121.7:2. The nutritive ratio in this case is 1: 12.4 and the digestible 

 protein amounts to 6.56 pounds. No. 1165, Beldi, South Dakota, 

 1 .)()."). third crop after introduction, shows the lowest production 

 value, namely 'JO. 24 pounds of flesh gained, the nutritive ratio in this 

 being 1:6.2, and the digestible protein, 11.37 pounds. From 

 the>e cases and from an examination of the complete table (Table 

 X 1.1 1 1. (> "> s it will he seen that, as has been stated, a high pro- 

 tein usually corresponds to a low production value and a narrow 

 nutritive ratio. In the cases just cited the barley having the highest 

 protein content has a production value only a little higher than the 

 lowest and, vice versa, the one having the highest production value 

 ha> a protein content only slightly higher than the lowest. 



Therefore, for the best feeding barleys, it is essential to secure in 

 one >amj>Ie or variety a high protein and narrow nutritive ratio, while 

 at the same time the production value remains high. For barleys, 

 then, as for oat>. the general conclusion is that the effect of introduc- 

 tion appears to be to increase the protein content and to narrow the 

 nutritive ratio.. At the same time the total production value is 

 slightly diminished, but in even a less degree than in the ase of oats. 



The eU'ect of the introduction has been therefore to improvfe the 

 baileys as a feeding grain, the tendency being toward the production 

 of those characters, mentioned in the preceding paragraph, which are 

 ntial to the best l>aile\> for such purposes.
