DISCUSSION OF RESULTS.

The same general facts are again shown as were found in the case 

 of the oats, namely, the foreign-grown grain is poorer in protein and 

 richer in carbohydrate; higher in production value and broader in 

 nutritive ratio. A comparison of individual varieties (Table XXIX), 

 of which both foreign and domestic samples were analyzed, shows 

 the same relations to exist. 



TABI.K XXIX ' <>m prison of domestic and foreign barley, averaged by varieties. 

 [Pounds per hundred pounds of dry matter.] 



In even rase \shere I IK- -ame variety was grown in its original 



_rn home and then later in the United States it increased in 



protein and the nutritive rat io heraine narrower, while the production 



value denva^rd \er\ -lightly. The resulting effect, therefore, is the 



production of a better feeding barley than the original. 



An examination of the table of averages for barley (Table XXXI) 

 will show that the maximum protein content was found in the two 

 United States >ample> of Kit/ing, namely, total, 15.25 pounds per 

 inn pounds or 10.67 pound- digestible, the carbohydrate in the 

 same -ample bring 7~>.~)(> pounds total and 69.51 pounds digestible. 

 The InwrM protein content, on the other hand, was found in the 

 right forrign-gmu n -amplrs. namely, 12.52 pounds total and 8.76 

 pounds digeMihle. the carbohydrate in the same samples being 

 7vn:> pounds total and 71.78 pounds digestible. The production 

 value of the I'nited Shite- Kit/ing was 21.03 pounds of flesh gained 

 or '.MI. '.ML* Caloiiee and of the foreign samples 21.19 pounds of flesh 

 gained or 91,604 Calories, the nutritive ratio being 1:7.0 for the 

 domestic and 1:8.8 for the foreign. It is noticeable that in this 

 variety Kit zing) the protein content is the highest of all, while at 

 the -a me time the production value is only slightly lower than that of 

 the foreign-grown grain. The same can be said in general of the 

 varieti.- >\\ ; m Nrek. Ilanna, and Princess. This means that these
