200 RESULTS OF EXPERIMENTS IN SWINE FEEDING 
The chufa is more or less a weed in the South, but it produces 
small tubers which hogs eat readily. The Alabama Station 
(Bulletin 122) fed hogs corn and cow-pea meal on a chufa 
pasture. The average of two tests shows 307 pounds of pork 
which can be credited to each acre of chufas after making allow- 
ance for the meal fed. Chufas did not prove as satisfactory as 
peanuts and soy beans for hog pasture (Ala. Bul. 143). Like 
other succulent feeds, the chufa is not a substitute for grain, 
but may often be used to advantage to supplement a grain ration. 
Acorns.—In parts of the South, acorns assume considerable 
importance in feeding hogs. Hogs usually are allowed to run 
in the woods and gather the fallen nuts, which, being a waste 
product, help to cheapen production. The Tuskegee Station 
in Alabama reports feeding 400 pigs successfully on acorns and 
kitchen slop. The pigs were fed about five pounds of acorns 
each, per day. Acorns make a very poor quality of pork and pigs 
should be given several weeks of grain feeding before they are 
slaughtered, to overcome the bad effect of the acorns. : 
Pasture vs. Soiling—Some experiments at the Ontario 
Agricultural College indicate that more rapid gains with 4 
smaller consumption of feed per pound of gain can be secured 
by soiling pigs than by pasturing. This is especially true of 
young pigs, and the writer’s experience leads him to believe 
that pigs should weigh at least 100 pounds before being turned 
on pasture, to get best results. There is considerable extra 
labor in cutting green crops and carrving them to the pigs under 
the soiling system, which brings the two systems fairly close 
together from the stand-point of economy. 
Amount of Grain on Pasture——Growing or fattening pigs 
cannot be produced satisfactorily on pasture alone, but a grain 
ration is necessary. The Montana Experiment Station found 
that hogs fed a full grain ration on pasture gained, on an 
average, 1.59 pounds per hog per day, and required 412
