Florfenicol is a broad-spectrum, primarily bacteriostatic antibiotic with a similar mechanism of action as chloramphenicol (inhibition of protein synthesis).
Florfenicol is effective against a number of many Gram-negative and Gram-positive organisms, including certain chloramphenicol-resistant strains of
Escherichia coli, Salmonella typhimurium and
Staphylococcus aureus. Florfenicol is used most often to treat respiratory diseases.
Florfenicol is effective for the control of
Riemerella anatipestifer in ducks, especially if used in combination with
doxycline (Li, Fa-Lei, et al. 2025).
Caution: Recent research shows that florfenicol causes kidney damage to broilers and is toxic to developing chick embryos at around day 5 of incubation.
