Description

Large-scale intensive feeding in hilly and plain areas. It provides about 1.5% of Sichuan's commercial pigs, and plays a major role in modern pig farming in Sichuan. The main scenarios and parameters of this pig raising scenario are as follows: (1) Energy feed is mainly corn and other grains, all feed raw materials are purchased from outside the system, the feeding period is about 170d, and the average output is 95kg; ② The average number of listed is 5000 per year, most of the varieties are foreign three yuan hybrid pigs (such as DLY, a few are PIC commercial pigs), the slaughter rate is 76%, and the whole feed meat ratio is 3.0:1; ③ The feeding management is more advanced, the use of a large number of modern pig technology, generally self-breeding, the use of limit column and high bed feeding. ④ Fecal treatment and utilization: fecal and sewage anaerobic fermentation treatment. 70% is shipped out to return to the field (at present, this level has not been reached, assuming that this goal can be achieved in the next 5 years due to the strict implementation of environmental protection laws and regulations) long-term storage accounted for 45%, 30% after anaerobic fermentation treatment and put into the surrounding environment discharge water COD is 200mg/L. When utilizing this data set for Life Cycle Assessment (LCA) of pig production, account for the following: 1) The Functional Unit (FU) defined as '1kg pig carcass', which includes skin, bone, and fat. Adjust comparisons and analyses for this FU when relating to other regional LCA studies that may consider only lean meat. 2) Regional variation in feed ingredient production, energy consumption, and agricultural input such as fertilizers and pesticides should be taken into account based on 2006 statistical yearbook data. 3) Environmental impacts associated with waste management should include the current scenario and projected improvements in the next five years due to stricter environmental regulations, with a focus on anaerobic fermentation of waste. 4) Crop yield data used for the calculation of agricultural resource consumption should be carefully applied as per scenario details provided. Always consider technological applicability, taking into account local standards and regulations for environmentally sound pig farming practices.

Technology

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.
