英文摘要	Ex situ conservation is the main method for the protection of endangered wildlife. To explore the effect of ex situ conservation on the gut microbiota of the kiang (Equus kiang), metagenomic sequencing combined with bioinformatics analysis was used to investigate the composition and function of the gut microbiota of the kiang. The results showed that ex situ conservation not only protected wildlife, but also affected the composition and function of gut microbiota, as well as the health of animals. In the zoo, the ratio of the relative abundance of Firmicutes to that of Bacteroidetes (F/B) is higher, clusters of potentially pathogenic bacteria (such as Catonella, Catonella, and Mycoplasma) are more numerous, the abundance of resistance genes is higher, and the abundance of metabolic functions is increased. The dynamic changes of the gut microbiota also played an important role in the nutritional absorption, energy metabolism, and environmental adaptation of the kiang. Improving the rearing environment and increasing food diversity play important roles for increasing the diversity of gut microbiota, reducing the spread of potentially pathogenic bacteria, and reducing diseases. In the wild, especially in winter and in food-deficient areas, food supplementation can enhance the gut microbial homeostasis of wild animals and reduce the impact of crises. In depth studies of the gut microbial function of wildlife have important implications for improving ex situ conservation.
