Horses have evolved as trickle feeders, designed to be chewing or occupied by roughage for a large portion of their day.

However many horses today have a very different environment to the one they would have naturally had. Stabling, travelling, training and high concentrate feeding all work against the horse’s normal gut function and limits fibre input and digestion. This disruption of normal hindgut function can cause an imbalance between the resident beneficial (good) bacteria and any pathogenic (bad) bacteria.
