Evaluation of Pronghorn (Antilocapra americana) Chemical Immobilization in a Captive Research Facility in Wyoming, USA (2021-24).

A retrospective case study evaluated the effectiveness of butorphanol (27.3 mg/mL), azaperone (9.1 mg/mL), and medetomidine (10.9 mg/mL; BAM) in captive pronghorn (Antilocapra americana) during 2021-24. Immobilizations were inconsistent, with documented cases of spontaneous arousal (e.g., head movement, walking, running). Use of BAM in pronghorn should be considered with caution.
