274 TH E FORAGE AND FIBER CROPS IN AMERICA 



having an endosperm. This endosperm contains aleurone (pro- 

 tein) grains and obliterated cells, but contains no starch. 1 The 

 seeds contain a high percentage of protein and an extraor- 

 dinarily high percentage of fat, being in both respects similar 

 to flax seed and cotton seed. In its high percentage of fat, it 

 is quite unlike other legumes grown for their seed, except the 

 peanut. Where fed to milch cows, soy bean meal has been 

 found by the Massachusetts Station to have a feeding value 

 equal to cotton seed meal, and the Kansas Station found that 

 when it was mixed with either maize meal or kafir corn meal, 

 and fed to pigs, the number of pounds of food required to 

 produce a pound of pork was reduced as compared with either 

 maize meal or kafir corn meal when fed alone. The composi- 

 tion of the whole plant is similar to that of red clover; and, 

 although the soy bean is somewhat less palatable, it is, in the 

 proportion to which it is eaten, similar in feeding value. When 

 placed in the silo, mixed with maize or in alternate layers, it 

 keeps well, is readily eaten and is nutritious.
