Haylage, also known as baleage, is a term for silage made specifically from grass crops. Fermented feedstuffs can be stored in silos, towers, clamps, and wrapped bales. However, storage methods that allow the edges of the silage to be exposed to open air may experience some waste due to spoilage. Many farmers prepare their own hay and silage, but it can also be purchased from dedicated feed producers. Silage is often more cost-effective than hay, and it has the added benefit of not being damaged by rainfall.
