“…To challenge these di culties, the in uence of sampling methods on the composition and function of the intestinal microbiota are urgently needed. The donkey and cow as typical monogastric and polygastric animals are crucial domesticated animals, in which make valuable contributions to various agricultural industries and serve as food for humans and the intestinal segments of the digestive tract are easily distinguished 10,11 . In addition, compared with amplicon sequencing, metagenomic sequencing could identify organisms from all domain of life and obtain both structural and functional data 12 .…”

Intestinal microbiota plays a crucial role in the health and diseases. However, very little is known about the impact of sampling methods on assessing intestinal microbiota. In this study, we investigated and compared the influence of sampling methods on the intestinal microbial community composition and function using approximately 300 GB of metagenomic sequencing data from 91 samples representing different digestive tract segment with swab and fecal samples of monogastric (donkeys) and polygastric (cows) animals. We assembled 4,004,115 (cow) and 2,938,653 (donkey) contigs, and got 9,060,744 genes showing the swab sampling revealed a higher abundance of Bacteroidetes, while the fecal sampling showed a relatively higher proportion of Firmicutes. In addition, we observed the significant variations in the microbial composition between different digestive tract segments in both animals. Finally, our study identified several key species and pathways in different of sampling methods and provided evidence that sampling methods can influence their co-abundance relationship, which expands our current knowledge using appropriate sampling methods to accurately characterize the gut microbiota composition and function.
