a Chao1 α diversity index comparing microbiome richness across diet groups: MOM, Holder, and Retort. The Holder group exhibited significantly higher Chao1 diversity compared to Retort (p = 0.007), while neither Holder nor Retort differed significantly from the MOM group. b Distance-based Redundancy Analysis (dbRDA) plot illustrating β diversity between groups while controlling for delivery method, antibiotic exposure, and sex. Diet, specifically Holder and Retort, significantly influenced microbiome composition (p = 0.017 for both). Delivery method also had a significant impact (p = 0.001), whereas antibiotic exposure (p = 0.266) and sex (p = 0.625) were not significant.
