Abstract: | The clinical effectiveness of tiletamine/zolazepam with and without xylazine and of carfentanil with xylazine for the immobilization of gaur (Bos gaurus) was compared. Six animals were immobilized with tiletamine combined in a 1:1 ratio with zolazepam at an average total dose of 4.0 mg/kg (range, 3.0-4.7 mg/kg). Six animals were immobilized with tiletamine/zolazepam at an average total dose of 4.6 mg/kg (range, 2.7-6.7 mg/kg) plus xylazine at an average total dose of 0.13 mg/kg (range, 0.04-0.23 mg/kg). Six animals were immobilized with carfentanil at an average total dose of 7.6 μg/kg (range, 5.0-10.0 μg/kg) combined with xylazine at an average dose of 0.10 mg/kg (range, 0.08-0.13 mg/kg). Difficulties were encountered with induction and maintenance of immobilization with tiletamine/zolazepam both with and without xylazine. No statistically significant differences among treatment groups were found in the initially recorded heart rate, respiratory rate, or rectal temperature. Blood pressure was lower in animals that received tiletamine/zolazepam with xylazine than in those that received tiletamine/zolazepam alone. Doxapram, given to five animals immobilized with tiletamine/zolazepam or tiletamine/zolazepam--xylazine, did not shorten recovery time when given at an average dose of 0.5 mg/kg i.v. Recovery was rapid in all carfentanil--xylazine-immobilized animals when reversed with naloxone or naltrexone both with and without the alpha-2 antagonist yohimbine. Renarcotization 12-24 hr after initial recovery was observed in two of six animals immobilized with carefentanil--xylazine. Carfentanil--xylazine was the most useful combination, considering the low dose volume, reversibility, and rapid induction and recovery with this regimen, although further investigation of the renarcotization problem is needed. |
