. Animal husbandry. Livestock. 20 COMPOSITION OF THE ANIMAL BODY and sheep have four so-called stomachs, although the first three are only enormous distentions of the gullet. These parts are called the rumen or paunch, the honeycomb or reticulum, the many plies or omasum, and the abomasum or true stomach. In the last named, regular digestion takes place. In the first three named, especially in the paunch, there is room for vast quantities of rough feed. Here the rough feed lies for a time until it is regurgitated, chewed, swallowed the second time, and passed to the third stomach or manyplies.

In the paunch, there is gener- ally a great evolution of gas, due to bacterial fermentation. Under ordinary con- ditions, these gases are taken up by the blood circulation and expelled from the body through the lungs. Often when large amounts of green, dew-laden clover or alfalfa are taken into the paunch, the evolution of gas is greater than the blood can dispose of and bloat or hoven occurs. If not relieved, the animal becomes greatly dis- tressed, and the toxic or poisonous properties of these gases may cause sickness or death. Fats. —? The fats are not so readily changed by the digestive fluids as are the proteins and the carbohydrates. As they pass along they are first acted upon by steapsin (an enzyme secreted by the pancreas) and converted into soaps. Fats themselves are not soluble and are.
