Abstract: The development of modern large-scale cattle farms has been rapid, providing a large amount of high-quality milk and meat for citizens. However, at the same time, the amount of waste such as feces and sewage produced by these farms has increased, and most of them cannot be properly treated. The accumulation of manure in the production area not only causes pollution to the surrounding soil, air, and water bodies but also affects the normal breeding and production order of the cattle farm. This seriously harms the ecological environment and affects the green and sustainable development of the cattle industry. Therefore, the problem of treating and utilizing cow manure as a resource needs to be urgently addressed. To stabilize and safely handle the manure, this paper proposed to utilize the manure from large-scale cattle farms as a resource. This not only solved the problem of manure pollution in cattle farms but also maximized the utilization of manure resources, which was of great significance. This paper analyzed the nutritional composition of cow manure and the environmental pollution caused by manure from large-scale cattle farms. The purpose, principles, and expected effects of resource utilization of manure were briefly described. Existing methods of cow manure resource utilization were also introduced, including energy utilization, substrate utilization, feed utilization, fuel utilization, fertilizer utilization, and the reuse of oxidized pond fermentation. By analyzing various resource utilization technologies and applying them according to specific situations, or implementing multiple technologies in combination, the limitations of a single technology can be avoided. This paper provided a reference for the treatment of manure in different breeding environments and provided a reference for the low-carbon and sustainable development of modern cattle farming.In the future, efforts should be made to further promote the resource utilization of manure from large-scale cattle farms. Scientific and reasonable plans for manure treatment and resource utilization models should be developed in various regions. The quality of the surrounding environment should be monitored, and effective control measures should be taken to promote the healthy development of animal husbandry and lay the foundation for the circular economy and comprehensive utilization of the animal husbandry industry.
