BULLETIN 4*70, IT. S. DEPARTMENT OF AGRICULTURE. 



In the diet containing large quantities of milo bread, the bread sup- 

 plied an average of 36 grams of protein and 251 grams of carbohydrate, 

 which were estimated to be 40.0 per cent and 96.3 per cent digested, 

 respectively. In these experiments, as in the tests with the other 

 sorghums, owing to the low protein content of the grains, it would 

 have been very difficult for the subjects to eat a sufficient bulk of the 

 diet to obtain the amount of protein specified in the common dietary 

 standards, namely, 100 grams per man of average weight daily. 



DIGESTION EXPERIMENTS WITH KAOLIANG BREAD. 



Kaoliang bread, or, perhaps better, gingerbread (also flavored with 

 ginger), was very similar in taste and appearance to the other sorghum 

 breads. Indeed, all the sorghum gingerbreads so clearly resembled 

 one another that the subjects apparently believed that they were all 

 prepared from the same meal. The essential data of the digestion 

 experiments with four subjects are reported as follows:
