Abstract:
Objectives: The giant panda takes low nutrition and high fiber bamboo as the main food , but its digestive system structure retains the characteristics of carnivores and does not have the ability to digest cellulose, so The gut microorganism of giant pandas is important for the digestion of cellulose. This study is aimed to investigate the changes of intestinal microbial structure of sub-adult giant pandas in different seasons and their inner relationship with the ability of cellulose digestion . Methods: This study used high-throughput sequencing technology to analyze the bacterial and fungal diversity of the four sub-adult giant pandas in different seasons, as well as the cellulase activity of sub-adult giant pandas in different seasons was tested. Results: Then this study investigated the gut microbial structure of sub-adult giant pandas in different seasons and its correlation with their cellulase activities. The results showed that there were significant differences in the intestinal bacteria and fungi structure and richness of sub-adult giant pandas in different seasons. The microbial structure in winter (February) was complicated and the microbial richness was relatively high. The dominant degree of bacteria in winter was significantly higher than other seasons. In autumn (November) and winter (February), the cellulase activity of sub-adult giant pandas was generally higher, and in winter was about 5 times that of other seasons. Conclusions: It was closely similar to the changes of the intestinal dominant bacteria abundance, Streptococcus, between which the correlation coefficient is 0.582. In addition, more complex intestinal microbial structures, especially fungal, are more conducive to sub-adult giant panda digestion of cellulose. In general, the evolution of intestinal microbial structure of sub-adult giant pandas in different seasons has an important impact on cellulose digestion.
