On a dairy farm they used these silo's to stack the cows in there when it was time to milk them.
No, not really. These silo's were used to store forage for beef and dairy cattle. Haylage which
is chopped alfalfa or corn silage which is chopped corn stalks was blown up into the top of these silo's with
a machine called a silo blower. The silage would ferment and make a tasty treat for the animals. Wood boards
were added to cover the open space on the side as it was filled and these were removed as the silage was taken
out to feed the animals. In the old days the silage had to be hand pitched out to feed the animals. Later on silage
unloaders with electric motors were available to unload the silo's to feed the animals. Normally a tin chute would
cover the opening on the side which would allow the silage to be thrown down that chute to feed the animals. Also,
all silo's had a roof to keep the weather out.
When the silo was in the process of being filled you had to be careful and never climb up into the silo without first blowing
fresh air into the silo with the silo blower. The gases from the fermenting silage would overcome you and kill you. In fact
we had a neighbor lost three of his dairy cows when he turned on the silo blower to blow fresh air into the silo and the gases
came down the silo chute and killed three of his cows close to that silo chute.
More than you really wanted to know, but I could not resist-I still like the first sentence.
