Alfalfa is in the same plant family as peas, beans and clover. Alfalfa has been cultivated for fodder for horses for over 2000 years originating from Iran and then spreading across the world as Persians, Greeks and Romans expanded their empires and took their horses and their feed with them. There is a reason alfalfa is still used for feeding to horses today and that's because it is safe and nutritious. | Wyoming Hay Cubes Alfalfa Cubes | Size 50 lbs
