Analysis of Roots

Similarly for the woody fibre. 



Having obtained the percentage of crude fibre, or insoluble 

 matter, we have only to subtract that number from 100 to 

 obtain the percentage of juice, which contains all the water 

 and soluble matter. 



Next reduce all the numbers calculated as percentages of 

 the juice, crude fibre, and dry matter to percentages of the 

 root, exactly as in the case of grass (paragraph 167). 



Make the following additions and subtractions : 



Crude fibre — (woody fibre + insoluble ash + insoluble albuminoids) 

 m digestible fibre. 



In this analysis neither the water nor the woody fibre was 

 estimated separately.
