Mastitis is the most common and costly disease in dairy farming, causing pain to millions of cows and representing a major welfare challenge.
Mastitis causes localized udder pain, systemic fever, lethargy, and reduced milk production. Chronic subclinical mastitis may persist for months causing ongoing discomfort without obvious clinical signs. Intensive milking schedules and high milk production genetics increase mastitis risk. Prevention through management, milking hygiene, and vaccination is more effective and humane than relying on antibiotic treatment.
