Next in importance to the quantity of food is the frequency with which it should be given. It should always be remembered that the peculiar anatomical structure of the digestive organs in the horse, as well as the nature of the digestive process in that animal, necessitate food being given at regular and frequent periods. Nothing conduces to health and efficiency more than the observance of the rule by which food is allowed at periods suited to the requirements of the digestive functions. Perhaps no animal suffers more from long fasts than the horse; and disease or disorder of the digestive organs is a common occurrence in stables where long fasts are succeeded by heavy feeding, as digestion is impaired by the food being devoured greedily, and in larger quantity than the stomach can properly accommodate. Horses should be fed at least three times a day; better if it could be four times. The hour at which the morning feed should be given will depend more or less upon the time for turning out for work; there ought to be ample leisure for consuming the meal before that occurs. At any rate, the first feed should not be later than six or seven in the morning; the next towards mid-day; and if only fed three times a day, the third in the evening. If possible, no longer interval than four hours should elapse between the meals; and while those given during the day should be moderate in quantity, that allowed at night ought to be the largest, as the horse then has ample time for mastication and rest. During the day a little food, however small the quantity, is better than none; and for heavy horses, and even for light ones when it can be carried, a nose-bag containing a feed is a most advantageous addendum to the equipment. If the hay is given long or uncut, the bulk of it should be reserved for night consumption. An important point in feeding is to apportion the feeds in such a way that each will be consumed at the time it is given; as if any is left in the manger it becomes stale or sour, and the horse does not care for it afterwards. This is most frequently the case with chaff which has been wetted in the manger - a good practice, as it is easier masticated, but it has the disadvantage of spoiling any food which may be left, and also necessitates the frequent washing out of the manger.
