Low-moisture silage (35 to 55 percent moisture). Grass and legume crops are cut and wilted in the field to a lower moisture level than normal for grass silage, but the crop is not sufficiently dry for baling. It is commonly stored in a sealed, or airtight, storage system.

Silage made from hay or grass, often referred to as "grass silage".

Medium moisture silage of 40 to 60% moisture conserved by controlled fermentation in near anaerobic (oxygen limited) conditions.

Ensiled forage crop about 50% dry matter.

Product resulting from ensiling forage with about 45% moisture in the absence of oxygen.

Pasture or crop material that is dried to about 50% moisture content and is preserved for feeding to animals. Usually the air has been evacuated forcefully, as in an airtight, glass-lined silo, rather than by compression of the stack.
