Doxycycline plasma concentrations in macaws fed a medicate corn diet.
A trial was conducted to determine the doxycycline plasma concentrations attained by feeding a medicated corn diet to large psittacine birds. Doxycycline is the preferred drug for the treatment of chlamydiosis in psittacine birds. Healthy macaws were fed a 0.1% doxycycline-medicated corn diet for 45 days, and plasma doxycycline concentrations were determined by microbiological assay on treatment days 3, 15, 30, and 45. Plasma doxycycline concentrations exceeded 1 microgram/ml in 87% of the samples assayed. As blood concentrations of 1 microgram/ml are considered therapeutic, a doxycycline-medicated corn diet may be efficacious in the treatment of chlamydiosis in large psittacine birds.
