85. in lUO pounds of wheat bran there are 15.4 

 pounds of protein; 79 (coefficient of digestibility) per 

 cent of which, when eaten, is digested. How many 

 pounds of protein are digested? 



15.4 X .TO = 12.17 



86. The composition and coefficients of digestibility of 

 corn stover are as follows : 



How many pounds each of digestible protein, carbo- 

 hydrates (fiber and starch), and fat in 100 pounds? 



87. In 100 pounds of cottonseed meal there are 42.3 

 pounds of protein; of this 37.2 are digested. What is 

 the coefficient of digestibility? 



88. The number of pounds of digestible protein in a 

 ton of clover hay is 136. When clover hay contains 12.3 

 per cent of protein, what is the coefficient of digestibility? 



89. Wheat bran contains 9 per cent crude fiber of 

 which 22 per cent is digestible, and 53.9 per cent of nitro- 

 gen-free extract, of which 69 per cent is digestible. What 

 is the percentage of digestibility of each constituent? 



90. In 600 pounds of wheat bran, what is the total 

 digestible quantity of each of these constituents? 



The important three compounds. Protein, carbohy- 

 drates (nitrogen-free extract and fiber), and fat are the
