Description

In dairy farming, the difference between the two models is the source of silage corn feed. Data users should take note of the distinctive characteristics of the non-IPBS dairy farming system when utilizing this LCA data. It is crucial to differentiate between the non-IPBS and IPBS models, particularly regarding silage corn feed source, feed transportation distance, feed cost, and the utilization pathways of organic and liquid fertilizers. Ensure correct application of the provided values by taking into account that all inputs and outputs are calculated based on FPCM per ton, along with average input per hectare for comparison with relevant studies. Reference to specific research (indicated by [20]) is required when addressing areas of uncertainty, such as diesel consumption for farm tillage operations.

Technology

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.
