State station. Two rations were compounded hav- 

 ing practically the same composition, yet differing

Aside from the standpoint of economy, another 

 object of this test was to determine whether silage 

 could be made to take the place of a considerable 

 portion of the grain usually fed to dairy cows. The 

 silage used was a mixture of one ton of soy beans 

 and cow peas to two and one-half tons of silage corn. 

 The two rations, as shown above, contained about 

 the same amount of nutrients. The cost of the 

 silage ration, however, averaged 13.48 cents daily,
