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.

摘要： 随着我国畜禽养殖业集约化发展，畜禽粪污产量巨大且资源化利用率低，给周边生态环境带来了严峻的挑战。蚯蚓作为生态系统中的“分解者”，是一种高效的生物转化媒介，能够为畜禽粪污的资源化处理提供绿色可持续的解决方案。该文阐述了蚯蚓在畜禽养殖业中的应用方式，包括用蚯蚓处理粪污生产优质蚯蚓粪有机肥，将蚯蚓加工成高蛋白饲料以及利用蚯蚓构建种养循环系统，重点综述了蚯蚓转化畜禽粪便的核心生物过程、关键工艺参数及其对不同畜禽粪污的转化效果，并从经济效益、生态效益和社会效益三方面评估了蚯蚓的综合价值，为蚯蚓在畜禽粪污资源化处理与农业绿色可持续发展中的深入应用提供理论参考与实践指导。
