Training captive chimpanzees to cooperate for an anesthetic injection

Abstract

Captive animals trained to cooperate with routine medical procedures, such as injections, may experience less aggression and anxiety than those forced to comply through the use of restraints. The authors used positive reinforcement training to teach captive chimpanzees to present a body part for anesthetic injection and determined the time investment necessary for initial training and duration of maintenance of the behavior after completion of the training.
