CHAPTER XX. 

 THE SILO. 



How LARGE TO BUILD. 



A FULL-GROWN cow will consume from one and one- 

 half to two cubic feet of ensilage per day, but gen- 

 erally it has been found advisable to make one of 

 three feedings a day of hay. 



At one and one-half cubic feet per day, a cow 

 would consume in six months (the usual length of 

 time for feeding winter forage in Western New 

 York), 270 cubic feet, allowing for waste, say 300 

 cubic feet. If we multiply 300 cubic feet by the 

 number of animals we wish to feed, it will give 

 the size that is required to build, in cubic feet. 



The following table gives the capacity in tons of 

 different-sized silos. It is reckoned at forty cubic 

 feet per ton, and a ton to last a cow one month. 

 That is about sixty-six pounds per day, which is a 

 liberal feeding. The quantity is computed for six 

 months, estimating fifteen tons per acre.
