[0002] Hay is a high-quality feed, rich in nutrients such as cellulose, protein and vitamins. It is one of the main feed materials for livestock. Hay can provide rich nutrition, promote the growth and development of livestock, enhance their immunity and improve production performance. For farmers, this means better breeding benefits and economic returns; hay can also be used as agricultural bedding. Because of its excellent water absorption and heat preservation properties, laying hay in the livestock house can provide a comfortable resting environment for animals, and can also effectively maintain the hygiene of the livestock house and the health of animals, which plays a positive role in the sustainable development of animal husbandry; in addition, hay is also an important agricultural organic fertilizer. Using hay for covering or returning to the field in farmland can help improve soil fertility, improve soil structure, reduce soil erosion, and promote plant growth, which is of great significance for achieving sustainable agricultural development and protecting the ecological environment.
