CONCLUSIONS DRAWN FROM THE FOREGOING DATA. 



This experiment, although too limited to be of much value 

 in itself, confirms the results of Professor Robertson's investi- 

 gations and those obtained from experiments made at this 

 Station last year, showing that silage, of the quality used, can 

 be substituted in part for the grain ration of milch cows without 

 causing loss of flesh or lessening the production of milk. 



In this case fifteen pounds of silage appeared to equal four 

 pounds of the grain mixture. 



GROUND OATS COMPARED WITH WHEAT BRAN FOR MILCH 



COWS. 



In some sections of the State oats are a very important crop 

 and are extensively grown for market or feeding to animals. 

 When the price is so low that it hardly pays to take them to 

 market in exchange for other grains, the station receives fre- 

 quent inquiries as to their value as feed for milch cows.
