The duration of stomach digestion varies. A hay ration requires six to eight hours; one of oats, five to six hours. When no other food is given, the stomach empties itself in fifteen to twenty-four hours. A sudden change of diet retards digestion and thus predisposes to indigestion and fermenta- tion. The food undergoes a sort of churning motion and becomes mixed toward the pylorus. After entering the left sac it is rapidly forced to the right side and its passage into the small intes- tine, regulated by a constrictor or sphincter muscle around this orifice, is rapid at the beginning of feeding and then slows until the stomach is about two-thirds filled. In this state, digestion is most active; over-distension arrests it. After this period the outgo equals the income until digestion is completed. The stomach, being small, empties itself two or three times during a meal. Different foods leave the stomach successively in the order fed. Hence, since proteid digestion is the principal function of the gastric juice, proteid concentrates, as oats, should be given after the hay to secure the benefit of prolonged stomach digestion. The incorrect practice of giving grain first is partly mitigated by some hay remaining in the stomach from the previous meal and retarding the passage of the grain into the intestine. Water may pass into the intestine two minutes after drinking, and car- ries with it some undigested food. Horses should be watered before feeding. The stomach of the ox is divided into four compartments :
