What are all the types of hay?

There are several types of hay, primarily categorized by the type of grass or legume used. Common types include alfalfa hay, which is high in protein; timothy hay, favored for its fiber content; and orchard grass hay, known for its palatability. Other types include clover hay, mixed grass hay, and oat hay, each offering different nutritional benefits for livestock and other animals. The selection often depends on the specific dietary needs of the animals being fed.
