Abstract: 
In pig farms, disinfectants are applied for the effective cleaning and disinfection regimen. Moreover, the ideal detergents should be left no residue after use which might harbour micro-organisms. Additionally, it should be non-toxic to pigs and must have minimal environmental impacts. Therefore, in order to avoid detergent residues and possible effects on pigs, staffs, and environment, the development of a novel technology without chemicals to kill micro-organisms, degrade atmospheric fine particulate matter and harmful gases in the pig farms is pioneering and future potential. In this study, application of degradation technology of light-emitting diode (LED) and auto-monitoring system for harmful substances in farrowing area of a specific pathogen-free pig farms. The LED light exhibit an antibacterial efficacy of up to 89.1%. They are capable of reducing ammonia concentrations within the environment by 45%, hydrogen sulfide levels by 68.8%, and curbing PM2.5 concentrations by 80%. Collectively, these findings underscore the considerable potential of this degradation technology via visual light in effectively eliminating detrimental substances.
