Cost of the acid is around 10 to 16 cents a bushel. Metal bins should be lined with plastic or coated with an acid-resistant paint to prevent corrosion from the acid. Concrete bins or silos should be lined with plastic to prevent mold developing in grain near the concrete surface. Place a black polyethylene cover over the top of grain in an open bunk to protect it from the weather. Supplements Sorghum grain rations need supplementation for beef cattle similar to that used with corn rations.
Grains are adequate, or nearly so, in phosphorus but deficient in calcium for cattle.
Potassium and certain trace minerals may be deficient in sorghum grain rations that contain little roughage unless alfalfa or other good quality legumes are used for the limited roughage. Vitamin A will need to be added. Scientists at Arizona State University have found steamflaked milo rations that included 40 percent roughage in the first part of the feeding program to be followed by 20 percent or 10 percent roughage in the latter part worked well for yearling cattle with 600-pound starting weights. The roughage has been composed of ground alfalfa hay or cottonseed hulls or equal parts of each. They usually include 5 percent molasses and 4 percent fat in the ration to decrease dustiness and increase energy.
