492 FARM AND SCHOOL PROBLEMS. 



13. Silage keeps better in a deep silo than in a shallow one, for it 

 must be firmly packed. 



14. The height of the silo should be at least twice the diameter. 



15. It may be assumed that 40 pounds per day will be required to 

 feed each head of cattle. 



Silage bears about the same relation to fresb corn that 

 canned corn bears to fresh ears. 



Silage has about the same effects on stock in winter that 

 pasture has on animals in summer. An animal fed on silage is 

 rarely troubled with constipation or poor digestion. The hair is 

 noticeably sleek and soft and the skin is soft and pliable. The 

 amount of ensilage to be fed will depend upon the mixed ration 

 that is selected, and upon the amount of milk given by the cow 

 as well as upon her size and physical condition. 



PROBLEMS. 



1. Experiences have proven that in feeding corn in the form of 

 ensilage, 35 per cent of the value of the corn is in the stalk and leaves; 

 if the corn stover on ten acres of corn at 3c per bundle will amount to 

 $45, what would it have been worth as ensilage, valued at 100 per cent 

 more than stover? 



2. If the stalks and leaves of corn will take up 10 times as much 

 space in the form of fodder as in the form of ensilage, how large a sila 

 (in cu. ft.) will hold, as ensilage, the stalks and leaves which in the 

 form of dry fodder compactly stored, will occupy space in a mow 15x20x40 

 feet? 



When silage is left exposed to the air for more than a day 

 it will spoil. It has been found by experience that it is a good 

 practice to remove at least two inches from the surface each day. 



The amount which should be fed daily should be based upon 

 an average weight of forty pounds per cubic foot. 



PROBLEMS. 



1. If the weight of ensilage in a silo was found to be 40 pounds per 

 cubic foot, how many pounds must be removed to lower the surface 3 

 inches in a silo that is 12 feet in diameter? 



2. A dairyman wishes to construct a silo from which he expects to 

 feed 12 cows. If the average amount of silage to be fed per cow is 3ft
