336 FEEDING FARM ANIMALS 



For swine, sweet potatoes are better adapted to fur- 

 nishing food than for other classes of live stock, as 

 in addition to being very much relished by swine, they 

 are a good food for fattening them, and they may also be 

 harvested by the swine. Being a bulky food, some concen- 

 trated food should be fed along with them. For such feed- 

 ing cowpeas and soy beans are very suitable, but corn may 

 also be fed so as to form one-half the concentrate. When 

 swine are thus fattened on sweet potatoes, they should not 

 be required to glean closely lest the exertion thus made 

 should be too much for the best gains to result. Sucii 

 gleaning should be done by store swine. 



For horses and mules, at work in the South, sweet 

 potatoes are frequently fed. For such feeding they have 

 been found quite suitable when fed sliced along with corn 

 or other grain, in the proportion of say 3 pounds of 

 potatoes to i pound of grain. There would seem to be no 

 reasons why they should not be fed in moderation to foals 

 and to young horses not yet matured, when they can be 

 spared for such feeding. 



Jerusalem artichokes. These may be successfully 

 grown in nearly all parts of the United States and Canada. 

 The tops are sometimes used in providing food tor stock 

 where intensive conditions prevail, but even under such con- 

 ditions, the chief value of the crop lies in the tubers. They 

 are more watery than potatoes, but are richer in protein. In 

 feeding value they have been found fully equal to potatoes, 

 viewed from the standpoint of practical results. Their abil- 

 ity to resist frost without injury adds much to their eco- 

 nomic importance, as it makes it possible to harvest them 

 with swine or otherwise even after the winter has gone. 

 The yields vary greatly with varying conditions, but 200 to 

 300 bushels per acre may be readily grown under average 

 conditions. The persistency with which artichokes remain 

 in the soil is one objection to growing them. 



For cattle, the feeding value of artichokes is much the 

 same as that of potatoes, and about the same quantities may
