2OO ELEMENTARY TREATISE ON STOCK FEEDS AND FEEDING 



The table 1 which follows gives the diameters and depths of 

 silos of two types which hold enough silage for 180 days, feeding 

 2 or 3.2 inches a day, allowing each cow 40 Ibs. 



This table 2 gives the number of cows in herd and tonnage of 

 silage for both 180 and 240 days of feeding of 40 pounds of sil- 

 age per cow, also acreage of corn estimated to fill the silo and 

 the dimensions of the silo itself. The diameters given are such 

 that at least 2 inches in depth of silage will be taken off daily.
