The grains run high in nitrogen free extract due to the large 

 amount of starch present. The starch content also predominates 

 in the dry matter of potatoes.

The grain of corn is exceedingly high in carbohydrates (starch) 

 and advantage of this is taken in fattening animals which we 

 will speak of later. The starch of this grain is employed com- 

 mercially in making corn starch and corn syrup. 



Carbohydrates in Animals. — Glycogen which is found in the 

 liver and muscles, and milk sugar found in the milk of mammals 

 are the only carbohydrates in the animal body that we know 

 of. The carbohydrates of plants are changed to fats in the 

 animal body. Carbohydrates therefore do not occur in the ani- 

 mal body to such a large extent as in plants. 



Crude Fiber. — The woody parts of plants are called crude 

 fiber. Cotton lint is almost pure fiber. Crude fiber is made up
