Application of degradation technology of light-emitting diode and auto-monitoring system for harmful substances in farrowing areas of a specific pathogen-free pig farm

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.
