Used primarily in veterinary medicine as a broad-spectrum antibacterial agent, especially in the treatment of respiratory, gastrointestinal, and urinary tract infections in livestock such as cattle, swine, and poultry. It is effective against a range of Gram-positive and Gram-negative bacteria. Commonly administered through feed or drinking water, it is often used for the prevention and control of coccidiosis and bacterial complications in intensive farming. Its long-acting properties allow for less frequent dosing, making it suitable for mass medication in large herds or flocks. Also used in some cases for prophylaxis during periods of stress or high disease risk.
