of each day. So the fertilizer vahie of the excrement recovered during 

 these trials will fairly represent the average value recovered from the 

 university herd during the winter months, when the cows are fed a 

 hay and grain ration similar to those given in the preceding table. 



In comparing this ration with rations fed on farms throughout the 

 State, it must be borne in mind that these cows were large, averaging 

 nearly 1,125 pounds per .head, and that it would be better to make the 

 comparison per 1,000 pounds live weight rather than per head. 



It is for each farmer to determine for himself whether he supplies 

 his cows with an amount of plant food equal to that fed the university 

 herd before the results of these trials are to be applied direct to his 

 own herd. It must be borne in mind that in all of these trials nearly 

 all of the cows were giving milk and would average about the middle 

 of the milking period. 



The following tables give the amount of dry matter consumed and 

 the amount and value of excrement recovered. 



Per 1,000 Pounds Live Weight of Animal Per Day. 



Recovered From 1.000 Pounds of Animal Per Day.
