Oils may be added to the diet as a source of ‘non-fizzy” feed. When starch (typically in the form of grain), is fed to horses in large quantities, there is a risk of starch overload in the hindgut. This can culminate in “fizzy” behavior, which can result in stressful and dangerous situations for both horse and rider. The risk of starch overload can be minimized by replacing some grain in the feed with oil to provide energy. Oil provides a source of ‘cool’ energy, which is not associated with ‘fizzy’ behavior.
