| Geographical representativeness description | Since the agricultural resource consumption is allocated according to the occupied land, the specific crop yield is no longer considered in scenario A, and the concentrated feed and the full-priced feed under various scenarios are converted into equivalent land area according to the corresponding average yield of main grains in the whole country or Sichuan province according to the set two situations. |

| Use advice for data set | 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. |
| Technical purpose of product or process | The data represents the pig production process in Sichuan, China, specifically within specialized households of moderate scale located in hilly and plain areas. The pigs are raised primarily for producing commercial pork with an emphasis on the balance of energy and protein in their feed, which consists of locally sourced corn and purchased concentrated feed, supplemented by full-priced formulated feed. It outlines a typical scenario where pig breeds are predominantly foreign hybrids, with specific slaughter rates and a feed to meat conversion ratio provided. This data can be utilized for environmental impact assessments within the realms of agricultural and food industries, especially focusing on sustainable pig farming practices. |

| General comment on data set | 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. |

| Functional Unit | In this study, the functional unit (FU) was defined as "1kg pig carcass", which included skin, bone and fat. Foreign studies generally only considered lean meat, but in China's consumption mode, skin and viscera were also fully utilized as edible foods. The concept of carcass was adopted in this study. Although the bone included in this study is an inedible part, it can play a certain compensative role because it does not contain internal organs. In addition, the current data can be easily converted into carcass weight, so it is more in line with the actual situation. |
| Time representativeness | |
| Time representativeness description | The average level of energy consumption and the amount of fertilizer, pesticide and mulch used in feed raw materials production in Sichuan Province was calculated according to China Statistical Yearbook 2006. |
| Technological representativeness | |
| Technology description including background system | 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. |
