Measurement of tetracycline levels in parakeets.
Parakeets were fed hulled millet seed containing 0.5% chlortetracycline (CTC) or minocycline. Blood concentrations of more than 1 micrograms CTC/ml and more than 5 micrograms minocycline/ml were obtained. Equivalent drug assay results were obtained from blood specimens collected by venipuncture or by use of treated filter-paper discs. The latter is a fairly simple method for assaying CTC concentrations in blood of treated psittacines.
