SUCCULENT AND BULKY FEEDS 253 



potatoes are relished. A Canadian authority reports 

 (Bulletin No. 129, Ontario agricultural college) that 

 "their influence upon the quality of bacon is beneficial." 

 It is ordinarily estimated that four or 4J^ pounds of po- 

 tatoes, when cooked and used in connection with corn, 

 other grain or meal, have a value equal to one pound of 

 grain alone. Potatoes alone cannot be used to advantage 

 as a feed, nor can they be eaten by hogs in any great 

 quantity. They are best relished when cooked and mixed 

 with meal, making of the mixture a rather heavy mush. 

 Skim milk and potatoes go well together. (See experi- 

 ments of Central experimental farm given in the table in 

 Chapter 17.) 



SWEET POTATOES 



Sweet potatoes have been fed to hogs with some de- 

 gree of success, particularly in the southern states, where 

 they have been used l^oth raw and cooked, and the 

 Jiogs have also been allowed to harvest them. Attempts 

 to maintain hogs on them have proved unprofitable, but 

 their value has been apparent when properly balancing 

 a ration. 



The South Carolina experiment station (Bulletin No. 

 52) fed one lot of hogs, averaging in weight 162 pounds 

 each, on sweet potatoes alone, for 43 days, and another 

 lot, averaging 156 pounds each, for the same period on 

 corn. The average total gain per hog was 26.6 pounds 

 on sweet potatoes and 50.6 pounds on corn from an 

 average consumption of 863.7 pounds of sweet potatoes 

 and 305 pounds of corn, thus requiring to produce one 

 pound of pork 32.47 pounds of sweet potatoes or 6.02
