It is seen that fodder corn yields about twice the dry matter 

 that can be secured fi-om a crop of roots grown on the same land. 



394. Dry matter in siiage and roots. — The value of the dry 

 matter of roots and silage for milk production has been studied 

 at the Ohio, ' Pennsylvania ^ and Vermont* Stations with the fol- 

 lowing results: 



MUh produced by feeding one hundred pounds of dry matter in com 

 silage and beet rations — Three Stations. 



It will be seen that although practically all of the dry matter 

 of beets is digestible, while a considerable portion of that in com 

 silage is not, dairy cows, when fed rations consisting largely of
