Document Summary
Safety mechanism to prevent lethal stomach rupture, since horses can" It is estimated that a horse spends about 10 to 17 hours each day grazing, and this periods. Peak grazing just before dawn and just after dark. Horses without free access to pasture eat much more in one sitting. Stabled horse: can"t vomit this is broken up into about 15 to 20 grazing. So the git doesn"t work well if fed more than few pounds of grain in a meal. Too high in starch (horse doesn"t have enough enzymes) Some grains better than others because of starch digestion. Starch in oats is easily digested by enzymes in foregut, so it doesn"t con. Dense starch can overload gut bacteria -> starch digesting bacteria in hind gut prod fiber digesters die when ph is too acidic -> release toxins -> colic and founder. Feeding 5 lbs or less of grain reduces risk of colic and founder.
