Use of deslorelin acetate implants to control aggression in a multi-male group of Rock Hyrax (Procavia capensis)

Aggression among male animals can be difficult to manage in captive populations, and several strategies including separation, castration, and behavioral modification have been used with varying degrees of success. Many aggression issues are normal sequela from hormonal fluctuations occurring when an animal reaches sexual maturity or during the breeding season, and multi-male groups can be especially problematic as the individuals vie for dominance. In this case, aggression in an all-male group of Rock Hyrax (Procavia capensis) has been managed successfully with serial deslorelin implantation for the past 5 years.
