Abstract: This study investigated the effects of dietary Edible Dock Powder (EDP) on growth performance, organ development, serum biochemistry, and cecal microbiota in Sanhua goslings. A total of 240 goslings were randomly allocated into four groups: one control group (Group A) and three experimental groups supplemented with EDP at concentrations of 1.00% (Group B), 2.50% (Group C), and 4.00% (Group D). Group B showed a significantly decreased feed-to-gain ratio (F/G) compared to the control group ( p < 0.05). Organ analysis indicated an increase in liver and glandular stomach weights in Groups B and C ( p < 0.05). Serum aspartate transaminase (AST) levels were significantly decreased in the EDP groups ( p < 0.05), and glucose (GLU) levels were notably lower in Groups C and D compared to the control group ( p < 0.05). Cecal microbiota analysis revealed that Group B was enriched in Prevotella and Streptococcaceae , while Cyanobacteria and Alistipes were higher in Group C. Additionally, Desulfovibrio was positively correlated with glandular stomach weight, and Oxalobacter with ADG ( p < 0.05). These findings suggest that 1.00–2.50% EDP supplementation supports growth, enhances liver and gut health, and optimizes microbiota composition, providing a viable functional feed strategy for goslings.
