I have a whole bunch of pictures and videos from combing corn, so I will break this up into a couple posts.
I will start out with grinding high moisture corn. For this process we want the corn to be between 25% and 30% moisture. As opposed to dry corn which we combine as dry as we can, and then use a drier to take it down to 15% for storage.
We run the corn through a hammer mill, which grinds it very fine. Then we push it into a bunker and cover it just like silage. It goes through a similar fermentation process to preserve itself as silage does. We do add an inoculate to help the process along.
It is a very boring job watching the grinder. We spend several days grinding approximately 15,000 bushels.
Both the grinding and fermentation process help to break down the corn so that the cow can more completely digest it, and fully utilize it to produce yummy milk! If it isn’t ground fine, it just comes out the back end of the cow, and that doesn’t do us any good! 🙂
And last but not least, a little video of the grinder in action. Now watch this video for hours and hours to get a TRUE feel for what grinding corn is like. Oh, and cover yourself in flour to get a taste of some dust as well. 🙂
