“…Bacteroidetes was the most abundant phylum followed by Firmicutes in both TWAs and NPDDs, constituting more than 80% of the total bacteria content. This has been confirmed by former studies on intestinal microbial diversity in mammals [15][16][17], as these microorganisms facilitate the digestion of cellulose and hemicellulose in the diet [18]. The relative abundance of Bacteroidetes and Firmicutes in TWAs was significantly higher than in NPDDs, indicating that the cellulose and hemicellulose decomposition capacity was stronger in TWAs than in NPDDs under similar forage nutritional composition.…”

Background: Tibetan wild asses are the only wild species of perissodactyls on the Qinghai-Tibetan Plateau, and appears on the International Union for Conversation of Nature (IUCN) 2012 Red List of threatened species. The gut microbiota has a great effect on the health and nutrition of the host, however, scant research is available on the characteristics of their intestinal microbiota. Therefor, understanding the gut microbita composition and function of TWAs can provide a theoretical for the situ conservation of wild animals in the future. Results: To characterize its composition and function, we analyzed the intestinal microbiota of wild asses and domestic donkeys by high-throughput sequencing of the 16s rDNA regions. No significant difference in alpha diversity was detected between these two groups. Beta diversity showed that the bacterial community structure of wild asses was acutely different from domestic donkeys. At the phylum level, the two dominant phyla of Bacteroidetes and Firmcutes in wild asses were significantly higher than that in domestic donkeys. At the genus level, Ruminococcaceae_NK4A214 , Phascolarctobacterium , Coprostanoligenes_group , Lachnospiraceae_XPB1014_group and Akkermansia in wild asses were significantly higher than domestic donkeys. Moreover, statistical comparisons showed that 40 different metabolic pathways exhibited significant differences . Among them, 29 pathways had richer concentrations in wild asses than domestic donkeys, mainly amino acid metabolism, carbohydrate metabolism, and energy metabolism. Of note, network analysis showed that wild asses harbored a relatively more complex bacterial network than domestic donkeys, possibly reflecting the specific niche adaption of gut bacterial communities through species interactions. Conclusions: Wild asses were superior to that of domestic in gut microbial community composition and function. For wild animal conservation, wild asses are more suitable to survive in wild than to be domesticated or captive. Key words: Tibetan wild asses, domestic donkeys, 16S ribosomal RNA gene, gut microbiota

“…However, Prasad and Pradhan (1990) showed higher numbers of total, amylolytic and proteolytic bacteria, but lower protozoal counts in buffalo versus sheep rumen fluid, whereas sheep rumen fluid contained microbial N (i.e., precipitable in trichloroacetic acid) in higher concentrations than buffalo. Addition of cellulose degrading bacteria or anaerobic fungi isolated from rumen liquor of sheep to a culture of buffalo rumen fluid did not affect fiber digestibility (Sahu et al, 2003;Paul et al, 2004), showing that although some microbial species are host-specific (Sahu and Kamra, 2002), likely differences between buffaloes and sheep in their microbial populations do not have an effect on extent of feed degradation in the rumen.…”

“…Consumption of nitrogen-rich forages such as sedges and forbs is essential for microbial fermentation and increasing the efficiency of utilization of grasses (Long et al, 1999). This is especially true in the case of free-ranging animals in less productive environments, because here they have to rely heavily upon the efficiency of the microbial activities of the gastro-intestinal tract for extracting the maximum possible nutrients from poor quality feeds (Sahu and Kamra, 2002).…”
