50 AGRICULTURAL EXPERIMENT STATION. [Jan. 



cow. The amount actually consumed per day varied in 

 case of vetch and oats from 30 to 55 pounds ; of cow-pea., 

 from 66 to 84 pounds ; and, in case of serradella, from 63 to 

 85 pounds ; showing luit little preference for one as compared 

 with the others. The difference in the daily consumption 

 of the green fodders was due largely to their variations in 

 dry vegetable matter during the progress of the experiment. 

 The experiment was sub-divided into live feeding periods, 

 beginning and ending with a hay fodder ration. The daily 

 waste of coarse feed amounted per head to four pounds in 

 case of oats and vetch, to two pounds in case of serradella, 

 to one and one-half pounds in case of cow-pea ; and, in case 

 of hay, to one-half pound. 



The results obtained fully sustain the conclusions pre- 

 sented in our previous reports, namely : — 



1. The weight of dry vegetable matter contained in the 

 feed consumed for the production of one quart of milk is 

 less in case of the green fodder rations than in the hay 

 ration ; indicating a superior nutritive value of the former, 

 as compared with the latter. 



2. The yield of milk is in every instance increased, 

 when changing from a hay ration to a green fodder ration. 



3. The quality of milk is but slightly altered in case of 

 different cows ; the solids in some instances are slightly 

 increased, in others they are slightly decreased. The 

 creamery record, as will l)e seen from subsequent ab- 

 stracts, is very satisfactory in case of the green fodder 

 rations. 



4. The net cost of feed for the production of milk is in 

 every instance less in case of green fodder rations than in 

 the hay ration. 



5. The weight of the animal has in most instances in- 

 creased towards the close of the experiment.
