condition of cows, at the same time reducing tlie net cost of the feed consumed 

 and furnishing vahiable homemade manure at the lowest market cost. The 

 European standard for a daily diet of milch cows calls for one part of digestible 

 nitrogenous fodder constituents to live and four-tenths parts of digestible non- 

 nitrogenous food constituents. Our results on the whole point in the same 

 direction. The nitrogenous food constituents of the fodder rations received 

 special attention. 



In the experiment reported in this bulletin the main subject of 

 inquiry related to the etfect of the partial or com])lete substitution of 

 corn fodder, corn stover, or corn silage for English ha}^ on the net 

 cost of the feed and the quality and quantity of milk produced. 



The percentage of solids and fat in the milk and cream produced 

 during ditferent periods in 1888 and 1889, and the average number of 

 quarts of milk required to make one space of cream during dift'erent 

 periods are given in tables. 



Conclusions. — From the financial standpoint it is shown that wher- 

 ever fodder corn, corn stover, or corn silage were fed as a complete or 

 partial substitute for English hay. in connection with a stated grain 

 ration, the commercial value of the manure obtainable Avas aftected 

 slightly if at all. while the net cost of the daily feed was reduced from 

 one-third to one-half. 



" The partial abstracts from the milk and creamery records show 

 that the fodder corn, corn stover, and corn silage, Avhen fed pound for 

 pound of dry matter in place of English hay. compare well as far as 

 the quality and the quantity of the milk and of the cream obtained is 

 concerned. 



'' There can be no doubt about the fact, in the jjresent condition of 

 our market prices of feed stuffs, that the care and the expense 

 required to secure a well-cured corn fodder and corn stover or a well- 

 prepared corn silage, as circumstances may advise, and to offer them 

 in an acceptal)le form to niilcli cows will ])rove a paying investment. 



" It may not be without interest to state here that the results of 

 feeding experiments of a similar character, of late published by the 

 Ohio and Iowa Experiment Stations, coincide in the main with ours 

 stated in previous reports."
