Anriansyah Renggaman and Sartika I.A. Sudiarto, alongside collaborators, conducted a study on improving air quality in swine housing through the evaluation of different housing designs and bedding systems. By testing three distinct setups, they examined levels of ammonia, hydrogen sulfide, volatile organic acids (VOAs), particulate matter (PM), and airborne bacteria. Among the systems, the sawdust bedding setup (M3) proved most effective in reducing odorous compounds—recording the lowest levels of ammonia and undetectable hydrogen sulfide. However, it also exhibited higher PM and bacterial levels, suggesting a trade-off between odor control and particulate emissions. This research highlights the importance of integrated environmental design in livestock facilities to support both animal welfare and sustainable farming practices.
