DISCUSSION OF RESULTS.

TA u L K X XXII . Group averages of total and digestible nutrients of proso, sorghum, and 



maize. 



[Pounds per hundred pounds ol dry matter.] 



l'ro>o and >orghum. like maize, are lower in protein and higher in 

 carbohydrate, L r i\iiiL: higher production value and broader nutritive 

 ratio than the other cereal- and thus stand at the opposite extreme 

 from oat-. 



Of the prosos (Table XLI Y . the highest protein content is found 

 for No. lo-j-j from Oklahoma, namely, 16.87 pounds, digestible protein 

 ponnd^ per 100 pounds, giving to this sample the narrowest 

 nutritive ran.- 1 vJ ,md the lowest production value, 18.70 pounds 

 gain in tle-h. The hiirheM carbohydrate content was found in a 

 Colorado sample, No. in.".), with 75.22 pounds total and 64.09 pounds 

 diL r -! ihle. This gives a production value of 19.76 pounds gain in 

 llr-h. which i- the hiirhe-t with one exception, No. 1016, for which 

 the nutritive ratio i- 1 : 1 1.6, the broadest of the entire list. The 

 average protein content i- I'J.77 pounds total and 6.28 pounds digest- 

 ible. The average production value and nutritive ratio are, respec- 

 tively. 19.37 pound- L'ain in llesh, or 83,736 Calories, and 1:11.5. 



Of the sorghum- the hiirheM protein content is in No. 771, which 

 has 14.50 pounds total and '.. U pounds digestible, the nutritive ratio 

 being relatively narrow, namely. 1:8.2. The highest carbohydrate 

 content i- found in Xo. 770 with 85.31 pounds total and 77.64 pounds 

 digest ihle. This sample has a production value of 21.71 pounds gain 

 in tle-h. the maximum being 21.87 pounds in No. 781. It has the 

 bmade-t nutritive ratio of any of the samples examined, namely, 

 1 :14.3. Tin- average composition of the sorghum samples is given in 

 Table XXX111.
