Thermophile-Fermented Compost Reduces Hen Mortality During Heat Stress
Yudai Inabu et al. (2026) report that oral administration of compost fermented by thermophilic Bacillaceae reduced heat-stress mortality in a field study of 601,474 laying hens across eleven houses during summer (≈35 °C). Microbiome sequencing showed increases in Lachnospiraceae, Lactobacillus and SCFAs acetate and butyrate, with reductions in Romboutsia and Escherichia-Shigella. The authors link mortality reduction to gut microbial shifts and elevated SCFAs.
Key Points
- 1Demonstrates reduced heat-stress mortality after oral administration of thermophile-fermented compost to 601,474 hens.
- 2Links mortality reduction to increased acetate and butyrate and shifts in key gut bacterial genera.
- 3Suggests microbiome-targeted feed additives can enhance poultry heat resilience and inform management strategies.
Scoring Rationale
Strong peer-reviewed field evidence with actionable outcomes, but limited relevance beyond poultry microbiome and not AI/DS-focused.
