Bovine Papillomatosis (Warts): Welfare and Management
Bovine papillomatosis causes wart-like growths on cattle skin, with welfare implications ranging from minor irritation to severe functional compromise.
Key Facts
- Caused by bovine papillomaviruses (BPV), highly contagious in young cattle
- Lesions commonly occur on the head, neck, and shoulders of young animals
- Most cases resolve spontaneously as immune responses develop
- Severe cases may cause difficulty eating, vision obstruction, or teat involvement
- Teat warts in dairy cows interfere with milking, causing pain and mastitis risk
Welfare Considerations
The welfare impact of bovine papillomatosis varies enormously with lesion location and extent. Most cases in young cattle are a temporary nuisance resolving without treatment. However, warts around the eyes causing vision problems, around the mouth interfering with feeding, or on teats of dairy cows causing pain during milking represent significant welfare problems. Teat warts in dairy cows are particularly important: pain during milking leads to behavioral indicators of distress and increases mastitis risk when milking is incomplete. Prompt identification and appropriate management of welfare-compromising lesion locations is essential.
What You Can Do
- Inspect young cattle regularly for wart development, particularly around the face and neck
- Prioritize teat wart treatment in dairy cows to prevent milking pain
- Implement good hygiene to reduce spread through shared equipment
- Consult your vet about autogenous vaccines for persistent herd problems
- Avoid traumatizing warts, which can spread infection and cause pain
