18 —Lancaster Farming, Saturday. March 4, 1972 New Acids Preservation and storage of high moisture corn with naturally-occurring acetic and propionic acids is a new and efficient method of feeding livestock, scientists report at Pennsylvania State University. Until now, artificial drying or storage in air-tight containers has been essential to avoid spoilage in shelled and ground corn averaging 25 per cent moisture content. Such preservation with mix tures of acetic and propionic acids increases the feed ef ficiency of corn fed to beef cattle and sheep, according to Dr. L. L. Wilson and Dr. T. A. Long of the Department of Animal Science at Penn State. In studies just completed, they also found that the cost per bushel of treating the grain is similar, or slightly higher, than the cost of drying field-shelled corn. The new process sprays shelled ground corn with mix- iheOldlymM.

In the Penn State ex periments, acid-treated corn was placed on a barn floor. There was no spoilage observed in either acid-treated corn or sorghum. Such grains are normally harvested when the moisture content is about 25 per cent and then are dried to 14 per cent moisture. Some air-tight storage is used to prevent spoilage of such high-moisture grains.

More protein was digested and retained in the lambs’ bodies when the animals were fed acid treated, high-moisture corn than when fed ensiled, high-moisture corn without acid. The ration contained 30 per cent ground hay and 70 per cent ground corn. In a study comparing steers fed the dried shelled corn versus the acid-treated, high-moisture corn, feed efficiency was increased nearly five percent with acid treatment. The cattle ate about two per cent more acid-treated grain dry matter than the dried shelled corn.

This decreased feed efficiency may have resulted from moisture content of the grain rather than from acid treatment, the scientists point out. Certain precautions are necessary in handling and storing acid treated corn. The acids, particularly acetic, are corrosive. Metal or concrete storage facilities should be protected with plastic linings. Combinations of acetic and propionic acids are available commercially, and an applicator is also on the market.
