Geese are extremely well-adapted to utilizing plant-derived roughage in their diet, so the grass must be added commercial diets under intensive rearing systems. However, it is unclear whether gut microbiota will change significantly when adding different proportions of ryegrass. In this study, 240 healthy male Yangzhou geese (28 days old) with similar body weights were randomly divided into four groups and fed (CK, whole diets; EG1, ryegrass: = 1.5:1; EG2, 2:1; EG3, 3:1) respectively. When grew 70 old, intestines collected high-throughput sequencing technology was performed investigate microbial diversity caecum dietary supplements. There no obvious alpha ryegrass intake (P > 0.05) composition dominant bacterium (including Bacteroidetes Firmicutes) also similar. ratio between Firmicutes remarkably reduced < 0.05), relative abundance 30 operational taxonomic units (OTUs) differed. Additionally, content cellulose-degrading such as Ruminiclostridium Ruminococcaceae UCG-010 increased increasing amounts grass. Finally, functional profiles goose explored using PICRUSt tool. Carbohydrate metabolism amino acid metabolic pathways. Lipid EG3 compared that CK group 0.05). Interestingly, Turicibacter Parasutterella may have affected abdominal fat deposition increased. Taken together, although bacterial communities ryegrass, (Ruminiclostridium UCG-010) abundant lipid pathway enriched, which reduce accumulation high-ryegrass geese.
