Due to the vigorous action of the enzymes in the small intestine, digestion is very thoro and under ordinary conditions little that is useful is lost. The larger portion of all the digested matter is absorbed from the small intestine, thus entering the body proper, as is shown later in this chapter. The large intestine.—Prom the small intestine the undigested material passes into the large intestine. Little, if any, digestive fluid is produced here, but a small amount of digestion may go on owing to digestive enzymes carried in from the small intestine and to the action of bacteria. The bacteria may not only attack cellulose but also may cause the putrefaction of undigested protein, in which action foul- smelling substances are formed which are poisonous if absorbed in large quantities. The waste, or feces, is finally expelled from the large intestine. Besides undigested matter, the feces contain residues of the digestive juices and countless bacteria or their remains. If the large intestine is not functioning normally, the contents may remain for an undue time, and excessive putrefaction may take place, injuring the animal thru the absorption of the poisonous products formed. Special provision for the horse.—As has been mentioned before, the horse has a large caecum, or blind gut, in partial compensation for its small stomach and lack of a paunch. The incom- pletely digested matter from the small intestine, together with the enzymes mixed with it, passes into the caecum. Here the en- zyme action continues and the cellulose of the feed is also attacked and digested by bacteria, as in the paunch of ruminants. Due to this
