Ciprofloxacin (Baytril, Enrotril) is a fluroquinolone, broad-spectrum antibiotic which is useful for treating a wide range of bacterial infections in poultry---both Gram-positive and Gram-negative bacterial organisms. Baytril is the veterinary-labeled form of ciprofloxacin. Fluroquinolone antibiotics are the drug of choice against Mycoplasma
species, and most gram-negative bacteria, which includes Escherichia coli
, and Salmonella
; they aren't as effective against gram-positive bacteria.
Baytril is available in tablet form, as an injection and as an oral syrup. 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.
Poultry taking this medication should be concurrently monitored for signs of secondary infections, especially those caused by yeast (sour crop
). Treating young, growing birds with Baytril may cause permanent damage to their joints. Baytril can interfere with cartilage deposition on the surface of the joints which may lead to permanent deformity.
Treating birds with fungal infections with Baytril will make the infection worse.
Egg Withdrawal Period:
Ciprofloxacin should not be used in female poultry producing eggs intended for human consumption. The drug does not have a maximum residue limit for eggs.
10-30 mg/kg given twice daily, by mouth, usually for 3-5 consecutive days. The later (5 days), is usually indicated for birds with mixed infections and/or chronic progressive forms of infection. If there are no signs of improvement within the first 2-3 days, an alternate antibiotic should be considered and selected based on susceptibility testing.
Ciprofloxacin can remain physically and chemically stable over a 48 month storage period. However, once opened, the drug should be discarded after 12 weeks. If diluted in water, it should be discarded after 24 hours.
