30 The Sweet Potato 



length of time the cows fed sorghum silage, wheat bran 

 and cotton-seed meal produced 2415.8 pounds or 280.9 

 gallons of milk, a difPerence of 225.2 pounds or 26.2 

 gallons of milk in favor of sweet potato silage. 



" One noticeable fact in this experiment is that the 

 cows ate one-third less sweet potato silage than sorghum 

 silage. This is quite a saving in the amount of feed 

 consumed by a herd during the year." 



Scott of the Florida Station is very enthusiastic over 

 the silo as a means of preserving the crop for the dairy 

 cow. He gives the advantages of preserving as ; " No 

 loss in storage ; they require less space for storage ; 

 and there is no waste in feeding." It is possible that 

 this form of silage will come into more general use 

 throughout the South when more is known of its feeding 

 values. 



Roots. 



The roots without any special preparation are grown 

 extensively throughout the South for feeding purposes, 

 especially for hogs. The Tuskegee Experiment Sta- 

 tion of Alabama found that hogs put on almost as 

 much fat with sweet potatoes alone as with wheat shorts 

 alone. ^ This station also found that a grain ration of 

 corn could very economically be cut in half by sub- 

 stituting from 2% to 3% pounds of potatoes for 1% 

 pounds of corn in feeding mules doing heavy work. 

 Four mules were used in the test. They kept in as 

 good condition and were able to do as much work as 

 the four check animals which were fed corn exclusively. 



Planted in June and early July, they will be ready
