Age-dependent variations in aerosol-borne particulates and microbial communities in multi-tier broiler housing systems: A metagenomics environmental health risk assessment.

ABSTRACT: By investigating the temporal dynamics of airborne microbial communities associated with particulate matter in multi‑tier broiler housing, this study offers a systematic reference for understanding how environmental microbiota shift with broiler age. Fine particulate matter (PM_2.5) and total suspended particulate (TSP) were collected from the housing environment at three growth stages: D10 (10-day-old), D24 (24-day-old), and D38 (38-day-old). The concentration and LPS content of the collected TSP and PM_2.5 samples from each stage were measured, followed by metagenomic sequencing. Results revealed that the concentrations of TSP and PM_2.5 peaked at D24 (P < 0.05), showing a trend of first increasing and then decreasing, and the change trend of mortality in th
