Due to the demand for modern goose production and pressure of environmental protection, rearing systems geese are changing from traditional waterside intensive such as floor (FR) cage (CR) systems. However, little is known about effects different on intestinal functions cecal microbial composition. Therefore, this study aimed compare histomorphology composition differences in reared under CR FR at 270 d age. Histomorphological analysis showed that ileal villus height (VH) crypt depth (CD) ratio was significantly greater than (P < 0.001). Taxonomic dominant bacteria microorganisms both were roughly similar, with Bacteroidota, Firmicutes, Fusobacteriota, Proteobacteria being phyla while Bacteroides, Fusobacterium, uncultured_bacterium_o_Bacteroidales genera. Differentially abundant taxa between also identified using Linear Discriminant Analysis Effect Size (LEfSe) 0.05, LDA score > 3.5). Megamonas Anaerobiospirillum enriched group genus level, uncultured_bacterium_f_Rikenellaceae Sutterella group. Notably, we found relative abundance negatively correlated VH VH/CD 0.05). The abdominal fat weight 0.01), whereas positively 0.01). Furthermore, PICRUSt2 indicated lipid metabolism pathways lower FR. In conclusion, compared FR, changed histomorphological characteristics composition, thereby affecting physiological performance.
