It's for winter feed. When I was a kid they put just about everything in there, maize, barley, corn, all of it. But then it was in concrete pits.
They fed the cows with self unloading trailers. When the alfalfa was in they'd feed it to them as green feed. You'd have one tractor pulling the cutter-grinder and it'd be shooting the stuff off to the side into a self unloading trailer being pulled by another tractor. When it was full there'd be another ready to move in for it's load.
The farmer had a contract with Farmall. They'd give him tractors to work for testing purposes. I remember the time dad was so proud cause he had what he thought was the first one ever with powersteering.
Winter time they'd fill the self unloading trailers with the silage instead of green feed.
The trailers were pretty neat. They had chutes at the front and the feed was brought forward bya live bottom up to another live bottom running perpendicular to the main one. Then the live bottom feeding off to the side would shoot the feed into the trough. It all worked off the PTO of the tractor.
Most of them were tricycles and they all ran on propane.
My dad worked mixing feed for two dairies, one holstein for milk, and one jersey for cream products and milk. He also did the feed for twenty thousand layers. There were about twelve hundred or so cows in each dairy if I remember right.
One time we had two hundred and fifty head of hereford heifers on the place. The place of course was eighty acres. The man my father worked for over the years had bought up all these small farms. He then provided a roof, salary, and milk for the help.
We also got eggs and occasionally we'd get ten or so wore out hens to butcher. But every night when we went to pick up dad we'd take a big mouth gallon jar and go into the dairy and right from the big stainless tank fill it up, fresh raw milk. If were lucky or unlucky, purely point of perspective, we'd get the little black specs too.
Then there was the time dad messed up and had four forty come in one hand and out the other. He always said he never really had a hairy chest until after that. But he was off work for six weeks or so. Across the street from us was eighty acres or so of watermellon. The old boy that owned it told us to help ourselves. Even the dog and cats got by on watermelon for awhile.
I remember going down to the silage pit. It was a lot more coarse than the stuff Bird was describing. It had big chunks and didn't smell all that good to a kid's nose.
We were so poor that we didn't know it. That's poor.
