Widely used in veterinary medicine, especially in livestock and poultry, to treat bacterial infections caused by Gram-positive bacteria and some Gram-negative organisms. Commonly added to animal feed or administered in drinking water for the control of respiratory diseases, such as bovine respiratory disease and swine dyspnea. Also effective against mycoplasma infections in chickens and turkeys, helping improve growth performance and feed efficiency. Frequently used in aquaculture to manage bacterial diseases in fish. Due to its antimicrobial activity, it plays a role in reducing disease outbreaks in intensive farming systems. Not approved for use in humans due to potential toxicity and risk of antibiotic resistance development.
