Optimization of Solid Waste Resource Utilization Mode Of Different-scale Dairy Farms from the Cost – Benefit Perspective

This study analyzed the cost – benefit of manure resource utilization using micro-investigation data of 89 large-scale dairy farms in Horinger County and Tumote Zuoqi, Inner Mongolia, China. Results showed that the applicable economic utilization modes of manure resources in smalland medium-scale farms are fertilizer sale and bedding production, respectively. However, the lack of market demand for organic fertilizer and technical equipment restricts their promotion of applicable economic models. Large- and ultra-large-scale farms are using manure resources as fertilizer, which is limited owing to the shortage of supporting cultivated land. Moreover, farms of different scales did not make profit from the utilization of manure resources, where large-scale farms suffered the highest degree of loss. Therefore, this study proposes to strengthen the supervision of, and technical support, for large-scale farms, completely promote tripartite governance, increase technology research, and encourage the implementation of cooperative planting and breeding and other countermeasures.
