Henry and Morrison : Feeds and Feeding. no PRODUCTIVE AGRICULTXJRE This similarity of the chemical composition of animal bodies andplants may be compared by studying the following diagram: DENT CORN, GRAIN, -^^.M ,ll WHEAT. VILFALFA BLUE FED OX. WELL FED SWINE ^^^^^ 53. BODY OF CHICKEN. HILK From the above diagram it may be seen that plant and animal tissue is somewhatsimilar in chemical composition. It may be noted, however, that plants contain a greatdeal of carbohydrate material, and that animals contain no carbohydrates. On the otherband, it may be observed that animal bodies contain a greater amount of protein materialin proportion to the total dry matter found in animal tissue than is found in plant tissue,There is generally a greater proportion of fat in animal bodies than in plant bodies. Comhas per cent fat, and a well-fed pig has per cent. Corn has per cent carbo-hydrates, and the well-fed pig has none. As we shall see in a following paragraph, the carbo-hydrates are used for producing heat energy and fat. The diagram deserves close stud/.The figures show the percentage of nutrients found in each article given. FEEDS AND FEEDING iii Function of Food Materials. — Water is used to build up bodytissue.
