The efficacy of live yeast in horses

Horses are trickle feeding herbivores, nomadic in nature and who have evolved to ingest small, fibre-rich meals on an almost continual basis. As hind gut fermenters, horses rely on a symbiotic relationship with bacteria and other gut flora, to digest the fibrous portion of their daily ration. Too much starch in the diet increases the risk of colic and laminitis. The addition of yeast to the diet may help in managing these problems. By Catherine Hale, Equine   Research and Development
