What is grass that is baled and stored for feed commonly known as?

The term that refers to grass which has been cut, dried, and then baled for storage as feed is "hay." Hay is an important feed source for livestock, providing essential nutrients, especially during times when fresh pasture is not available. It is made from various grasses and legumes that are harvested at the right stage of growth for optimal nutritional value.

Silage, on the other hand, is fermented feed made from green foliage crops which are stored in a silo or a pit and tends to have a higher moisture content, making it different from hay. Fodder generally refers to various types of animal feed, including grains and fodder crops, and is not specific to the process of drying and baling grass. Straw is the dried stem of cereal plants such as wheat or barley after the grain has been harvested, and it is typically used for bedding rather than as a primary feed source. Therefore, hay is the most accurate term for this process of preparing grass for animal feed.
