Horses have evolved to naturally eat a mixed forage based diet (Thorne et al., 2005). Domestication has lead to restricted access to pasture and controlled monotonous diets unnatural to the horse, which may lead to Equine Gastric Ulcer Syndrome or Exertional Rhabdomyolysis (Azorturia), as well as behavioural ramifications. The discovery of a highly preferred forage type, more natural to the horse, may enrich the monotonous restricted environment and reduce the high amount of concentrates fed (Goodwin et al., 2007).
