High Quality Content by WIKIPEDIA articles! Silage is fermented, high-moisture fodder that can be fed to ruminants (cud-chewing animals like cattle and sheep) or used as a biofuel feedstock for anaerobic digesters. It is fermented and stored in a process called ensiling or silaging, and is usually made from grass crops, including corn (maize), sorghum or other cereals, using the entire green plant (not just the grain). Silage can be made from many field crops, and special terms may be used depending on type (oatlage for oats, haylage for alfalfa – but see below for the different British use of the term haylage).
