Florfenicol is widely used in veterinary medicine as an antibiotic to treat bacterial infections in livestock, poultry, and fish. It is particularly effective against respiratory and systemic infections caused by susceptible bacteria, such as Pasteurella, Actinobacillus, and Streptococcus species. In aquaculture, it is administered to control diseases like enteric septicemia in catfish and furunculosis in salmon. Florfenicol is also utilized in cattle and swine to manage conditions like bovine respiratory disease and swine pneumonia. Its broad-spectrum activity and ability to penetrate tissues make it a valuable tool in ensuring animal health and productivity.
