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 . 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.
在本研究中，我们表征了添加发酵木薯叶（FCL）的日粮对杂交鹅生长性能、肠道形态、盲肠微生物群和盲肠代谢产物的影响。我们发现，FCL日粮有利于鹅的生长性能，还促进了健康的肠道形态，十二指肠、空肠、回肠和盲肠更好的形态特性反映了这一点。此外，FCL日粮显著改变了盲肠微生物多样性和组成，增加了有益菌的多样性和丰度。此外，由于网络中边、密度、度和介数等拓扑分布的改变，FCL日粮增加了盲肠微生物共现网络相互作用的复杂性和稳定性。FCL日粮对盲肠代谢产物的组成和丰度有明显影响，参与氨基酸生物合成、消化和吸收的代谢产物增加，以及相关代谢途径的上调。基于对鹅生长性能、肠道发育和盲肠微生物介导的代谢的这些益处，FCL可作为热带和亚热带地区鹅的可靠饲料资源。
