title: Blood concentrations of chlortetracycline in macaws fed medicated pelleted feed.
abstract: A trial was conducted to determine the suitability of using a pelleted diet containing chlortetracycline (CTC) for treatment of chlamydiosis in macaws. Macaws, normally fed seed and fruit diets in captivity, are notoriously difficult to treat with CTC-medicated mash diets. Healthy macaws fed a pelleted diet containing 1% or 1.5% CTC for 30 or 45 days maintained adequate food intake and mean blood concentrations of 1-2 CTC micrograms/ml blood throughout the treatment period. There were no significant differences between blood concentrations induced by the different dietary CTC concentrations. Blood concentrations of 1 microgram/ml are considered therapeutic, so it is likely that 1% CTC-medicated pellets will be adequate for treating chlamydiosis in these species.
