The control of bovine mastitis is the biggest challenge the large animal practitioner is faced with today. When combined with reproductive disease control, it is a valuable service to the dairyman and a good source of income for the veterinarian. In most areas of the country, there is a real demand for preventive veterinary medicine. Probably, a group or partnership practice with specialists programmed for periodic visits to the dairy farm is the best approach to mastitis and reproductive disease control.
