| Use advice for data set | When utilizing the dataset for Life Cycle Assessment (LCA), users must consider the focus on corn, soybean meal, and wheat bran in the dietary formulation for dairy cattle. The functional unit of 1 ton FPCM should be used as the basis for environmental impact assessment, ensuring comparability across studies related to milk production. It's critical not to consider additional components that are not main constituents of the dairy cow's full price feed within the scope of this LCA study. Users should also factor in the various stages of feed raw material production, including fertilizer production, crop cultivation, and processing of soy and wheat bran, when conducting their assessments. |
| Technical purpose of product or process | The described industrial process is utilized in the dairy industry, specifically within the context of a dairy farm production system in Heilongjiang Province. The process involves production of feed raw materials for milk production, which includes the production of fertilizers and the cultivation of corn, soybeans, wheat, and alfalfa. Additionally, the process entails producing feed components such as wheat middlings and soybean meal. These components are critical in formulating full price feed and coarse feed for dairy cows, with an emphasis on the inclusion of corn, soybean meal, and wheat bran in the full price feed. This technical process is integral for ensuring the necessary nutrient composition of feed for dairy cows, aimed at producing high-quality Fat-Protein Corrected Milk (FPCM). |

| Functional Unit | In this study, the functional unit was set to 1 ton FPCM (fat-protein corrected milk). |
| Technological representativeness | |
| Technology description including background system | The word feed of dairy cow is composed of two parts: full price feed and coarse word feed. In the full price feed of dairy cow word feed, rice, soybean meal and wheat bran are the main components, so other components are not considered. The production stage of feed raw materials mainly includes fertilizer production stage, crop planting stage and soybean and wheat bran processing stage. |
