42, : REPORT OF THE DIRECTOR OF THE 
Fat or Oil. — All are familiar with the nature of the oils from 
foods like cotton-seed oil, corn oil, linseed oil, etc. They serve the 
same purpose to the animal that the nitrogen-free extract does. 
One pound of oil will furnish nearly as much heat as two and one- 
half pounds of starch or carbohydrates. 
Crude Fiber is the woody portion, and paper, sawdust, ates are 
good illustrations. The nutritive value of fiber is small, but 
mechanically it serves a useful purpose in foods for animals that 
“chew the cud” or remasticate their food. Observe in the sam- 
ples the large amount of fiber in hay and the small amount in corn 
meal. | ; 
The eight foods exhibited have about the following chemical 
composition, or in 100 pounds of each food there are as shown 
below:
