In hilly areas and plain areas, professional households raise on a moderate scale. It provides about 19% of the commercial pigs and plays a major regulatory role in Sichuan's pig industry. The main scenarios and parameters of this pig raising scenario are: (1) 50% energy feed is mainly corn in the province, and protein feed is mainly concentrated feed; The other 50% feed is purchased at full price. The average weight was 80kg during 160 days of feeding. (2) The number of pigs raised by professional households fluctuates greatly with market changes, and the average number of pigs raised in this study is assumed to be 100 / year. 70% of the breeds are foreign two-hybrid pigs (cross-bred offspring between the two lines), the slaughter rate is 75%, 30% are foreign three-yuan (such as DLY), the slaughter rate is 76%, the whole feed meat ratio is 3.2:1; ③ Feeding management: pay more attention to the rational preparation of feed, but the environmental management is poor; (4) Waste treatment and utilization: Without treatment,40% is returned to the field (long-term storage accounts for 8%),60% is discharged to the surrounding environment, and the COD of the discharged water is 400mg/L. When applying this data set in a Life Cycle Assessment (LCA), users should note that it has been framed within the specific context of Sichuan's pig farming practices. The data is not designed to be universally applicable but rather contextualized for localized agricultural inputs and outputs. For LCA modeling, it is advised to take into consideration the particularities of feed composition, regional resource consumption patterns, and waste treatment practices highlighted in the data. It is essential to not extrapolate these findings to dissimilar agricultural contexts without appropriate adjustments. Caution should be used when attempting to generalize the environmental impact results to other regions or scales of operation.


Soybean meal (70%) and rapeseed meal (10%) were analyzed in concentrate, and other components were not considered. The components of the full price feed are mainly corn based grains (70%) and soybean meal (25%), and the other components are not considered. Minerals, disinfectants and various small equipment facilities are not included.
