The red bean grass has high yield, good palatability, easy cultivation and management and rich nutrition. Researches show that the crude protein content of the red bean grass hay is generally 13.58% -24.75%, the highest crude protein content in the bud stage can reach 25.6%, the crude fat content is 7.9%, the nitrogen-free extract content is 10.8%, and the red bean grass hay is rich in microelements such as calcium, phosphorus and the like. Red bean stalks are hollow, grass is soft, and fragrant in smell, and animals such as cattle, sheep, rabbits, geese and pigs particularly like feeding in large quantities, and the red bean stalks can not cause abdominal distention, and are called as pasture queen, no matter the red bean stalks are fed in green or silage or hay.
