Musth — a periodic state of elevated testosterone and aggressive behavior in male elephants — creates significant welfare management challenges in both wild and captive contexts.
Musth welfare involves genuine welfare considerations for individual bull elephants alongside the safety and management challenges it creates. The physiological state includes facial gland secretion that stains the face, dribbling urine that soaks the back legs, and behavioral agitation that appears uncomfortable rather than simply aggressive — these are signs of a physiologically driven state that the bull cannot voluntarily moderate. Captive bulls in musth managed through complete isolation experience social deprivation that compounds the physiological discomfort of the state. Wild bulls in musth that come into conflict with human infrastructure face retaliatory killing that causes direct welfare harm. Non-lethal management including aversive deterrents, early warning systems, and spatial separation addresses safety without the welfare cost of lethal control, while captive management protocols using protected contact reduce keeper risk without requiring sustained isolation.
