A strictly pasturage scheme is to sow wheat or
barley and turn the hogs on this, so that they will eat within certain
prescribed limits. In order to do this, the field needs a shifting
fence, so that the hogs can be driven from one section to another -
never letting the hogs eat too closely, as they will kill off the stand.
Size of a Silo.
I am planning to build a silo 8 feet high and 10 feet across. Will
ensilage (corn, oats) keep well in a silo of those dimensions?
The silo you are intending to build is too shallow, and would hold only
a very small amount of silage. There would be several inches loss of
silage before you could start feeding, and you would have to feed at
least two and probably three inches off per day in order to keep the
food from spoiling. Sixty inches of silage would thus only last about
twenty days. Also, the deeper a silo is, the tighter the ensilage is
packed and the more will be contained in a cubic foot. The following
table will give suggestions as to dimensions:
Diameter. Height. Capacity. Diameter. Height. Capacity.
10 feet 25 feet 36 tons 14 feet 34 feet 115 tons
10 " 28 " 42 " 15 " 34 " 131 "
11 " 29 " 60 " 16 " 35 " 158 "
12 " 32 " 73 " 20 " 35 " 258 "
13 " 33 " 83 "
A cow can consume four tons of silage in 180 days and more or less as
you care to feed, so by figuring out how long you will probably feed,
you can see the size of silo to build at once.
