Establishing treatment protocols for clinical mastitis.

Each farm has a unique mix of mastitis pathogens and management procedures that have evolved over time. The herd veterinarian should work with the manager/owner to systematically develop treatment protocols that meet the needs and management of the farm. To establish a mastitis treatment protocol, it is necessary to develop a system to routinely identify clinical mastitis cases, develop a herd-specific severity level assessment system, manage the clinical mastitis cases based on severity level and culture result (when available), avoid antibiotic residues, and monitor the success of the system and alter the protocol as necessary.
