Used in veterinary medicine as an antimicrobial agent, particularly effective against respiratory pathogens in cattle, swine, and poultry. Commonly administered to treat bacterial infections such as bovine respiratory disease, swine dyspnea, and chronic respiratory disease in chickens. Its formulation allows for prolonged activity, supporting single-dose treatment protocols in some cases. Also used as a growth promoter in certain livestock operations to improve feed efficiency and weight gain. Effective against gram-positive bacteria and some gram-negative organisms, it is often chosen when animals are resistant to other macrolides.
