Dairy Cow Mastitis Welfare: Scale and Prevention

Mastitis is the most costly and common disease in dairy cows, causing significant pain and welfare harm to millions of cows annually worldwide.

Key Facts

Mastitis affects around 25-40% of cows annually in most UK dairy herds
Clinical mastitis causes swollen, painful udders with acute systemic illness in severe cases
Subclinical mastitis causes no visible signs but reduces milk quality and causes chronic discomfort
Antibiotic treatment is required for clinical mastitis raising antibiotic resistance concerns
Prevention through teat dipping, dry cow therapy, and management reduces incidence significantly

Welfare Considerations

Dairy cows with clinical mastitis experience acute pain from inflamed udder tissue, fever, and systemic illness that reduces feed intake and social behaviour. Severe E. coli mastitis causing septicaemia is extremely painful and rapidly fatal without prompt treatment. Chronic subclinical mastitis, while less acutely painful, causes ongoing discomfort during milking and chronic immune activation. The scale of mastitis in dairy herds means millions of cows globally experience udder pain each year, making it one of the most significant farm animal welfare problems by total suffering burden.
