(i) Comparison of dry matter in silage and in mangels 

 A number of experiments comparing the feeding value of silage and 



mangels have been conducted at the agricultural experiment stations 



in the United States. 



At the Ohio Station Thorne, Hickman and Falkenbach* seem to have 



conducted the most extensive experiments recorded in the literature 



of the stations. These continued from 1889 to 1892, with the general 



results as follows: 



(i) The feeding of beets to milk cows increased the consumption 



of other foods and of total dry matter.
