The total ash in niolasses-beet-pulp is noticeably higher than 

 in most carbohydrate concentrates. It is characterized by a rela- 

 tively large amount of potash and lime, and a small amount of phos- 

 phoric acid. Including the nitrogen, the total fertilizer constituents 

 contained in the beet pulp would be approximately 20 percent more 

 valuable than those contained in the corn meal.* 



D. DIGESTIBILITY OF MOLASSES-BEETT^ULP. 



Sample used. Corn Meal. 



Average 3 trials. (For comparison.) 



Dry matter, 85 89 



Protein, 64 70 



Fiber, 84 — 



Extract matter, 91 94 



Fat, — 9 £ 



The experiment, the results only of which are presented, was con- 

 ducted with three sheep and proved the pulp to have a high average 

 digestibility. The sheep appeared to have found little trouble in di- 

 gesting the fiber, which is not surprising in view of the fact that the 

 cell walls of the beet are soft and comparatively free from incrusting 

 substances (lignin). Judgmg from the composition and digesti- 

 bility of molasses-beet-pulp and corn meal, one would feel justified 

 in assuming that there would be no marked differences in their com- 

 parative nutritive value. 



E. FEEDING EXPERIMENT WITH COWS. 



MOL.A.SSE.S-BEET-PULP VS. CORN ME.\L. 



Object of the Experiment : The object of the trial was to note 

 whether the animals ate the pulp freely and its effect upon their gen- 

 eral condition ; the comparative yield of milk, milk solids and milk 

 fat with the two rations, and the consequent economy of the dried 

 pulp as a dairy feed. 



Plan of the Experiment : Two cows, one of which, (Pearl) had 

 been in milk for about a year and the other (Red 11) for two months, 

 being the only ones available at the time, were employed and fed by 

 the alternate method. 



* Because of the relatively small amount of fertilizing ingredients as compared with the 

 nutritive ingredients in the two feeds, this difference is of minor importance.
