comes from the factory ^ is, pound for pound, about one-half that 

 of corn silage. 



Billings - comj)ared the dry pulp with corn silage, and con- 

 cluded that the pulp ration gave 10.2 per cent, more milk than 

 did the silage ration ; but, because of the cost of the dried pulp, 

 it was more economical to feed silage. In his trial the cows 

 receiving the pulp ration lost in flesh. 



The fact must not be overlooked that the dried pulp is a car- 

 bohydrate, similar in chemical composition to corn silage and 

 corn meal. It is believed that 5 tons of silage is substantially 

 equivalent in feeding value to 1 ton of the dried pulp. Putting 

 the value of the 5 tons of silage at $20, the ton of pulp should be 

 bought for the same money, whereas its present cost is some $2G. 

 It is believed, under present conditions, not to be good economy 

 for farmers to buy pulp to be used in place of home-grown corn 

 silage, the farm being the place for the production of carbohy- 

 drate food stuffs. 



Beet Pulp as a Suhstitute for Corn Meal. 



On the basis of digestible dry matter in dried pulp and corn 

 meal, the former is worth 90 per cent, of the latter. According 

 to Kellner the dried pulp has substantially 80 per cent, as much 

 value as corn meal. 



2. Dried Molasses Beet Pulp. 



Beet pulp, after it has been pressed to remove the excess of 

 water, is mixed with residuum beet molasses and the mixture 

 put into driers where it is thoroughly dried by direct heat. 

 This product, similar to the plain pulp, is quite dry, coarse, 

 and resembles in its appearance ordinary black tea. 



Composition and Digcstihilihj. 

 The molasses beet pulp does not vary much in the percentages 

 of the several fodder groups from ordinary pulp. It usually 

 tests slightly higher in protein and ash and a little lower in fat. 



1 Only thopc livin;? in the imincdintc vicinity of tlie factory can afford to use the wet 

 pulp. It is worth not ovit $2 a ton on tlie farm.
