The cows consiuned slightly less haj during the molasses beet 

 pulp half of the trial. It will be noted that hay, bran and cot- 

 tonseed meal constituted the basal ration, and that 4.33 pounds 

 of corn meal were compared with a like amount of beet pulp.

It appears that the two rations contained substantially equal 

 amounts of total digestible nutrients and ought to produce about 

 the same amount of milk. The molasses pulp ration contained 

 rather more fiber, but the excess being derived from beet pulp 

 should not have required much more energy for its digestion 

 than the extract matter. These nutrients fed correspond quite 

 closely to the Haecker standard as stated above. They are not 

 quite as liberal as those recently suggested by Savage. If the 

 basal ration of hay, bran and cottonseed meal fed had been a 

 little less, it would have brought out a trifle more sharply the 

 difference — if any — in feeding value between the corn meal 

 and the molasses pulp.
