It will be noted that the plain pulp contained about 9 per cent of 

 water, a relatively large amount of fiber, and practically no fat. 

 In chemical composition it differs from corn meal in having much 

 more fiber, less extract malter and much less fat. The percent- 

 age of sugar present is small, the larger part of the extract matter 

 being in the form of the hemi-celluloses. The molasses pulp con- 

 tained considerably more ash, due to the large amount of mineral 

 matter in the molasses. The fiber content was noticeably less 

 than that of the plain pulp, due to the replacing of the pulp by 

 the molasses, which was without fiber. They are, however, carbo- 

 hydrate feeds of the same chemical type of composition as corn.

The above figures show that a ton of the corn meal with sub- 

 stantially 11 per cent of water contains about 8 per cent more 

 digestible organic nutrients than a ton of the plain beet pulp hav- 

 ing 9 per cent of water. One would not, therefore, expect to note 

 a marked difference in the effect of these several feeds when used 

 as a component of grain rations intended for milk production.' 



Beet Pulp as a Substitute for Corn Silage. 



Wing * compared the wet pulp with com silage, feeding 50 to 

 100 pounds daily, together with 8 pounds of grain and 6 to 12 

 pounds of hay, and concluded that the dry matter in the pulp was 

 of equal value, pound for pound, \\4th the dry matter found in 



' Calculations on the basis of net energy values show the corn meal to have 45.6 per 

 cent more energy than the plain pulp. This is due to the loss of energy assumed to be re- 

 quired to digest the fiber in the pulp, and, according to Kellner, to the extra energy re- 

 quired for its mastication. Kellner states that the dried pulp has about the same energy 

 value as bran, but noticeably less than the cereals and oil cakes. Probably the larger the 

 amount of dried pulp fed the greater would be the difference in its feeding effect as com- 

 pared with corn meal.
