Feeds and Feeding. 



409. Capacity of silos. — The following table by the same author 

 gives the capacity of round silos at different depths and varying 

 inside diameters: 



Approximate capacity of cylindrical sUosfor well-matured corn silage, 

 in tons — King. 



In the above table the horizontal lines give the number of tons 

 held by silos of the diameter marked at the top of the columns 

 and depth marked at the side. 



410. The proper horizontal feeding area. — Silage cannot be cut 

 down in sections like hay in the mow or stack, as tlie air passing 

 inward and upward would rapidly deteriorate the whole mass. 

 The proper method is to remove a certain portion of the silage 

 from the top of the pit each day, and experience has shown 

 that the rate of removal should be not less than 1.2 inches per 

 day. Every two inches in depth of corn silage weighs about five 

 pounds per square foot near the top of the silo and ten pounds 

 near the bottom, averaging about seven and a half pounds. On 

 this basis the proper surface area may be placed at five square 

 feet per cow, daily. As a guide for the proper surface area of 

 the silo. King gives the following table, showing the inside diam- 

 eter of silos which will allow the silage to be fed down at the 

 rate of two or three inches a day when each cow is allowed forty
