“…First of all, three scales exist difference in the number of pig farms, breeding costs, farming methods, yield and breeding profits [8,9]. Secondly, infrastructure, rural human capital level, and environmental management level of breeding technology also produce diverse effects depending to the distinct scale of pig breeding [10][11][12]. Thirdly, the amount of manure and urine produced during pig breeding of unequal scales are different, thus the pollution emissions of chemical oxygen demand (COD), total nitrogen (TN) and total phosphorus (TP) converted from them are various [13][14][15].…”

The pig industry occupies an extremely significant position in agriculture. The input cost, output income and the amount of pollution emitted by pig farming of different scales are unequal. It is of great practical importance to reduce pollutant emission by improving efficiency for the development of hog breeding industry in China. With the addition of undesirable output, this paper uses the Slack Based Measure- Metafrontier Malmquist Luenberger index model considering scale heterogeneity to explore the evolution characteristics of China’s green total factor productivity of pig breeding (GTPB) based on the data of China’s 17 major pig producing provinces from 2004 to 2018. The results indicate that: (1) From 2004 to 2018, China’s large-scale GTPB is the highest, the medium-sized is the second, and the small-scale is the lowest. (2) In terms of regional distribution, China’s GTPB in western region is the highest, in eastern region is the second, and in central region is the lowest. (3) China’s GTPB shows efficiency growth and technological decline from 2004 to 2018. The pig breeding industry is generally fragile, which is greatly affected by emergencies. (4)The TGR of large-scale pig breeding is closest to 1, followed by middle-scale, and finally small-scale. According to the above empirical results, this text puts forward some policy suggestions to improve GTPB and environmental protection recommendations of hog breeding.

“…Although the respirable dust is still below the Occupational Safety and Health Administration's permissible exposure level, it surpasses the limit for animal buildings suggested by other studies (Jerez et al, 2014). Some nearby inhabitants were also exposed to harmful odour compounds such as ammonium, dimethylamine, trimethylamine, butyric acid, phenol, and indole that may irritate the human respiratory tract (Fan et al, 2020). Additionally, since poultry manures may also spread some bioaerosol-containing harmful pathogens, excessive and sustained intake of these pathogens might result in the fatal illnesses listed in Table 1.…”

Indiscriminate manure disposal has been highlighted as a significant cause of environmental contamination due to the presence of various biological and chemical irritants. It includes pathogens, antibiotics, and organic pollutants, all of which have the potential to harm not only the environment but also human health. Several incidents have been reported, most notably among farmers and those living near the farms, as a result of air and water pollution caused by manure losses. Acute and chronic exposure to these hazards may result in a variety of health issues, including infection, inflammation, and even cancer. Despite this, humans are constantly exposed to these risk agents due to a lack of awareness of proper disposal methods and knowledge of the risk agents' associations with diseases. Thus, the review discusses the potential health risk or diseases linked to poultry manure and recommends future measures to minimise the hazards to farmers' health and the environment posed by their existing practices.

“…The pollution caused by swine wastewater causes public health problems, threatens public safety, and causes serious negative social impacts. One study [28] found that the more households engaged in pig farming in a certain area, the higher the health risk of the local people; moreover, the larger the proportion of large-scale farming, the higher the health risk of the people. In addition, the development of the pig industry often ignores the ecological recycling of waste, which not only fails to reduce the use of local pesticides and fertilizers but also increases the health risks of people and consumes great amounts of social resources, causing social security problems [13].…”

Swine wastewater contains large amounts of organic matter, nutrients, toxic metal elements, and antibiotics. If it is directly discharged or not properly treated, it poses a significant threat to the environment and human health. Currently, the management of swine wastewater has become a focus of social attention, and it adopts a dual-track parallel model of standard discharge supplemented by resource utilization. If treated properly, it can achieve the recycling of water resources and promote the effective recovery of resources. Based on the pollution characteristics of swine wastewater, this paper analyzes its impact on the environment, society, and the economy in detail and expounds on the research progress of swine wastewater treatment technology. From the perspective of resource utilization and recycling of anaerobic digestion liquid (biogas slurry) from swine wastewater and the carrying capacity of the soil environment and cumulative ecological environmental risks, this study explores new development trends and application prospects for swine wastewater treatment technology.
