What’s the difference between straw and hay?

Straw is the dry stalk of a cereal plant (like wheat, flax, oats, rye, rice, or barely) after the nutrient grain or seed has been removed. It’s the material that is left over once the combine harvester has removed the more valuable tops of the plant. Hay is grass or legumes that have been cut, dried, stored to be used for animal feed. It is generally fed when there is a shortage of pasture or rangeland on which to graze animals, and especially during winter months.
