Corn cobs can be fed to cattle as forage, but these have to be treated with a chemical to make them more digestible.

A research conducted at the University of Nebraska in USA showed that crossbred steers (young male cattles) fed with corn cobs treated with calcium hydroxide gained twice as much weight as those fed with untreated cobs.

American cattle raisers have been feeding treated corn cobs to their animals.

The commonly-used chemical, however, is sodium hydroxide, which can leave a residue that is potentially harmful to soil, animals and humans.

Calcium hydroxide, on the other hand, is safer and cheaper to use in treating corn cobs as cattle feed.
