摘要：Introduction and Objective. In the last decades, large-scale swine production has led to intensive rearing systems in whichair quality can be easily degraded by aerial contaminants that can pose a health risk to the pigs and farm workers. This studyevaluated the effects of fogging disinfectant procedure on productive performance, ammonia and dust concentration,aerobic bacteria and fungal spores spreading in the farrowing–weaning room.Materials and Method. This trial was conducted in 2 identical farrowing-weaning rooms of a piggery. In both rooms,30 pregnant sows were lodged in individual cages. At 75 days of age, the piglets were moved to the fattening room. In thetreated room, with the birth of the first suckling-pig, the fogging disinfection with diluted Virkon S was applied once a dayin the experimental room per 15 minutes at 11:00. The fogging disinfectant treatment was switched between rooms atthe end of the first trial period. Temperature, relative humidity, dust (TSP-RF fractions and number of particles), ammoniaconcentration and aerial contaminants (enterococci, Micrococcaeae and fungal spores) were monitored in both rooms.Results. Ammonia concentration reduction induced by fogging disinfection was estimated 18%, total suspended particlesand the respirable fraction were significantly lower in the experimental room.Fungal spores resulted in a significant reduction by the fogging procedure, together with dust respirable fraction and fineparticulate matter abatement.Conclusions. The fogging disinfection procedure improved air quality in the piggery, thereby enhancing workers andanimals health.
