| Use advice for data set | Users applying this data set for Life Cycle Assessment (LCA) purposes should carefully model the dairy farming system by considering the distinct stages of dairy cow production: breeding, lactation, and dry periods. The pollution emissions from the pick-up period are excluded in this study and should be taken into account if relevant. The functional unit for the study is 1 ton of FPCM (fat-protein corrected milk), which should be consistently applied when modeling the environmental impact. This data set should be used to assess the environmental impact of dairy production in Heilongjiang Province and may require regional adaptation when applied to different locations. |
| Technical purpose of product or process | This data set describes the milk production process at the cow production stage, specifically for Holstein dairy cows. The described application is relevant to agricultural operations focused on dairy farming and milk production, including the management and care of dairy cows through various stages such as breeding, lactation, and dry periods. This information is particularly useful for dairy farms, agricultural researchers, and food industry stakeholders who aim to understand and optimize milk production, as well as assess the environmental impact of dairy farming operations in Heilongjiang Province. |
