Grass hay is a type of forage made from dried grasses, commonly used as animal feed. It is harvested at a specific time to ensure optimal nutritional value, typically before the grasses go to seed. Grass hay is rich in fiber, which is essential for the digestive health of herbivores like horses, cattle, and rabbits. There are various types of grass hay, including timothy, orchard grass, and brome grass. Each type has different nutritional profiles and palatability, making it important for animal owners to choose the right kind for their livestock. Proper storage is crucial to prevent spoilage and maintain quality.
