Used in veterinary medicine as an antibacterial agent to treat bacterial infections in livestock and poultry. It belongs to the sulfonamide class and works by inhibiting bacterial growth, particularly effective against certain gram-positive and gram-negative bacteria. Commonly administered in feed or water to control outbreaks of diseases such as mastitis, respiratory infections, and enteric infections in animals. Its use is regulated due to concerns about residues in food products and development of antimicrobial resistance.
