Milo is a grain that comes from the sorghum plant, Sorghum bicolor. It is also known as grain sorghum, and is used for a variety of purposes, including food for humans, animal feed, ethanol production, and as a summer forage crop. Milo is a high-energy grain that is often fed to horses, and is a good source of protein, fiber, antioxidants, B vitamins, phosphorous, copper, manganese, and iron. It is gluten-free and easy to grow in hot, dry climates. Milo is also used in flour making, bioenergy production, packing peanuts manufacturing, mushroom cultivation, and as a healthy sweetener and high-quality aquatic feed. Large reddish milo seed is commonly used as a filler in birdseed. Milo contains a large percentage of digestible nutrients that are similar to mid-quality hay, and is often substituted for cracked corn. Farmers may choose to add a protein supplement to the cattleās diet when feeding them milo.
