===Housing and Transport===

Housing in '''stables''' has been proposed as a risk factor for gastric ulcers, with more lesions being found in confined horses compared to those out at grass.(Murray and Eichorn1996).(Jonssen 2006).  However, when comparing solitary stable confinement with stabling next to a companion, and finally turn out in a paddock, Husted ''et al.'' found that the environmental situation had no effect on mucosal acid exposure in the equine stomach.<ref>Husted, L, Sanchex, L.C, Olsen, S.N, Baptiste, K.E, Merritt, A.M (2008) Effect of paddock vs. stall housing on 24 hour gastric pH within the proximal and ventral equine stomach.  ''Equine Vet J'', 40(4):337-41.</ref>  '''Transport''' has also been shown to induce squamous mucosal ulceration in horses.(71 in Sanchez)
