Sweet potatoes. — The Alabama, South Carolina, Maryland, ami 
Florida stations have experimented with sweel potatoes with some- 
whal varying results. 
Ai the Alabama Station, Duggar fed <>n<' lot of pigs on a ration of 
three-fourths sweet potatoes and one-fourth ground cowpeas an 1 
another on a ration of equal parts of corn meal and cowpeas. After 
four weeks they were pu1 through an intermediate period <»f <>n.- week 
and the rations were reversed, the lot that had formerly been on corn 
meal and cowpeas receiving the sweet potato ration. This was con- 
tinued for four weeks longer, so that in all there were eight weeks 1 
feeding on a sweel potato ration. 
The ration of sweet potatoes and cowpeas proved very inferior to 
the ration of corn meal and cowpeas; the increase in live weight was 
Dearly twice as great in the case of coin meal and COWpeas, and the 
dry matter pei- loo pounds of gain was est imated at 600 pounds where 
sweet potatoes were fed to .'Mo pounds where com meal was fed. 
Duggar refers to the difficulty of inducing the pigs to eat enough dry 
mailer when sweet potatoes made up 80 much of the ration, and sug- 
gests a ration of equal parts of cowpeas and sweet potatoes as being 
more palatable and nutritions. He questions whethei sweet pota- 
toes can be profitably grown, stored, ami fed to hogs unless the 
feeding value per bushel would he more than l<» or L5 cents. Where 
the pi°;s do the harvesting, especially on sandy soils, where the yield 
of sweet potatoes is ten or fifteen times thai of corn, they may he an 
economical feed. 
The results at 1 he Sont h Carolina Stat ion were much more favorable 
to sweet potatoes. Newman and Pickett * U^\ a lot of :; pigs, averag- 
ing 162 pounds in weight, on sweet potatoes only for forty-three days, 
beginning November 23. Ai the same time corn was U^\ to •'! pins. 
averaging L56 pounds in weight. Two pigs in each lot were high- 
• !<• l'.erkshires and the third was a grade Duroc Jersey.
