Chaff is the seed casings and other parts inedible to humans of plant matter harvested with cereal grains such as wheat. The chaff must be separated from the grain before use, by such techniques as threshing and wind winnowing. The word "Chaff" is also used to refer to something worthless, such as in the expression "separating the wheat from the chaff", meaning to find things of value and separate them from things of no value.

A horse and cattle feed

If hay, or less often straw, is cut into very short lengths by a specially designed machine (called a chaff cutter), and fed to horses or cattle it is called chaff. It can be fed to horses which have problems with their wind (breathing) to reduce the amount of dust they breath in while eating hay.
