     Aggression that results in wounding concerns all managers of captive chimpanzee facilities and with recommendations for larger, complex social groups it will remain a concern into the future. Subjects were 173 chimpanzees (89 F, 84 M, age range 0-54, mean= 30.4, average group size = 7.67) housed at Chimp Haven, Inc. Location and severity of the wound, as well as any veterinary intervention were recorded. Wounds that required no veterinary intervention were categorized as minor. Those that required painkillers, antibiotics, topical treatment, sutures, amputation, or sedation were considered major. Wounding rates were used for analysis as our population changes regularly due to incoming chimpanzees, deaths, and introductions. Between January 1, 2007 and July 10, 2012, 837 wounds were recorded (90.08% minor, 9.92% major; mean wounding rate = 1.36 per year). Males received more wounds (1.77) than females (.97)(t = 1.99, p < 0.05) overall and in both the major and minor categories (t = 1.87, p < 0.05minor; t = 1.96, p < 0.05major). Adolescent chimpanzees (10-13) had the highest rate of wounding (1.53) followed closely by adults 14-44 (1.41). Older chimpanzees (44+) had reduced wounding rates (1.04). This study found no differences in rates of wounding between age-sex categories. It will be important to monitor any variation in wounding rates as additional chimpanzees are retired and larger groups are formed.
