85. In 100 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 -79 = 12.17 



86. The composition and coefficients of digestibility of 

 corn stover are as follows : 



DIGESTIBILITY OF CORN STOVER. 



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 co-efficient 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
