Alfalfa is a good forage grass. Its plant height is 50 cm to 90 cm. Cows, horses, sheep, pigs and chickens all like to eat it. It grows fast, does not need feeding, does not get sick, and its fur looks smooth and shiny. Cutting and drying in late autumn is an excellent forage for livestock to overwinter, and the yield per mu is 1500-2000 kg.
