In this study, we characterized the effects of a diet supplemented with fermented cassava leaves (FCLs) on growth performance, intestinal morphology, the cecal microbiota, and cecal metabolites in hybrid geese. We found that the FCL diet was beneficial to goose growth performance and also promoted a healthy intestinal morphology, as reflected by better morphology properties of the duodenum, jejunum, ileum, and cecum. Moreover, the FCL diet significantly altered cecal microbial diversity and composition, increasing the diversity and abundance of the beneficial Bacteroides. Further, the FCL diet increased the complexity and stability of cecal microbial co-occurrence network interactions as a result of altered topological distributions in the network, such as edges, density, degree, and betweenness. The FCL diet had clear impacts on the composition and abundance of cecal metabolites, with increases in metabolites involved in amino acid biosynthesis, digestion, and absorption, as well as an upregulation of associated metabolic pathways. Based on these benefits to growth performance, intestinal development, and cecal microbe-mediated metabolism in geese, FCLs can be utilized as a reliable feed resource for geese in tropical and subtropical regions.
