The Horizontal Feeding Area. — Silage must be removed from 

 the top and not sliced or cut down vertically as is often practiced 

 in feeding hay from the mow or stack, because the entrance of 

 air will rapidly spoil it. It is considered that at least 1.2 inches 

 should be removed per day from the top to prevent molding. 

 Two inches of corn silage weigh 5 lbs. per square foot at the 

 top and ID lbs. at the bottom, or an average of 7.5 lbs. for the 

 silo. The daily requirement for a cow, at this rate, would be 

 about 5 square feet surface area. The feeding area should not 

 be so large that enough cannot be fed per day to prevent 

 deterioration.
