Dairy Cow Mastitis Prevention and Pain Management

Mastitis is the most common and costly disease in dairy cattle globally, causing significant pain and suffering that is often inadequately treated due to economic constraints and cultural attitudes toward bovine pain.

Key Facts

Clinical mastitis affects 25-40% of dairy cows in most herds at least once per lactation
The infection causes pain, swelling, heat, and altered milk production in the affected quarter
Subclinical mastitis is even more prevalent and causes chronic low-grade inflammation without obvious signs
Anti-inflammatory pain relief is underused in mastitis treatment despite evidence of welfare and production benefit
Dry cow therapy using antibiotics at drying off prevents mastitis but raises antibiotic resistance concerns
Selective dry cow therapy based on individual cow infection status reduces antibiotic use without welfare cost
Milking hygiene, teat dipping, and udder health monitoring programs substantially reduce mastitis incidence

Welfare Considerations

Mastitis causes genuine pain that alters cow behavior, reduces feed intake, and impairs immune function. The underuse of pain relief in mastitis treatment reflects both economic constraints and persistent uncertainty among some farmers about whether cows experience pain in ways that warrant treatment. The scientific evidence strongly supports routine anti-inflammatory treatment as both a welfare improvement and a production benefit — cows treated for pain in mastitis recover faster and produce more milk. Closing the gap between evidence and practice through farmer education and policy requires framing mastitis pain management as both an ethical obligation and a commercially rational decision.

What You Can Do

Support dairy welfare standards requiring pain relief as part of mastitis treatment protocols
Advocate for anti-inflammatory use guidance to be included in dairy farm certification standards
Choose dairy products from farms with documented low mastitis prevalence and treatment protocols
Encourage veterinary practices to default to pain relief inclusion in mastitis treatment plans
Support research on mastitis prevention strategies that reduce disease burden and treatment need
