FEEDING EXPERIMENTS WITH MELCH COWS. 



1. COMPARATIVE VALUE OF DIFFERENT COARSE 



FEEDS. 



By J. B. LiNDSEY. 

 October-December, 1893. 



[Grains fed: wheat bran, Buffalo gluten feed, new-process linseed meal. Coarse 

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



Object of the Experiment. 



To note the comparative eftect of English hay, dry vetch 

 and oats, soja-bean hay and barley straw upon the produc- 

 tion and cost of milk. 



Results of the Experiment. 



The average cost of producing milk from six cows of the 

 station herd in different periods of lactation was 2.3 cents 

 per quart; the average yield was 9.46 quarts per day. 



Hay of vetch and oats compared very favorably with 

 English hay for milk production. 



The conq>osition of the milk was apparently not affected 

 by the different coarse fodders. 



The Experiment. 



The analyses of the foods fed and their fertilizing value, 

 the history and feeding record of the individual cows, etc., 

 will be found at the end of the experiment. 



Six cows were used in the trial; they were grades of 

 various breeds in different jieriods of lactation, yielding from 

 7 to 15 quarts of milk daily.
