The reports of these analyses usually show the percent of total dry matter and water, and the per cents of FEEDS AND FEEDING 309 protein, carbohydrates, fat, and mineral matter (Fig. 208).Such reports are very valuable to all stock feeders, as thefigm-es indicate as clearly as is possible the feeding value ofeach kind analyzed. Those feeds, rich or poor in any oneingredient, as protein, may be easily compared in the pub-lished tables. (See Appendix.)

Any one alone, as starch or fat, is unableto completely nourish the body and maintain life. Animals are incapable of making very great changes inthese feed compounds. Each is changed into similar animalproducts in the living animal by a series of processes calleddigestion, circulation, respiration, secretion, and absorption. Loss in These Processes.—In these five processes oflife, digestion in particular, the substances contained in the 310 PRO
