Mastitis Prevention in Dairy Cows: A Welfare Priority

Mastitis is the most common and costly disease in dairy cattle, causing significant pain and distress. Systematic prevention programs protect individual cow welfare and herd health.

Key Facts

Clinical mastitis affects approximately 30% of dairy cows each year in UK herds
The condition causes udder inflammation, fever, pain, and reduced milk production
Subclinical mastitis without clinical signs causes chronic welfare compromise in affected quarters
Teat dipping after milking reduces new infection rates by up to 50%
Dry cow therapy at the end of lactation treats existing infections and prevents new ones

Welfare Considerations

A cow with clinical mastitis is in significant pain - the inflamed quarter is hot, swollen, and exquisitely tender. She may stop eating, develop fever, and in severe cases show signs of systemic toxemia. Behind these clinical cases is a much larger burden of subclinical mastitis causing chronic, lower-grade inflammation and production loss without obvious symptoms. Systematic prevention - teat dipping, dry cow therapy, milking machine maintenance, hygiene protocols, and culling of chronically infected cows - dramatically reduces both the prevalence and severity of mastitis across dairy herds.

What You Can Do

Ensure post-milking teat dipping is implemented consistently on all dairy units
Work with a vet to review dry cow therapy protocols and adopt selective approaches where appropriate
Monitor somatic cell counts monthly as an indicator of mastitis prevalence in the herd
Prioritize milking machine testing and maintenance as part of mastitis prevention
Implement cow identification and treatment recording systems to track individual cow mastitis history
