good feeding a possibility the year round. 



6. It permits the storage of a large amount of feed in 

 a comparatively small space. 



7. Where the silo adjoins the barn it makes feeding 

 easy. 



8. It permits housing the corn crop regardless of the 

 condition of the weather. 



9. There is practically no waste in feeding. 



10. It yields the largest amount of feed possible from 

 the corn plant. 



Size of Silo. The size of the silo is determined by 

 the number of cattle to be fed. In general, a cow will 

 consume about 40 pounds of silage daily ; and, if fed 

 silage 1 80 days in the year, she will consume a total of 

 7,200 pounds. At this rate 20 head of cattle would con- 

 sume 72 tons. But it should be remembered that it re- 

 quires a silo of not less than 80 tons' capacity to hold 

 72 tons of well made silage. A cylindrical silo of this 

 capacity will measure about 14 feet in diameter and 28 

 feet in height. (See appendix.) 



A good rule to follow in determining the size of a silo 

 is to estimate the amount of silage that is to be fed dur- 

 ing the year and assume a weight of 40 pounds for every 

 cubic foot of silage. 



Silos should not be built too large. Where 150 to 200 

 tons of silage are required, it is far better to put this 

 amount of silage into two silos than into one. The height 

 of the silo should be limited to thirty feet. Too much 

 power is required in elevating the silage higher than 

 this and those who have climbed high silos will be able to 

 testify to the fact that it is not an agreeable task. 



Where a silo is built with a reasonable capacity, it is
