Ten ferrets were used in a crossover study to determine the sedative effects of intramuscularly (IM) administered diazepam (3 mg/kg body weight)-butorphanol (0.2 mg/kg body weight), acepromazine (0.1 mg/kg body weight)-butorphanol (0.2 mg/kg body weight), or xylazine (2.0 mg/kg body weight)-butorphanol (0.2 mg/kg body weight). All ferrets became laterally recumbent following the administration of each drug combination. The xylazine-butorphanol combination caused a significantly longer (p less than 0.05) duration of analgesia than the diazepam-butorphanol and acepromazine-butorphanol combinations. None of the ferrets could be intubated with any of the drug combinations. The time from induction to recovery was significantly shorter in the acepromazine-butorphanol-treated ferrets. A significantly lower heart rate was observed in the xylazine-butorphanol-treated ferrets; however, an acceptable systolic blood pressure was maintained. Ventilatory function was more depressed in the diazepam-butorphanol- and xylazine-butorphanol-treated ferrets than in the acepromazine-butorphanol-treated ferrets. Xylazine-butorphanol was found to be the best combination for use in ferrets.
