Abstract: With the intensive development of China's livestock and poultry industry，the substantial generation of manure and wastewater，combined with low rates of resource utilization，has posed significant challenges to the surrounding ecological environment. As natural decomposers in ecosystems， earthworms serve as efficient biotransformation agents，offering a green and sustainable solution for the resource? oriented treatment of livestock and poultry waste. This paper discusses the application of earthworms in livestock production，including the production of high?quality vermicompost organic fertilizer from manure，the processing of earthworms into high?protein feed，and the establishment of integrated planting??breeding system utilizing earthworms. It also provides a comprehensive review of the core biological processes，key technical parameters，and the conversion efficiency of earthworms in treating different types of livestock manure. Furthermore，the integrated value of earthworm ?based technology is evaluated from economic，ecological，and social perspectives. This study offers theoretical references and practical guidance for promoting the application of earthworm technology in the resource utilization of livestock manure and advancing the green and sustainable development of agriculture.
