or factory by-products must be added to the ration. The 

 grains most commonly fed are corn, oats, barley, and rye. The 

 by-producte used extensively are wheat bran, wheat middlings, 

 linseed meal, cottonseed meal, gluten meal, gluten feed, hom- 

 iny feed, brewers' grains, malt sprouts, distillers' grains, beet- 

 pulp, molasses, buckwheat middlings, cocoanut meal, and 

 peanut meal. 



In making up a grain mixture for the cattle, many factors 

 must, of necessity, be considered. A few simple rules and direc- 

 tions and a number of grain mixtures as given by the Dairy 

 Division of the United States Department of Agriculture are 

 printed herewith : 



1. Make up the mixture to fit the roughage available. With 

 roughage entirely of the low-protein class the grain should contain 

 approximately from 18 to 22 per cent of protein, while with exclusively 

 high-protein roughage the grain ration need contain only about 13 to 

 16 per cent. 



2. Select grains that will furnish the various constituents, especially 

 protein, at the least cost, using home-grown grains if possible. 



3. Be sure that the mixture is light and bulky. 



4. The mixture should be palatable. 



5. See that the grain has the proper physiological effect upon the 

 cow.
