Chemical Immobilization Of Red Foxes (Vulpes Vulpes), Terry J. Kreeger, Ulysses S. Seal, John R. Tester

Other Publications in Zoonotics and Wildlife Disease

Red foxes (Vulpes vulpes) were immobilized with one of the following drug combinations: ketamine/xylazine (n = 22), ketamine/ promazine (n = 35), ketamine/midazolam (n = 13), or tiletamine/zolazepam (n = 22). Foxes given ketamine/xylazine had the shortest induction and longest recovery times relative to other drug combinations, whereas foxes given ketamine/midazolam had the longest induction times. Recommended doses for the various combinations are given. Foxes given ketamine/xylazine were given either 0.1, 0.2, 0.4 mg/kg yohimbine, or saline 40 mm after anesthetic induction. Administration of yohimbine significantly shortened arousal and recovery times relative to control values (P < 0.001).
