Dairy Mastitis Treatment: Welfare-Optimal Protocols

Mastitis—udder inflammation, usually caused by bacterial infection—is the most common disease in dairy cattle and one of the most significant sources of welfare harm in dairy farming globally. Welfare-optimal mastitis management requires prompt identification, appropriate treatment including pain relief, and robust prevention programs.

Mastitis Pain and Welfare

Mastitis is a painful inflammatory condition. Research confirms that cows with clinical mastitis show behavioral pain indicators: reduced lying time, altered gait, suppressed appetite, and elevated pain biomarkers. Subclinical mastitis—without visible signs—also causes measurable discomfort detectable through behavioral observation and somatic cell count monitoring. Pain management is a welfare requirement in mastitis treatment, not optional.

Treatment Protocols

Clinical mastitis: Treatment typically involves intramammary antibiotic tubes, systemic antibiotics for severe cases, and NSAIDs (meloxicam, ketoprofen) for pain relief and anti-inflammation. NSAID use improves welfare outcomes and also speeds recovery—making it both ethically and economically justified. Supportive care: Frequent stripping of the affected quarter removes toxins and inflammatory mediators. Oxytocin improves milk letdown in some cases. Severe cases: Peracute mastitis with systemic illness requires urgent veterinary attention and intensive supportive care.

When Not to Treat

Severe, chronic mastitis cases that fail to respond to treatment may require culling decisions. Delaying culling of chronically suffering cows to preserve production value represents a welfare failure. Clear treatment protocols with defined response checkpoints and culling criteria are welfare-essential.

Prevention

Post-milking teat dipping, dry cow therapy, milking hygiene, and teat condition monitoring all reduce new infection rates. Herd-level somatic cell count monitoring targets prevention before clinical disease develops.
