A new study suggests this and ulcers may be caused by SWS (small willy syndrome). Which has something to do with low self-esteem caused by caretakers not grouping turnout and stall mates according to size.
The study was small in size and scope and was done by the supplement manufacture. It also advised in addition to feeding their product the horse should undergo extensive one on one therapy/counseling sessions with one of their specialist.
