Immobilizing Captive White-tailed Deer Using Medetomidine-Ketamine versus Xylazine-Telazol

Chemical immobilization often is the most effective method for capturing white-tailed deer (Odocoileus virginianus). Numerous chemical immobilization agents are available. We compared the efficacy and physiological effects of 2 white-tailed deer immobilizing agents: medetomidine-ketamine (M-K) antagonized with atipamezole, and xylazine-Telazol (X-T) antagonized with tolazoline. Mean induction time was longer and more variable for M-K. Mean reversal time and total down time was longer and more variable for X-T. Mean blood oxygen saturation (SpO2) in subjects treated with M-K was lower...
