Silage is a type of feed for livestock that is made by fermenting and preserving high-moisture crops such as grass, corn, or alfalfa. It is typically used as a winter feed for cattle, sheep, and other ruminant animals. Silage is made by chopping the crop into small pieces, packing it tightly into a storage structure called a silo, and then sealing it to create an anaerobic (oxygen-free) environment. The lack of oxygen allows beneficial bacteria to ferment the crop, converting sugars into organic acids, which helps preserve the feed and improve its nutritional value. Silage is a valuable source of energy, protein, and fiber for livestock, and it helps farmers ensure a consistent and nutritious feed supply throughout the year.
