[FUN FACT #12]
A horse's teeth include incisors, premolars, molars, and sometimes canine teeth. A horse's incisors, premolars, and molars, once fully developed, continue to erupt throughout its lifetime as the grinding surface is worn down through chewing. Because of this pattern of wear, a rough estimate of a horse's age can be made from an examination of the teeth. Abnormal wear of the teeth, caused by conformational defects, abnormal behaviors, or improper diets, can cause serious health issues and can even result in the death of the horse.
Horses have a relatively small stomach for their size, and this limits the amount of feed a horse can take in at one time. The average sized horse (360 to 540 kg [800 to 1,200 lb]) has a stomach with a capacity of around 19 L (5 US gal), and works best when it contains about 7.6 L (2 US gal). Because the stomach empties when 2⁄3 full, whether stomach enzymes have completed their processing of the food or not, and doing so prevents full digestion and proper utilization of feed, continuous foraging or several small feedings per day are preferable to one or two large ones. The horse stomach consists of a non-glandular proximal region (saccus cecus), divided by a distinct border, the margo plicatus, from the glandular distal stomach, which is further divided into the fundus and pylorus.
