BEET RESIDUES FOR FARM STOCK. 



BY J. B. LINDSEY. 



1. Dried Beet Pulp. 



Dried beet pulj) represents the residue in the manufacture of 

 sugar from sugar beets. It is first run through presses to reduce 

 its water content as much as possible, and then put into kilns 

 where it is thoroughly dried by direct heat. 



Composition of tlie Product. 



The prepared product is very dry, coarse and of a grayish 

 color. It contains substantially 9 to 12 per cent, of water, 

 about 4 per cent, of ash, 8 per cent, of protein, 18 to 20 per 

 cent, of fiber, 00 per cent, of extract matter and less than 1 per 

 cent, of fat. The fiber is quite soft, being free from incrusting 

 substance and hence quite digestible. 



Digestihillty of tlic Dried Pulp. 



Xo digestion experiments made in this country are recorded. 



German experiments show it to have a digestibility of 77 per 



cent. ; corn silage made from mature dent varieties shows an 



average digestibility of 66 per cent. ; and corn meal 88 per cent. 



Dried Pulp as a Substitute for Corn Silage. 

 Wing^ compared the wet pulp with corn 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 j^ound, with the dry matter found 

 in the silage. The milk-producing value of wet beet pulp as it
