Abstract: The expansion of dairy farming has made manure management a critical bottleneck constraining the sustainable development of the industry. To facilitate the rational utilization of manure and mitigate environmental pollution，this study investigated the resource utilization of manure at several local dairy farms in Jiangyan District， Taizhou. Based on field investigation，this paper systematically analyzes the differences among farms of varying scales in manure collection processes，wastewater treatment，and comprehensive manure utilization methods. Furthermore， the study compares the technical characteristics，economic benefits，and applicable conditions of several treatment models. It recommends that dairy farms select appropriate manure treatment models tailored to their specific local conditions to achieve both environmental and economic benefits.
