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.
