Used primarily in veterinary medicine, this compound serves as a feed additive to promote growth and improve feed efficiency in livestock such as poultry, swine, and cattle. It is effective in preventing and controlling bacterial infections, particularly those caused by susceptible strains of Gram-positive and Gram-negative organisms. Due to its broad-spectrum antimicrobial activity, it is commonly included in animal feed for the prophylaxis of respiratory, gastrointestinal, and other systemic infections. Its anhydro form offers improved stability in feed formulations under various storage and processing conditions. Not approved for use in animals producing milk for human consumption due to residue concerns.
