Used as a veterinary antibiotic to treat bacterial infections in livestock, particularly in swine and poultry. It belongs to the sulfonamide class and is effective against a broad spectrum of gram-positive and gram-negative bacteria. Commonly administered in feed or drinking water to control outbreaks of diseases such as respiratory infections, urinary tract infections, and enteric infections. Also used for prophylaxis during periods of stress or high disease risk. Its sodium salt form enhances solubility, allowing for easier administration in water-based systems. Due to concerns about antibiotic residues and resistance, its use is regulated in many countries, with withdrawal periods required before animal slaughter.
