Evaluation of A Combination of Ketamine and Dexmedetomidine as A Field Anesethetic Protocol for Immobilization of Golden-Mantled Howler Monkeys (Alouatta palliata palliata).

Background: The golden-mantled howler monkey (Alouatta palliata palliata) is an endangered primate experiencing acute population declines for reasons not fully identified. Health and disease monitoring are critical factors for understanding animal and ecosystem health, yet limited research has been achieved in this species due to difficulties in successful immobilization and sample collection. The purpose of this research is to investigate the efficacy of combined ketamine and dexmedetomidine in providing safe field anesthesia for golden-mantled howler monkeys (A.
