Oxbow Alfalfa Hay is a high-fiber legume hay with the same long-strand fiber found in grass hays, but with more protein, energy and calcium. This hay is perfect for young or lactating animals that need concentrated nutrition. The succulent taste stimulates the appetite of ill or post-surgical animals. Once an animal reaches adulthood or completes recovery, this nutritious forage should be replaced with a grass hay. Alfalfa Hay, mixed with any other Oxbow grass hay, creates a rich, flavorful and nutritious treat. Sizes: 15 oz, 9 lb, 25 lb, 40 lb.
