Your grain bins may have suffered irreparable harm if they contained grain that was soaked with floodwater says Hurburgh:
• Sheared bolts
• Elongated bolt holes
• Stretched caulking seals
• Doors misaligned
• Misshapen stirring equipment
• Foundation shifts
• Deteriorated wiring and electronic controls for drying equipment.
So what do you do with the grain that was in contact by floodwater? If the FDA will provide permission, it can be dried and sold, fed immediately, ensiled, but again, only with FDA permission. Wet corn can replace wet corn in the animals’ current ration, with adjustments for moisture. Wet beans can be fed to cattle within 10% to 12% of the ration’s dry matter. Beans do not need to be heat treated before being fed to cattle, but whole raw beans can only be fed to mature sows. They must be heat treated before being fed to finishing hogs.
The bottom line is that Hurburgh says the flooding of 2011 is not likely to create conditions where grain is salvageable.
Floodwaters in many parts of the Cornbelt have damaged stored grain, which means it is likely not salvageable for either food or feed use. To recondition grain, it must not have been in contact with contaminated water and requires FDA approval. Flood damaged grain can also damage grain bins from swelling.
