38 FEEDING VALUE OF CEREALS. 



varieties are especially adapted for use as feeding barleys, having a 

 high protein content, a narrow nutritive ratio, and at the same time 

 a high production value. 



Table XXX gives the varieties of barley considered in the order 

 of their protein content, together with their production values and 

 nutritive ratios. 



TABLE XXX. Barleys arranged in order of protein content.

a Figures in parentheses express order according to production value. 



It will be noticed that the order of the nutritive ratio is exactly the 

 reverse of that of the protein content ; that is, the higher the protein 

 content the lower or narrower the nutritive ratio. This is, of course, 

 as would be expected. In regard to the production value, while it is 

 true that the foreign samples with low protein and correspondingly 

 high carbohydrate have the higher production value, some of the 

 domestic samples with high protein have also a high production value. 

 This is due to the fact that the fat content is high or the crude fiber 

 low and is especially noticeable with the varieties Kitzing, Swan 

 Neck, Hanna, and Princess. 



Some individual cases may be noticed showing the maximum and 

 minimum limits in protein content, etc. The highest protein content 

 of all individual samples, excepting the hull-less varieties, is found in 

 No. 1102, Hanna, South Dakota, 1904, third crop after introduction, 

 total protein, 19.94 pounds per 100 pounds; digestible protein, 13.61 

 pounds. The production value of this sample is 20.59 pounds flesh 

 gained and the nutritive ratio is 1: 5.2. The lowest protein content 

 occurs in the case of No. 1185, Princess, California, 1902, first crop 

 after introduction, the total protein amounting to 8.44 pounds, and 

 the digestible protein to 5.91 pounds, the production value being 

 21.32 pounds of flesh gained and the nutritive ratio 1: 13.6. The 

 highest production value is found for No. 1215, Giant Winter, Oregon, 

 1904, second crop after introduction, the production value being
