Pages 15-16 The Cedar Rapids, Jenks and Bay State 



brands contained less protein than the 

 average, due not to adulteration but to the fact thay they con-

 cannot be considered as economical sources of protein for the 

 dairy ration as the other brands.

Distillers dried grains are the dried residue 



Distillers' Dried obtained from cereals in the manufacture 



Grains. of alcohol and distilled liquors. Owing 



Page 16 to their bulky nature they may be used to 



replace bran in the ration, one pound of 

 corn distillers' grains being equivalent to about 11-2 pounds of 

 bran in feeding value. The grains derived from corn are the 

 most valuable while those derived from rye have the least feed- 

 ing value. Twenty-two samples of corn grains, 2 samples of rye 

 grains, and 2 samples of Dearborn grains whose composition 

 would indicate that they were derived from a mixture of corn 

 and rye were collected. All were of good quality and, aside from 

 a slight variation from guarantee in some cases, were as represent- 

 ed. The brand put out by the Continental Cereal Company is 

 known as Continental Gluten Feed. The product is misnamed 

 inasmuch as it is distillers' grains and not what is commonly 

 Icnown in the market as gluten feed*.
