DECOQUINATE .2. ABSORPTION AND RESIDUE STUDIES IN CHICKENS

Decoquinate has been determined in edible chicken tissues by a spectrophotofluorimetric method during and after medication with 0.004% of the compound in the feed for five weeks. Mean concentrations (ppm fresh weight) of decoquinate observed during treatment were 1.1 (liver), 0.8 (kidney), 0.2 (muscle), 0.1 (blood), 1.6 (fat) and 1.0 (skin). Similar results were obtained with nine weeks' medication at 0.003 % and eight weeks at 0.008 %. Decoquinate was eliminated rapidly when medication ceased and all tissues contained < 0.1 p pm three‐four days later. Copyright © 1969 John Wiley & Sons, Ltd
