Mastitis effects farmers financially in many ways, not only through the cost of mastitis treatments and veterinary costs, but also other indirect costs such as discarded milk, reduced milk yield and quality, fertility problems, higher replacement costs, loss of genetic potential and extra labour requirements. The average cost of one clinical case of mastitis is considered to be around £211*. With the average incidence of clinical mastitis in the UK in 1999 being around 45 cases per 100 cows a year, that's £9,495.
