Abstract: Taking the carbon source and carbon sink in the whole process of animal husbandry production in Shiyan City as the research object, and based on reference to relevant domestic and foreign literature, analysis and research on the whole life cycle of animal husbandry production in Shiyan City were conducted. Direct production and auxiliary production were selected as the system boundaries to determine the emission sources of the three main greenhouse gases （CO₂, CH₄ and N₂O） in the whole process of livestock production, and the carbon emissions and carbon pools of animal husbandry production in Shiyan City from 2011 to 2021 were measured using IPCC inventory estimation method and the LCA model. The results showed that from 2011 to 2021, the total annual carbon emissions during the entire life cycle of animal husbandry in Shiyan City were 112 400 to 198 400 tons, the total grassland carbon pool was 838 600 to 1 489 300 tons, and the total annual net carbon emissions during the entire life cycle were -1 324 800 to -640 800 tons. In addition, the research on the technological path and ecological strategies for achieving low-carbon development of animal husbandry in Shiyan City was conducted, with the aim of providing a basis for better promoting low-carbon and ecological development of animal husbandry, and implementing energy conservation, emission reduction, and resource utilization of livestock and poultry waste.
