In their percentage composition, the several brands closely 

 resemble wheat bran and likewise each other. The Holstein feed 

 contained rather less protein and more extract or starchy matter 

 than the others. The protein in this class of feeds is derived prin- 

 cipally from malt sprouts, cottonseed meal and gluten feed ; the fibre 

 particularly from the cereal residues, and the extract matter largely 

 from the cereal residues and from the molasses. The carbohydrate 

 matter consists of sugar, starch and pentosans. 



DIGESTIBILITY. 



Digestion experiments with sheep were made with the several 

 molasses feeds and the resulting coefficients follow : 



Figures equal percentages of the dififerent ingredients digestible. 



Applying the above coefficients to the percentages or pounds in 

 100 contained in the different brands and multiplying the results, by 

 20, one secures the data in the next table. 



*^ Macon was a brand furnished by Chapin & Co. of St. Louis. In chemical composition 

 and appearance it resembled the Green Diamond.
