Alfahay comes in a 50 pound bag and is the closest thing to fresh cut alfalfa. Alfahay is a NON-GMO alfalfa. Alfahay is for horses, cattle, pigs, deer, goats, sheep, birds, and exotics. Unlike other feeds that are dried, Alfahay is cut and packed with its natural moisture. This locks in all the fresh nutrition of the plant. Alfahay then undergoes a fermentation process after being bagged to produce beneficial yeasts and bacteria. That's why we call it "Probiotic Alfalfa In A Bag"
