Feeding Bran to horses for energy?

Bran is what you would call "natures broom". It is not an energy booster. It is a way of helping the manure move through the body. Now, if you feed toooo much of it, your horse will have the runs and could continue to dehydration. I do not know your horse, maybe he needs bran everyday i don't know. I have never worked in a horse barn that fed it more than once a week. and it can be used on a colicy horse (that is if the horse will even eat it by then.) It is also fed to mares who have just foaled out to help keep their bowels up to speed.
