Widely used in veterinary medicine, this compound serves as an effective antibiotic for treating bacterial infections in livestock and companion animals. It is commonly administered to cattle, swine, and poultry to control respiratory diseases, mastitis, and enteric infections caused by susceptible microorganisms. Due to its potency against gram-positive bacteria and some gram-negative pathogens, it plays a key role in promoting animal health and productivity in agricultural settings. It is also used as a growth promoter in some feed formulations, enhancing weight gain and feed efficiency. In addition, it finds use in laboratory settings as a selective agent in cell culture and molecular biology, particularly in resistance marker systems for genetic engineering.
