Hay balls, also known as hay bales, are cylindrical or rectangular bundles of dried grass or legumes, typically used as animal feed. They are created by compressing cut and dried plants into tight shapes, making them easier to store and transport. Hay balls are commonly used in agriculture to provide nutrition for livestock such as cows, horses, and sheep during the winter months when fresh grass is not available. The process of making hay balls involves cutting the grass at the right time, allowing it to dry, and then using a baler machine to compress the material. Once formed, hay balls can be wrapped in plastic or twine to protect them from moisture and pests. Properly stored hay balls can last for several months, ensuring that animals have access to food even when pasture is scarce.
