Immobilization of mountain goats with xylazine and reversal with idazoxan

Mountain goats (Oreamnos americanus) were captured in traps and immobilized with xylazine, later reversed with idazoxan. One hundred and forty-one goats were immobilized, 94 with a single injection and 47 with multiple injections. Dosage (mg/kg of body weight) of xylazine received, induction time, and recovery time after handling did not differ among sex-age classes. Increasing the dosage did not shorten induction time. The first injection of xylazine in multiple-injection captures was lower than the dose given in single-injection captures, suggesting that insufficient initial doses of xylazine made multiple injections necessary. Xylazine is an effective drug for immobilization of mountain goats captured in traps, at dosages of about 4.9 mg/kg. The dosage of xylazine required to immobilize mountain goats is higher than that reported for bighorn sheep and white-tailed deer.
