2. What is the total cost, as well as the net cost, of the 

 daily feed per head in case of the diflereut fodder combina- 

 tions used ; making in all cases alike an allowance of a loss 

 of twenty per cent, of the fertilizing constituents contained 

 in the feed consumed, in consequence of the sale of the 

 milk? 



3. What is the commercial value, at current market 

 rates, of the manurial refuse obtainable in the case of different 

 fodder combinations used as daily diet for the support of cows, 

 assuming that eighty per cent, of the value of the fertilizing 

 constituents contained in the fodder consumed can be secured 

 to the farm by a careful management? 



The results of these experiments, which extend over a 

 period of five successive years, 18b5-89, were summed up 

 in the following statements : — 



1. The high nutritive value of fodder corn, corn stover 

 and good corn ensilage, as compared with that of P^nglish 

 hay, counting in all instances pound for pound of dry vege- 

 table matter, is fully confirmed. The general condition of 

 the animal on trial, as well as the quality and the quantity 

 of the milk obtained, point in that direction. 



2. To produce one quart of milk, using the same quan- 

 tity and quality of grain feed, required in every instance a 

 larger quantity of perfectly dried hay than of either fodder 

 corn, corn stover or corn ensilage, in a corresponding state 

 of dryness, — corn stover leading. 



3. The net cost of feed in the case of the same ration of 

 grain feed is from one-third to one-half less per quart of 

 milk, when fodder corn, corn stover or corn ensilage serve 

 as substitutes for English hay in the daily diet of milch 

 cows ; corn fodder, as a rule, leading, while corn stover 

 leads the corn ensilage in four out of six cases. 



4. Sugar beets, as well as carrots, when fed pound for 

 pound of dry matter in place of part of the hay ration, with 

 the same kind and quantity of grain feed, have raised almost 

 without an exception the temporary yield of milk ; exceed- 

 ing, as a rule, the corn ensilage in that direction. 



5. Corn ensilage, as well as roots, proved best when fed 

 in place of one-fourth to one-half of the full hay ration. 

 From twenty-five to twenty-seven pounds of roots, or from
