Abstract: With the large-scale and intensive development of animal husbandry, livestock and poultry breeding has become one of the main sources of agricultural non-point source pollution in China. The resource utilization of livestock and poultry manures is not only critical for ensuring the healthy and sustainable development of animal husbandry, but it is also a vital step toward achieving the long-term goal to construct ecological civilization and build a community with a shared future for mankind from the perspective of sustainable development. The ability to achieve coordination and unity in livestock and poultry pollution management and economic development is made possible by the agricultural production mode of planting-breeding combination. Through analyzing the origins of greenhouse gases in production, processing and consumption of animal husbandry, this paper summarizes the general solutions of source reduction, process control, and end treatment of livestock and poultry breeding, in hoping to provide references for farm households, animal breeding enterprises, and local governments with similar characteristics, to improve the resource utilization efficiency of livestock and poultry manures, and to promote carbon neutrality in animal husbandry.

Key words: animal husbandry, carbon emission reduction, carbon neutrality, planting-breeding combination, greenhouse gases
