This study investigated the effects of WO3-based photocatalytic bactericide on piggery environment, microorganisms in pig manure, and weaned piglets. After spraying bactericide, NH3 concentration decreased by 31.25% within 1 h then returned to pre-spraying after 24 h. The airborne aerobic bacteria level before was 3.99 × 105 colony-forming unit (CFU)/m3, which dropped 2.45 CFU/m3 spraying, with a bactericidal rate 38.58%. 3.3 17.32%, 3.61 48 9.44%. concentrations total suspended particulate (TSP), matter (PM) 10, PM 2.5 31.1%, 43.0%, 32.5%, respectively. abundance some potentially pathogenic TSP 2.5, such as Staphylococcus, Enterococcus, Streptococcus, significantly reduced 16sDNA sequencing for time (p < 0.05). At certain times following application levels bacteria, Pseudomonas, Flavobacterium, Stenotrophomonas walls were Overall, this provided research direction improving environmental quality promoting healthy growth piglets well future development new products.
