P^ESDING EXPERI:MENTS with MILCK cows, C. A. GOESSMANX, Ph. 



D. (pp. 2-12). — This is a summary of feeding experiments begun at 

 the Station in November, 1885, with special reference to those con- 

 ducted in 1889. More detailed accounts of the earlier experiments 

 will ]je found in the annual reports and bulletins of the Station pre- 

 viously published. The object of these experiments was to get infor- 

 mation on the following points : 



(1) The total and net cost of the daily ration per head with the dif- 

 ferent combinations of feeding stuffs used. The net cost was esti- 

 mated by assuming that 20 per cent of the fertilizing ingredients of 

 the food would be sold witli the milk, assigning a manurial value to 

 the remaining 80 per cent supposed to be saved, and subtracting the 

 value of manure comj)uted on this basis from the total cost of food. 



(2) The connnercial value (on the assumption above stated), at 

 current market rates, for nitrogen, phosphoric acid, and ])otash, of 

 the manure from tlie different combinations of feeding stuff's used, 

 which can be secured to the farm by careful management. 



(3) The comparative feeding value of dry fodder corn, dry corn 

 stover, and corn silage as complete or partial substitutes for English 

 hay (ui)land meadow hay) in the daily diet of milch cows; and also 

 of a good root crop as a sul)stitute for corn silage. 



As indicated iu a tabular sunmiary. the experiments were divided 

 into four series : 



Series 1: With two cows, from November 20, 1885. to flulv 1, 1880,
