The aim is to understand how replacing soybean meal with black soldier fly larvae meal impacts health indicators in chickens.
Experiment with different proportions of black soldier fly larvae meal (0.0%, 3.9%, 7.8%, 11.7%, and 15.6%) for 56 days.
Measure serum levels of antioxidant and immune indicators.
Assess intestinal health through villus-to-crypt ratio and gene expression.
Analyze caecal microbiota composition and metabolites.
11.7% BSF group showed significant increases in serum antioxidant and immune markers.
Improved intestinal health with higher villus-to-crypt ratios and better gene expression levels.
Alterations in caecal microbiota composition with 10 distinct bacterial genera observed.
424 differentially expressed metabolites linked to enhanced immune function and gut health.
