Pain Management in Cattle: Evidence & Practice

Pain Management and Cattle Welfare

For much of the 20th century, pain in cattle was significantly underestimated and undertreated. Modern welfare science has established that cattle have nociceptors, pain processing pathways, and demonstrate clear behavioural and physiological responses to pain. Appropriate pain management is both an ethical obligation and a clinical imperative in modern cattle practice.

The Science of Bovine Pain

• Cattle have been shown to respond to noxious stimuli with elevated cortisol, altered gait, changes in feeding behaviour, and reduced production
• Validated pain assessment tools (Bovine Pain Scale, Cattle Pain Scale) provide standardised measurement of pain severity
• Untreated pain impairs immune function, delays healing, and reduces welfare outcomes even in successfully treated disease
• Pain causes suffering — a welfare harm independent of its impact on production

NSAIDs in Cattle Practice

• Meloxicam: Most studied bovine NSAID; strong evidence for welfare benefit in calf pain (dehorning, castration, respiratory disease), mastitis, and lameness
• Ketoprofen: Licensed for cattle; effective anti-inflammatory and analgesic
• Flunixin meglumine: Particularly effective for visceral pain and endotoxaemia (grain overload, mastitis-related pain)
• Carprofen: Used in some markets with evidence for lameness and post-surgical pain

Local Anaesthesia

• Lidocaine for routine procedures: cornual nerve block (dehorning), ring block (castration), epidural (obstetric procedures)
• Required by UK law for disbudding/dehorning without anaesthesia over a specified age
• Insufficient alone for prolonged pain relief — must be combined with NSAIDs for extended procedures

Conditions Requiring Proactive Analgesia

• Lameness (particularly digital dermatitis, white line disease, sole ulcer)
• Clinical mastitis — significantly underanalgesed in practice despite clear welfare evidence
• Surgical procedures (caesarean section, digit amputation, abomasopexy)
• Dystocia (difficult calving) and post-partum complications
• BRD — fever and pleuritis cause significant pain alongside respiratory signs
• Dehorning, castration, disbudding (legal requirement in many jurisdictions)

Key Takeaways

Pain management in cattle has improved significantly but remains inconsistent in practice. Every veterinarian and farmer should understand that cattle experience pain, that validated tools exist to assess it, and that effective, affordable analgesics are available. Routine provision of NSAIDs alongside antibiotics for painful conditions is not optional welfare — it is standard of care.
