The pollutants released to the environment during the feeding stage of broilers are mainly divided into the broiler itself and other energy consumption. Users should note that the LCA data set specifically reflects the environmental impact of broiler rearing in a large-scale setting in Shandong province. Users must consider the location-specific nature of this data when applying it to other geographic contexts. Care must be taken to account for regional differences in rearing practices and energy consumptions. Data users should ensure that the functional unit of 1 kg of chicken matches the scope of their sustainability assessment or ecological footprint calculations. It is essential to include all relevant inputs and outputs during the feeding phase and to understand that this data set may not fully represent the environmental impact of chicken production in different contexts or scales.
