FEEDS. 



By J. B. LiNUSEY. 



October-December, 1893. 



[Grains fed : wlieat bran, Buffalo gluten feed, new-process linseed meal, ('oarse 

 feeds : hay, dry vetch and oats, soja-bean hay and barley straw.]

 station herd in different periods of lactation was 2.3 cents 

 per quart; the average yield was 9.4G <]uarts i)er day. 



Hay of vetch and oats compared very favorably Avith 

 English hay for milk production. 



The com[>ositi()n of the milk was a})parently not affected 

 by the dilfcrcnt coarse fodders. 



The Expertmknt.
