The left portion is lined with a cnticuhtr mucous membrane, and the right portion with a glandular mucous membrane that has in it the glands that secrete the gastric juice. The most important digestive change in the feed is the action of the gastric juice on the proteids and their conver- sion into the simpler products, proteoses and peptones. Ruminants have a compound stomach (Figs. 9 and 10). The capacity of the stomach of the ox is between twenty and thirty gallons. The four compartments into which it is divided. Fig. 10.—AvSection of the wall of the rumen and reticulum, showing the oesophageal groove: (C, C) lips of groove; (B) opening from cesophagus; and (A) opening into omasum. are the rumen, reticulum, omasum, and abomasum or true stom- ach. The rumen is the largest compartment, with a capacity of more than twenty gallons. The reticulum is the smallest, with a capacity of about one-half gallon. After a brief mastication, the food passes directly to the rumen. Here it is subjected to a churning movement that mixes and presses the contents of the rumen forward in the direction of the oesophageal opening, where it is ready for regurgitation. It is then carried back to the mouth, remasticated and returned.
