In IPBS wheat-silage maize rotation cultivation, the main inputs of production materials are chemical fertilizer, organic fertilizer, pesticide, seed, etc. The products are wheat, wheat straw and rice silage. Among the products, all wheat is sold, all wheat straw is returned to the field, silage corn is used to feed dairy cows; There was no silage planting link in non-IPBS When utilizing this LCA data for analyzing the environmental impact of milk production processes, note that the data is specific to the IPBS cultivation system in Shandong Province, China, with a focus on the rotational cultivation of wheat and silage maize. The data includes input-output lists for resources consumed and produced per ton of Fat and Protein Corrected Milk (FPCM). Care should be taken to accurately account for diesel consumption in mechanical operations, based on substitute figures from relevant research [20], where direct data is unavailable. The benefits of the rotational system, including reduced feed transportation costs and different utilization pathways for organic fertilizers, should be reflected in comparative studies.


In the study area, there are mainly two milk production modes :IPBS and non-IPBS. In non-IPBS, the farms only have feeding links and manure treatment links, all the feed is purchased, and the manure pile fertilizer is made into organic fertilizer and sold to fruit and vegetable farmers. In IPBS, the silage corn planting process is increased in the farm, organic fertilizer and liquid fertilizer are mainly applied to the farm field, and the remaining part is sold to fruit farmers and vegetable farmers, etc. The differences between the two models are as follows :1) the sources of silage corn in the farm are different, resulting in different feed transportation distances and feed costs; 2) The use of organic fertilizer and liquid fertilizer is different, and the transportation distance is different. A total of 109 dairy farms were investigated in this study, and 83 valid questionnaires were obtained after excluding non-conforming questionnaires, among which 38 were non-IPBS and 45 were IPBS.
