actual value as indicated by the availability of the 

 digestible nutrients, the following method is pur- 

 sued: Multiply the digestible protein by its starch 

 equivalent; add to this the digestible carbohydrates, 

 fiber, and the fats after the fat has been multiplied 

 by its starch equivalent; then multiply this sum by 

 the coefficient of availability. The arithmetical re-

suit will be the actual starch value. To illustrate : 

 In linseed oil cake containing 34.5 pounds of 

 digestible protein, 26.1 pounds of digestible carbo- 

 hydrates and fiber and 8.4 pounds of fat what is 

 the actual starch value of 100 pounds of the fresh 

 substance? The process is as follows: 



( (34-5 x .94) + 26.1 + (8. 4 x 2.4) ) x -97 = 76.3 



Thus the actual starch value of 100 pounds of lin- 

 seed cake is 76.3.
