CHAPTER III 

 CLASSES OF FEEDING STUFFS 



Feeding stuffs are usually classified as roughages, con- 

 centrates, and root crops. 



Roughages. — Roughages are bull£y feeds that come 

 from the grasses and forage crops. They have a low 

 amount of digestible material in proportion to their weight. 

 Included under the head of roughages are the grasses, the 

 legumes, the straws of different cereals, silage, and stover. 



Concentrates. — Included under this head are the cereal 

 grains, the oil-bearing seeds, and a lafge number of so- 

 called by-product feeding stuffs from the following sources : 

 the milling of grains, the manufacture of cereal foods, 

 starch, sugar and glucose, and the extraction of oils, and 

 the slaughtering of animals. Concentrates are just what 

 the name implies, concentrated feeds, since they are high 

 in the easily digested nutrients. 



Roots and Tubers. — This group of feeding stuffs in- 

 cludes a large number of crops that form a valuable source 

 of food for animals in countries where corn cannot be 

 successfully grown. Root crops may be considered as 

 very succulent concentrates. 



The Grasses. — Grass is the natural diet of all our 

 domesticated live stock and the experienced feeder knows 

 that the more he keeps his stock on a diet which closely 

 resembles grass pasture the more successful his feeding.
