Oat is a high-quality gramineous pasture, and alfalfa is a leguminous pasture. Protein content of leguminous forage is high. The two grasses complement each other, and oat grass has high digestibility, which is generally used as high-quality roughage for dry milk of dairy cows during perinatal period. Medicago sativa during lactation.

The low nutritional content or too little supply of forage grass for raising dairy cows will directly affect the milk yield of dairy cows. Therefore, it is necessary to feed cattle with forage plants with high nutritional content, so cattle farmers often feed cattle with forage grass with high nutritional content such as alfalfa and oatmeal.

Alfalfa is the "king of pasture". It is rich in vitamins, which can not only improve the reproductive ability of dairy cows, but also increase their milk production, and has good palatability. Therefore, dairy cows like to eat this pasture very much, and it has strong regenerative ability, so there is no need to worry about the supply of pasture. Like to grow in dry and warm areas, loose and well-drained soil is more suitable for alfalfa growth, which can not only improve yield but also improve plant quality.

Oatmeal is a plant with high sugar content. The roots of this plant are tough and widely distributed in China. Oatmeal can be made into hay after harvesting, with high protein content and good palatability. It is also very suitable for feeding cows.

Forage with high nutrient content plays a very important role in the growth and development of dairy cows, so dairy cows are generally fed with forage with rich nutrient content and good palatability, such as alfalfa and oatmeal.
