ABSTRACT
The primary purpose of this study is to characterize the intestinal microbial communities in Zhedong White geese (a local breed in China) at different reproductive stages and to investigate the relationships between intestinal microflora and geese reproductive states. We performed 16S rRNA sequencing of geese duodenum content samples at three different stages (laying, broody, and recovery stage). Taxonomic analysis revealed that Firmicutes, Actinobacteria, and Proteobacteria were the three most abundant phyla in the duodenum of the laying geese. Cyanobacteria predominated in broody geese, followed by Firmicutes, Proteobacteria, and Spirochaetes. The microbial communities of the recovery geese were dominated by Spirochaetes, Firmicutes, Cyanobacteria, and Proteobacteria. Additionally, the microbial diversity and richness were significantly higher in the laying group than the broody and recovery groups. These results provide a basic profile of Zhedong white goose microbial community for the further study on goose broodiness and microbiology.
