Do all performance horses have ulcers?
Various studies have reported the incidence of ulcers in performance horses to range from 40-60% in sport horses such as dressage, show jumping (McClure et al. 1999, Mitchell 2001), endurance (Nieto et al. 2004), and western performance (Bertone, 2000) while the incidence in race horses is reported to be as high as 80-90% (Murray, 1996-2000 and Vatistas, 1999).
