Hay is a type of forage consisting of grass, legumes, or other herbaceous plants that have been cut and dried. This process allows the vegetation to be stored for later use as animal fodder.
The primary purpose of hay is to provide nutrition for livestock, including large grazing animals such as cattle, horses, goats, and sheep. It is also used as feed for smaller domesticated animals like rabbits and guinea pigs. While pigs can consume hay, they do not digest it as efficiently as herbivorous animals.
