(2) Average Composition of Concentrates. 



Wheat bran contains noticeably less protein than any of 

 the other important by-products. Nitrogen-free extract mat- 

 ter usually is the fodder group next in value to the protein. 

 The quantity contained in bran is approximately equal to 

 that found in gluten feed, and not greatly in excess of the 

 percentage in Ijrewers' grains and malt sprouts.^ Most of 

 the several feeds enumerated contain about similar fiber per- 

 centages. 



(3) Diget^tibilitij of the Concentrates. 



The figures in the following table show the pounds of 

 digestible fodder groups contained in one ton of the several 

 feeds. 



Wheat bran is shown to contain rather less total digestible 

 matter and noticeably less digestible protein than any of the 

 several feeds tabulated. The two carbohydrate feeds, corn 

 and hominy meals, are naturally deficient in protein, but 

 very rich in digestible starchy matter and fat. 



' The quantity of extract matter in cotton-seed meal is quite small, due to the 

 exceptionally high protein percentage.
