Silage

Silage is fodder made from green foliage crops which have been preserved by fermentation to the point of souring. It is fed to cattle, sheep, and other ruminants. The fermentation and storage process is called ensilage, ensiling, or silaging. The exact methods vary, depending on available technology, local tradition, and prevailing climate.

Silage is usually made from grass crops including maize, rye, sorghum, or other cereals, using the entire green plant (not just the grain). Specific terms may be used for silage made from particular crops, such as oatlage for oats and haylage for alfalfa (haylage may also refer to high dry-matter silage made from hay).
