The Metabolism of P32-Labeled Ciodrin in a Lactating Goat

Abstract

A study was made of the metabolism of P³²-labeled Ciodrin®, alpha-methylbenzyl 3-bydroxycrotonate dimethl phosphate, by a dermally treated milk goat. Eleven percent of the applied dose was eliminated in the urine. Only minute quantities of radioactive material appeared in the feces and milk. Dimethl phosphoric acid accounted for 79.7 to 91.2% of the radioactive material in the urine. No radioactive material could be extracted from the blood, and the maximum true residue in the milk was only 0.20 ppb.
