Drug Type: Antibiotic


Marbofloxacin is fluoroquinolone antibiotic with a similar bactericidal spectrum to enrofloxacin (Baytril). Marbofloxacin has good oral bioavailability in ducks (72 to 88%).

In the United States, since this drug is a fluoroquinolone-class antibiotic, it is not approved for use in poultry that are not kept as pets. It is available by prescription only, meaning that you will need to obtain it through your veterinarian who will prescribe it "extra-label" to poultry kept as pets.

Caution: Marbofloxacin should be avoided in very young birds, as it can cause damage to joint cartilage. It should be used with extreme caution in animals with pre-existing disorders of the brain or spinal cord.
  • For chickens and ducks, 2-2.5 mg/kg PO q24h
  • For turkeys, 3-12 mg/kg PO q24h
