TABLE XVII. Comparison of domestic and. foreign grown oats of the same varieties. 

 [Per hundred pounds of dry matter.) 



a The United States grown Shatilov has less protein than the foreign. 



b The United States grown North Finnish Black has a broader nutritive ratio than the foreign. - 



In considering this table it will be noticed that while in most cases 

 the number of domestic samples was considerably larger than the 

 number of foreign and in two cases only one sample each was ana- 

 lyzed, still the comparison is even more striking than in the preceding 

 table. The general statement that the domestic oats contain more 

 protein and crude fiber and less fat and carbohydrate with a lower 

 total production value and a narrower nutritive ratio is upheld by the 

 results in this table with two exceptions. Of the variety Shatilov, 

 only one sample each of domestic and foreign origin having been ana- 

 lyzed, the domestic grain fell below the foreign grown in protein con- 

 tent though it showed the characteristic composition in all other 

 points. The North Finnish Black domestic-grown oat showed the 

 characteristic distinction from the foreign grown in all the nutritive 

 constituents and in the production value, but in the nutritive ratio it 

 differed by being broader, not narrower, than the foreign-grown grain. 



These characteristic differences, as shown by average results, are 

 exemplified in a striking way by some individual cases, though, of 

 course, there are also some marked exceptions. The group averages 

 for protein content of domestic and foreign oats show a higher protein 

 content for the domestic samples (Table XVIII, p. 24), and the com- 

 plete table of individual data (Table XXXVIII, p. 48) shows that of 

 the 54 foreign-grown samples there is only one that has a protein 

 content above the average of the domestic grain. This is No. 1224, 

 North Finnish Black grown in Finland, with digestible protein per 

 hundred pounds amounting to 12.33 pounds, the average of all United
