Alfalfa is a deep-rooted, perennial flowering plant in the legume family, widely known for its use as a high-protein forage crop for livestock.Cultivated primarily for hay, silage, or grazing, alfalfa is prized for its high nutritional value—rich in protein, fiber, vitamins, and minerals—making it a staple in animal feed, particularly for dairy cattle and horses. It can be harvested multiple times a year, depending on climate and growing conditions.
