178 INDIAN CORN CULTURE. 
economical practice. Atthe Wisconsin station 
a bushel of shelled corn made 11.4 Ibs. of pork 
when fed alone to pigs, while a bushel fed to 
them when running with corn-fed steers made, 
with the help of the droppings of the steers, 
17.6 lbs., or over one-half more. 
Corn-and-cob meal vs. corn-meal.—The 
question is often asked as to which is the more 
valuable food, corn and cob ground together or 
corn-meal alone. Considerable experimental 
feeding has been conducted to throw light on 
this question, and very generally the informa- 
tion secured favors the grinding of the corn and 
cob together. It is assumed that the pure mea! 
packs in the digestive organs and is not so 
readily permeated by the digestive fluids as is 
the corn-and-cob meal, the cob making the 
mass more porous. 
At the Maine experiment station Jordan fed 
two lots of pigs 81 days, one receiving corn- 
and-cob meal, the other pure meal. There was 
but little difference in the gain made by each 
lot. Shelton at the Kansas station found that 
it required 650 lbs. of corn-and-cob meal to 
make 100 Ibs. of gain when fed to pigs, while it 
required 670 lbs. of pure meal to make an equal 
gain. Inasteer-feeding experiment Prof. Shel- 
ton also secured results favorable to the use of 
the cob with the corn. 
General testimony seems to show that a
