This research aimed to assess the impact of fermented Citri Sarcodactylis Fructus by-products (FCSF) on growth performance, gut digestive enzyme activity, nutrient utilization efficiency, microbiota, and their metabolites in broiler chickens. A total 1,080 male chickens were allocated into four groups (T1-T4) consisting 6 replicates per group, each containing 45 The basal diet was provided group T1, while T2, T3, T4 supplemented with 1%, 3%, 5% FCSF diet, respectively. experimental period 42 days. findings revealed that supplementing improved FW ADG chickens, led a reduction F/G, ADFI, mortality rate (p < 0.05). Furthermore, supplementation 3% thigh yield, semi-eviscerated carcass slaughter lipase activity duodenum ileum birds Additionally, enhanced protease broilers Moreover, phosphorus, dry matter, crude protein, ash feed by Compared control reduced serine content chicken breast meat Supplementing 1% significantly increased C14:0, C14:1, C20:1 compared other levels C20:4n6 C23:0 lower than T1 ∑ω-3PUFA decreased after 16SrDNA showed ACE, Chao1, Shannon indices cecum also abundance phylum Desulfobacterota genera Coprobacter Prevotella Metabolomic analysis microbiota upregulated downregulated 16 12 metabolic pathways 3 In summary our indicate can improve performance enhancing intestinal utilization, improving microbial diversity, influencing metabolism microbiota.
