cattle Digital Dermatitis: Farm-Wide Control Programs

Digital dermatitis is the most common cause of lameness in dairy cattle. Farm-wide footbathing and individual cow treatment programs reduce this painful condition effectively.

Key Facts

Digital dermatitis affects up to 25% of dairy cows on infected farms without control programs
The condition causes painful ulcerative lesions on the skin above the hoof
Treponema bacteria in wet, contaminated walkways spread the disease between cows
Copper sulfate or formalin footbaths reduce new infection rates by 70 to 80%
Individual lesion treatment with oxytetracycline spray achieves rapid healing in early stages

Welfare Considerations

Digital dermatitis causes intense pain with every step, manifesting as cows lifting affected feet, reluctance to walk, and reduced feed intake. A single lesion on one cow can spread rapidly through the standing herd via contaminated walkways. Control requires addressing both individual affected cows and the farm environment that allows spread. Footbathing programs protect healthy cows while early lesion treatment prevents progression to chronic, hard-to-treat stages. Farms with comprehensive digital dermatitis programs show dramatically lower lameness prevalence and corresponding welfare improvements.

What You Can Do

Implement twice-weekly copper sulfate or formalin footbathing on dairy units with digital dermatitis
Train stockpeople to identify and treat lesions at the earliest, most treatable stage
Score all cows for digital dermatitis at routine foot trimming and track prevalence over time
Clean and maintain walkways to reduce the wet, contaminated conditions that spread bacteria
Work with your vet and foot trimmer to develop a farm-specific digital dermatitis control plan
