title: Distinctive gut microbial community structure in both the wild and farmed Swan goose (Anser cygnoides).
abstract: Swan goose (Anser cygnoides) is currently one of the most popular economic wildfowl for rare birds breeding industries in several provinces of China. However, the farmed Swan geese, reared in artificial environment and fed on both natural and artificial diets, display a reduced reproductive rate compared to wild species. Little is known about the gut microbiota of this species, which could play a role in nutrient and energy metabolism, immune homeostasis and reproduction. The present comparative study was designed to provide a first characterization of gut microbial communities related to both wild and farmed Swan geese by 16 S rRNA sequences using the Illumina HiSeq platform. The results showed that dominant microbial components in both groups consisted of Firmicutes, Proteobacteria, Bacteroidetes and Actinobacteria. The abundances of these four phyla were not statistically different between the groups. At the genus level, significantly decreased abundance of Clostridium and increased abundance of SMB53, Enterococcus and Paenibacillus were observed in farmed group compared to wild group. The marked differences of genus level group-specific microbes create a baseline for future Swan goose microbiology research and make a valuable contribution to forming relationships between gut microbiota and domestic bird reproduction.
