SWILL TUB AND CORN CRIB. 59 



The dairy wastes are all excellent hog foods. 

 Skim-milk heads the list, but is often wasted. Butter- 

 milk is of about the same value as skim-milk. Whey 

 is of less value, though fattening. 



The wheat waste products, especially the mid- 

 dlings and shorts, are deservedly held in high esteem, 

 as they are especially rich in muscle-making elements. 



Linseed or flaxseed meal, including both old and 

 new process, is very high in muscle-forming ele- 

 ments. The cake when ground and fed to stock 

 makes excellent food. It is somewhat laxative in its 

 effect. Cottonseed meal, on the other hand, though 

 high in its protein (tissue-forming elements) is con- 

 stipating in effect. The approximate character and 

 values of the more common mill feeds are indicated 

 by figures tabulated in another chapter. 



Corn, in its various forms, including fodder and 

 ensilage, is perhaps the most prominent of American 

 hog feeds. It is a grand thing in every form, a price- 

 less boon to the agricultural public, but alone it is not 

 a perfect food for swine or other stock. It is highly 

 carbonaceous ; that is, it is rich in sugar and starch, 

 and is limited in its ability to produce lean meat, bone 

 or milk. Its function is fattening and heating. When 

 balanced with nitrogenous foods, and supplemented 

 by any sufficiently bulky provender, it makes a perfect 

 food for live stock. It will always have a prominent 

 position in American feeding. 



No better practice has yet been suggested than a 

 hog diet consisting first of milk, then of grass and 

 middlings, and finally of corn. I do not mean that 

 these things should be the sole diet of the rapidly
