once there was a slight increase in cost and in one instance little 

 change. There was an increase in the yield of milk in six instances 

 (twice the increase was slight) and in three instances a slight de- 

 crease, less than the normal. 



When the change was from a ration containing corn silage to one 

 containing less silage or not any, there followed an increase in the 

 cost of milk in fonr instances and little change once. There was a 

 decrease in the milk yield in fonr instances (once small — less than 

 normal) and little change in one instance. 



When corn silage replaced some other food in the ration or the 

 amount of silage was increased there followed a decrease in the cost 

 of fat in six instances (once but little), a slight increase in cost 

 twice and little change in one instance. There was an increase in 

 the amount of fat in five instances (three times slight), little change 

 in amount three times, and a small decrease once. 



When the change was from a ration containing corn silage to one 

 containing less or not any, there followed an increase in the cost of 

 fat in five instances (in three of them the increase was small). 

 There was a decrease in the amount of fat in three instances and 

 little change in amount twice. 



When the change in the ration was to more silage or to silage in 

 place of some other food there followed an increase in the per cent, 

 of fat in the milk in six instances, (three times the increase was 

 slight), a decrease in two instances and little change once. 



After a change from a ration containing corn silage to one con- 

 taining less silage or not any, there followed a decrease in the per 

 cent, of fat in the milk in two instances, an increase in two in- 

 stances (one of them slight), and little change once. 



In general there has been an increase in milk flow accom- 

 panying the use of corn silage in the ration and at the same time an 

 increase in the amount of fat, the per cent, of fat not diminishing. 

 At the valuations for foods given on page 39-i milk has very gen- 

 erally been produced at lower cost and the cost of the production of 

 fat has been lower while corn silage has constituted part of the 

 ration. 



Miscellaneous Feeding Trials. 



Besides those feeding trials just considered in which the results 

 accompanying the use of corn silage are especially noticed, it is 

 thought well to also report at this time the results obtained in sev-
