EXPERIMENT STATION.

ash, due to the large amount of mineral matter in the molasses. 

 The fiber content was considerably less than that of the plain 

 pulp, due to the replacing of the pulp by the molasses which 

 was without fiber. The amount of molasses added to the pulp 

 appears to vary more or less in different samples. 



Both the plain and the molasses pulp are carbohydrate feeds 

 similar to corn meal, being relatively low in protein and high 

 in carbohydrates. The extract matter of the molasses pulp 

 contains considerable sugar, while in the plain pulp there is 

 much less sugar and more of the hemicellulose. The carbo- 

 hydrates of the corn meal consist largely of starch, while those 

 of the 1)1 ain beet pulp are made up of a high percentage of fiber 

 together with the hemicellulose and some sugar. . 



Coefficients of Digestibility of Beet Pulp. 

 Three single trials were made with each sample of the beet 

 imlp with the following average results: — 



• German experiments. 

 2 Three earlier trials. 



The coefficients for plain pulp made at this station are rea- 

 sonably close to those of German origin. The molasses pulp 

 shows higher coefficients than the plain pulp. Part of this is 

 due, however, to the high ash percentage and its increased diges- 

 tibility.
