Used as an antibacterial agent in veterinary medicine, particularly for treating bacterial infections in livestock and poultry. It is effective against a range of gram-positive and some gram-negative bacteria. Commonly administered in drinking water or feed to control outbreaks of diseases such as mastitis, metritis, and respiratory infections in cattle and swine. Also used in aquaculture to manage bacterial infections in fish. Its sodium salt form improves solubility, allowing for easier administration and faster absorption in animals.
