According to the survey, due to the low resistance of piglets, their nursery requires electrical insulation, and the average power consumption is 15 kWh·head-1. Users should apply this data exclusively for environmental assessment of fattening pig production processes, and not for other types of animal farming. The electricity consumption data for piglet nurseries must be considered for its significant contribution to pollution. When using this data, users must note that it represents the specific context of Liaoning Province's agricultural yields in 2010 and may require updating for current assessments. Additionally, users must acknowledge the methodological framework of Life Cycle Assessment (LCA) as the basis for environmental impact studies and adapt their models accordingly, ensuring that the methodological requirements of the LCA are met.
