340 results about "Silage" patented technology

Silage is a type of fodder made from green foliage crops which have been preserved by acidification, achieved through fermentation. It can be fed to cattle, sheep and other such ruminants (cud-chewing animals). The fermentation and storage process is called ensilage, ensiling or silaging, and is usually made from grass crops, including 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.
