packed down at the top. The spoiled layer must be thrown away and 
should never be brought near the barn, but should be dumped into 
the manure pit or else put into the manure spreader and carted off 
immediately to the fields, as the odor is disagreeable and the spoiled 
material is unfit for feed. 
One tall, narrow silo is better than two short, wide ones; first, because 
there is only one top layer to spoil, and second, because shrinkage in the 
tall silo is little, if any, more than that of either of the two smaller. It 
is known that a silo 14 x 60 feet will have approximately twice the capacity 
of a silo 14 X 40 feet. This is because the silage in the tall, narrow silo 
is better compacted. Not only is there a saving because of only one top 
layer and a smaller percentage of shrinkage, but the silage in the bottom 
40 feet of the tall silo is generally superior and more valuable because the 
air has been so completely excluded. 
At least 2 inches each day must be fed off the entire top of the silo 
in order to prevent mold. Some authorities advise that the surface of 
the silage be kept level, but in the Northern States, it is customary to 
make the surface cone-shaped to prevent freezing around the edges. 
Frozen silage should never be fed and can be best thawed out after 
the day's feed is thrown down the chute by scraping it from the walls 
and piling it in the center of the silo to thaw out. 
Only as much silage should be thrown down the chute at one time, 
as is required at that specific feeding period. Otherwise, the silage will 
spoil and the feeder can blame only his own carelessness.
