Beet pulp
Beet pulp is a byproduct from the processing of sugar beet which is used as fodder for horses and other livestock. Beet pulp is the fibrous material left over after the sugar is extracted from sugar beets. It is supplied either as dried flakes or as compressed pellets, but when fed to horses it is usually soaked in water first.
