Doxycycline is a semi-synthetic tetracycline antibiotic. It is one of the more effective drugs for treatment of diseases caused by Mycoplasma
spp. and Chlamydophila
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.
: Doxycycline hyclate tablets and capsules should be stored in tight, light resistant containers at temperatures less than 30°C, and preferably at room temperature (15-30°C). After reconstituting with water, the monohydrate oral suspension is stable for 14 days when stored at room temperature.
