     Previous research suggests that positive reinforcement training (PRT) helps alleviate stress during potentially distressing events, such as anesthesia for physical examination, as indicated by changes in certain hematology values including white blood cell (WBC) counts, neutrophils (NEU), and glucose (GLU) levels. We consider the effects of PRT by comparing hematology levels of chimpanzees that were trained for voluntary IM injection versus untrained chimpanzees. One group of trained subjects had previous PRT experience (Exp; n=35, 14F, 21M; 3.5-15.17 yrs; mean=8.33) while another group of trained subjects were naïve to PRT (Naïve; n=11, 11F; 12.67-26.83 yrs; mean=18.71) prior to voluntary IM injection training. The third group of subjects remained untrained (Unt; n=27, 10F, 17M; 3.33-19.08 yrs; mean=14.22). Data were obtained from two annual physical examinations for each subject. For trained subjects one, data point was collected prior to onset of voluntary injection training and one after reaching training criteria. Among trained subjects WBC and NEU levels were significantly lower (WBC and NEU: Exp<Unt, p<.05; NEU: Naïve<Unt, p<.05), while GLU (Naïve>Unt, p<.05; Exp<Naïve, p<.05) was significantly higher. No effect of cooperation with injection was observed suggesting that PRT for voluntary injection lowers the stress responses of chimpanzees to sedation procedures, whether or not the subjects voluntarily present for injection. Additionally, continued participation in PRT for voluntary injection may result in increased cooperation with injection during subsequent sedation procedures.
