Abstract: Carbon emissions from livestock and poultry farming account for a large proportion of China's agricultural carbon emissions, and carbon emission reduction actions are urgent．Partial life cycle method was used to evaluate carbon emissions in production process of large-scale laying enterprises．Results showed that greenhouse gases mainly came from electricity consumption, manure treatment and fuel combustion．To reduce carbon emissions during poultry production process, efforts should be made to establish a carbon emission monitoring system, promote circular poultry production practices, focus on developing clean energy and energy-saving technologies, and fundamentally reduce carbon emissions．
