42 AGRICULTURAL EXPERIMENT STATION. [Jan. 



feed constituents used, ranks first mixed ensilage and rowen 

 (periods IV., V.), then rowen (I., II., III., VIII. , IX.) 

 and dry corn stover last (VI., VII.), as far as the daily 

 yield of milk is concerned. 



The difference noticeable in the daily average yield of 

 milk in case of rowen, as compared with corn stover, does 

 in no instance deprive the latter of the claim to be the 

 cheaper coarse fodder article of the two in our trial. Mixed 

 ensilage, with rowen in place of corn stover, on the other 

 hand, has raised in some instances the daily yield of milk 

 more than three quarts (Pearl and Buttercup); allowing 

 three cents per quart of milk makes the former the cheaper 

 coarse fodder article of the two, under otherwise corre- 

 sponding circumstances. These results are noticeable with- 

 out reference to the particular combination of grain feed 

 rations used in either case. 



The influence of the various grain feed rations on the 

 yield of milk in case of the same kind of coarse fodder 

 ration is apparently, to a considerable degree, depending on 

 the individual disposition of the animal on trial. Cotton- 

 seed meal containing grain feed rations give in five out of 

 six cases better results when fed with rowen than either 

 gluten meal or old-process linseed meal ration, under other- 

 wise corresponding conditions. Gluten meal and cotton-seed 

 meal did equally well when fed with either mixed ensilage 

 or corn stover. Old-process linseed meal has only been fed 

 with rowen on the present occasion (I., II., III.) ; it com- 

 pared well in yield of milk with gluten meal.
