Livestock and poultry manure treatment methods include dry cleaning manure, water flushing manure, bedding material treatment. The treatment method of water flushing manure is strictly restricted by the "Water Pollution Prevention and Control Action Plan" (referred to as "Water Ten") [88] and the new "Environmental Protection Law", which shows a downward trend year by year; The bedding method has less pollutant discharge and less harm to the environment, and can be directly applied to the field after simple composting, but it is highly restricted by economic cost, and is commonly used in poultry house manure treatment. The environmental harm of dry cleaning is between the two, and the economic cost is lower [89,90]. Users of this data should ensure that the manure treatment processes described are applicable to their specific context, taking into account local regulations such as the 'Water Pollution Prevention and Control Action Plan' and the 'Environmental Protection Law.' Consideration should be given to the decreasing trend in the use of water flushing manure treatments and the preference for bedding material treatment or dry cleaning manure due to the lower environmental impact. Users must also account for the economic costs associated with these treatments. When using this data to support decision-making in animal farming sustainability, users should integrate this information with local practices, environmental considerations, and cost-benefit analyses to determine the most suitable manure management strategy.


In this paper, the life cycle of livestock and poultry farming is divided into six stages: feed crop planting, feed processing, livestock and poultry raising, manure treatment, slaughter and transportation. The specific life cycle process of livestock and poultry breeding is shown in Figure 2-1. Due to the lack of some data and the limitations of basic conditions, the production, transportation and use of pesticides, mulch and feed additives have not been analyzed, and the environmental impact caused by other related infrastructure construction, transport production and labor costs is no longer considered.
