Cliemical  Composition. — The  following  tables  on  the  chemical 
composition  of  the  various  parts  of  the  soy  bean  used  for  feeding 
purposes,  have  been  arranged  with  great  care,  to  show  as  far  as 
possible  the  latest  and  best  results  obtained  by  experimenters  in  the 
United  States  during  the  course  of  their  studies  of  this  plant:

If  the  preceding  analyses  are  compared  with  those  of  other  legu- 
minous crops,  it  will  be  seen  that  the  soy  bean  ranks  high  from  a 
chemical  point  of  view.  The  green  fodder  has  much  the  same  com- 
position as  red  clover,  being  slightly  lower  in  crude  protein  and 
higher  in  crude  fiber.  In  the  two  most  important  substances,  crude 
protein  and  fat,  the  soy  bean  is  considerably  richer  than  the  cowpea. 
The  hay  also  shows  a  relatively  high  fat  and  protein  content.  The 
only  available  analysis  of  soy  bean  ensilage  shows  it  to  agree  very 
closely  in  composition  with  red  clover  ensilage,  being  higher  in
