and thereby have more nutriment available for milk or flesh produc-

351. Yield of silage corn and roots. Since corn silage and roots 

 are both succulent and equally relished by stock, the choice between 

 them will, in many cases, finally turn upon the cost of production and 

 the amount of nutriment yielded by each crop on a given area of 

 land. The following table from Woll 1 and the Pennsylvania Sta- 

 tion 2 shows the green substance and dry matter yielded by an acre 

 of fodder corn and roots, grown under the same conditions at 4 sta- 

 tions : 



Yield of fresh and dry matter per acre of roots and fodder corn. 



It is shown that crops of corn yield about twice as much dry mat- 

 ter as do crops of roots grown on similar land. 



352. Dry matter in roots and silage. The value of the dry mat- 

 ter in roots and silage for milk production has been studied at the 

 Ohio, 3 Pennsylvania,* and Vermont 5 Stations with the following re- 

 sults : 



Milk from 100 Ibs. of dry matter in corn silage and ~beet rations. 



It will be seen that, altho practically all of the dry matter in beets 

 is digestible and only a part of that in corn silage, dairy cows gave 

 somewhat better returns on the dry matter of silage than on that in 

 the beet ration.
