According to the American Veterinary Medical Association, judicious therapeutic use of antimicrobials is a core principle of the broader goal of Antimicrobial stewardship. Antimicrobial stewardship involves maintaining animal health and welfare by implementing a variety of preventive and management strategies to prevent common diseases; using an evidence-based approach in making decisions to use antimicrobial drugs; and then using antimicrobials judiciously, sparingly, and with continual evaluation of the outcomes of therapy, respecting the client's available resources. In addition, other management and intervention strategies may be considered prior to antimicrobial therapy for infectious diseases.¹ 

The American Association of Bovine Practitioners has published guidelines for cattle practitioners that emphasize the need for a veterinarian to assist in management, immunization, housing and nutritional programs in addition to treating cattle. The AABP Judicious Therapeutic use of Antimicrobial in Cattle² also addresses selection of appropriate antibiotics, dose and duration of use, and training of farm personnel.  Tips for implementing these principles in beef and dairy practices can also be found on the AABP website.
