Evidently the foods rich iu protein do not sell at a correspondingly 

 higher price and a dollar invested in some of the oil meals for in- 

 stance, will buy almost as many pounds of digestible material as it 

 would spent for bran and will at the same time secure a much 

 larger amount of digestible protein. 



A grain ration of equal parts by weight of wheat bran and corn- 

 meal is a first class feed for the. dairy cow and has probably been 

 used more than any other one grain mixture. Years ago when bran 

 was cheap, this was an economical ration, but under the present 

 high prices it is possible to make a cheap mixture. A ration of 

 four pounds of bran and four pounds of corn meal would contain: 



Four pounds bran. 

 Four pounds corn.
