Doxycycline (Atridox)

Doxycycline (Atridox) is a semisynthetic tetracycline antibiotic. It is one of the more effective drugs for treating Mycoplasmosis and Chlamydiosis. In order to be effective at treating infections, birds require prolonged treatment periods of 30 to 45 days.

Caution: Prolonged treatment can have catabolic and immunosuppressive effects, reduce normal gut flora, and increases the risk of opportunistic secondary infections. Birds with existing liver or kidney disease should be closely observed when given this medication.

Egg Withdrawal Period: Doxycycline is not approved for use in poultry producing eggs intended for human consumption in any country. However, multiple studies have been performed to evaluate the depletion of doxycycline in the eggs of treated hens. It is associated with a 7-day withdrawal period for chickens intended for meat purposes .
