| Abstract: |
| The relevant literature published over the last 20 years in the field of pollution prevention and control technologies for breeding industries was analyzed using bibliometric methods. The research hotspots and development directions in the field were predicted by analyzing the relevant technical fields from the perspective of source reduction, process control, and waste recycling. The data from this study will help improve the agricultural non-point source pollution prevention and control system in China. The results showed that, in the field of breeding industries, domestic research focused on swine pollution, while foreign research focused on beef cattle（cow）. There was insufficient attention focused on aquaculture pollution, both locally and internationally. In the fields of livestock and poultry pollution control, the recycling of animal manure was the key research topic. Research on composting and anaerobic fermentation was found to be very popular in China, and these investigations were mainly related to soil pollution. The research focus in other countries was more comprehensive and included waste recycling, energy utilization, breeding wastewater treatment, and greenhouse gases. In the next few years, China can further expand technologies to diversify animal manure treatment, based on the utilization of waste resources, paying special attention to the development and utilization of clean energy. Moreover, theoretical and technological research on water pollution and air pollution due to breeding industries needs to be further expanded. This will improve the pollution-control technologies used by breeding industries and thus, enhance pollution prevention and control. |
