Alternative management strategy influences litter microbiome dynamics in a commercial broiler rearing system

Alternative litter management with IndigoLT and reduced NaHSO4 alters microbiome diversity and reduces Enterococcus, including pathogenic E. cecorum and E. hirae, in broiler systems.

• Why it matters: Controlling pathogen populations in broiler litter is crucial for improving flock health and reducing disease transmission, yet current strategies often have transient effects and overlook microbial interactions.
• What they did: The study applied an innovative management approach across two broiler growouts, analyzing microbiome structure, physicochemical properties, and Enterococcus abundance through sequencing and digital PCR, complemented by biofilm and growth-inhibition assays.
• The result: This biologic-based strategy significantly changed microbial community composition and decreased pathogen-associated bacteria, supporting its potential to enhance pathogen control and promote healthier broiler production.
