Thermal manipulation (TM) during embryogenesis has emerged as a promising strategy to enhance post-hatch performance and improve resilience environmental bacterial stress, which offers potential alternative reduce the reliance on antibiotic growth promoters (AGPs) in broiler production. This study investigated TM’s ability modulate broilers’ cecal microbiota lipopolysaccharide (LPS)-induced stress. Eggs control group (CON) were incubated at 37.8 °C 56% relative humidity (RH), while TM eggs exposed 39 65% RH for 18 h daily from embryonic days 10–18. Post-hatch, LPS subgroups (LPS-CON, LPS-TM) received intraperitoneal injections, body weight (BW) temperature (BT) monitored. Cecal samples collected microbiome sequencing. Alpha diversity showed no differences (p > 0.05), but beta revealed between groups (PERMANOVA, p < 0.05). Firmicutes Bacteroidota dominated phylum level.
