Enrofloxacin (Baytril) is a fluroquinolone, broad-spectrum antibiotic which is useful for treating a wide range of bacterial infections. Baytril is the veterinary-labeled form of ciprofloxacin, which is the equivalent drug used for humans. In the United States, Enrofloxacin 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. Since this drug is a fluoroquinolone-class antibiotic, it is not approved for use in poultry that are not kept as pets. Fluroquinolone antibiotics are the drug of choice against Mycoplasma and most gram-negative bacteria, including:

Escherichia coli Enterobacter spp Klebsiella spp Pasteurella spp Proteus spp Salmonella Psudomonas aeruginosa (variably susceptible) And some gram-positive bacteria: Staphylococcus aureus Staphylococcus intermedius The oral syrup can be given directly to the mouth or dissolved in the drinking water. Due to its bitter taste, it may be necessary to mix the drug with another medium such as apple sauce or fruit juice to improve the taste. The drug is less effective when administered in drinking water. Caution: May cause muscle necrosis and pain at the injection site if given IM. Repeated IM injections are not recommended. Birds taking this medication should be concurrently monitored for signs of secondary infections and sour crop.


Baytril is a broad spectrum antimicrobial antibiotic that is effective against primary and secondary bacterial and mycoplasma pathogens associated with chronic respiratory disease in chickens and turkeys. Baytril is not licensed for use in hens producing eggs for human consumption.

You can only buy Baytril on prescription from your veterinary surgeon who may decide in the absence of any other licensed products to prescribe it. If this is the case, you will need to follow their advice for egg withdrawal periods. Be warned, some respected poultry vets are now advising that you should never eat the eggs from hens treated with Baytril because of the problem of antibiotic resistance in humans. It is usually very effective at clearing up respiratory infection in chickens that can be caused by diseases such as Mycoplasma Gallisepticum.

Antibiotic use:

 Antibiotics kill bacteria that are responsible for the infection although some bacteria survive treatment and go on to create more resistant strains of bacteria. If we get food poisoning, the antibiotics a doctor uses may not work if the bacteria is resistant. In addition to this, antibiotics also kill many of the naturally occurring ‘good’ bacteria that live in the gut. Antibiotics should only be considered as a last resort and always in consultation with your vet.

Dosage & Administration

The product is administered via the drinking water. Medicated water should be made up immediately prior to provision. Medication of the water supply should be continuous during the treatment period and no other source of water should be available. The product should be given over a minimum period of 6 hours per day to allow all birds to drink.

Poultry and Turkeys: The dose rate is 10 mg/kg body weight daily for 3 to 10 days. Each ml contains 100 mg enrofloxacin.

Calculate the daily quantity (ml) of Baytril 10% Oral Solution required for treatment period as follows:

Total number of birds x Average body weight in kg x 0.1 = Total volume (ml) per day

Baytril may be put directly into the header tank or introduced via a water proportioner pump. For the treatment of salmonellosis or pasteurellosis a treatment period of 5 to 10 days must be used. For other conditions the duration of treatment may be 3 to 5 days.
