Tests with Feeding Stuff's. 407 



ing, the crop from 12 acres, averaging 11.25 tons of green forage, 

 was run thru the feed cutter and placed in the silo. The remaining 

 '6 acres was harvested by cutting and shocking. After curing in the 

 field for a month, the unhusked fodder, yielding 4.1 tons per acre, 

 was stored in the barn. The cost of ensiling the crop was $11.22 per 

 acre, while cutting, shocking, storing the unhusked fodder in the 

 barn, and later running it thru the feed cutter cost $10.31 per acre. 

 The next step was to test the relative merits of the silage and 

 fodder. Two lots of 4 cows each were fed silage and fodder corn, 

 respectively, for 2 twelve-day periods as shown below, the rations 

 being reversed at the close of the first feeding period. The silage 

 was eaten without waste, while a portion of the fodder corn was left 

 uneaten. Both lots of cows gained in weight during the trial. 



Corn silage compared with corn fodder. 



The table shows that the silage-fed cows averaged 2.7 lbs., or 12.8 

 per ct., more milk daily than those on dry fodder corn — a convincing 

 example of the merits of corn silage. 



Hills of the Vermont Station^ found that cows fed green fodder 

 corn early in September shrank 5 per ct. in butter yield, while others 

 fed corn silage pitted the previous year gained 8 per ct. (350) 



655. Corn silage v. hay.— At the Maine Station- Jordan fed cows 

 first with good hay, later with hay and silage, and again with hay, 

 all getting the same amount of concentrates. The yield of 4 cows 

 for 14-day periods, just preceding or following a change in the ra- 

 tion, was as follows : 



When fed on hay 1,212 pounds 



When changed to silage and hay 1,297 pounds 



An increase of 85 lbs., or 7 per ct. 



When fed on silage and hay 1,200 pounds 



When changed to hay 1,098 pounds 



A decrease of 102" lbs., or 8 per ct.
