Abstract Gastrointestinal microbiome plays an important role in animal metabolism, immune system and pathology associated with health and disease. Many wild slow lorises were confiscated from illegal trade into captivities and experienced a range of changes in living environment and diet. Microbiome analysis contributes to improving captive management by identifying the alteration in their gastrointestinal microbial communities and aiding in determining the factors affecting the health of captive slow lorises. The fecal samples of eighteen Bengal slow lorises (Nycticebus bengalensis) were used to compare gut microbiota from four rescue centers located in Dehong, Gejiu, Nanning and Puer cities of China. The results showed a significant site-dependent difference in microbial community diversity. Similar to other Lorisinae species, the Phyla including Bacteroidetes, Firmicutes and Proteobacteria dominated their gut microbiome composition. The Gejiu group exhibited a higher overall diversity and the unique OTUs, which is resulted from long-term isolated husbandry and heavy human disturbances. The scarcity of gums in the captive diet was likely to cause a lower abundance of Prevotella associated with soluble fiber degradation. The variation of intestinal microbiota in different environments highlights the necessity to improve feed preparation and husbandry management for the captive Bengal slow lorises.
Introduction Many non-human primates around the world are currently endangered due to habitat encroachment, plummeting populations and illegal trade [1, 2]. Conservation strategies include anti-poaching regulations, habitat restoration, providing sanctuaries, captive breeding and reintroduction.

Integrated solutions at macro- and micro-ecological levels are involved in these strategies [3]. As an emerging suite of novel tools, microbiome analyses have great potential for supporting conservation efforts [4]. Trillions of microbes inhabiting the gut of non
