“…In the present research, group H has the highest α-diversity of fecal microbiota, this might indicate that the high protein of Group H has caused certain stress to the FMD, so that the intestinal bacteria have to make changes to cope with this stress. Firmicutes and Bacteroidetes had the hightest relative abundance in this study, which was consistent with the previous studies ( Hu et al, 2017 ; Sun et al, 2020 ; Li et al, 2021 ; Su et al, 2022 ). Whereas the abundance of Firmicutes increased, and Bacteroidetes decreased with the increasing of dietary CP.…”

It is necessary to assess the appropriate dietary protein level of the forest musk deer (FMD), as nutritional needs are unclear. The microbiome in gastrointestinal tracts plays an important role in regulating nutrient utilization, absorption and host growth or development. Thus, we aimed to evaluate growth performance, nutrient digestibility and fecal microbiome of growing FMD supplied with different protein levels of diets. Eighteen 6-month-old male FMD with an initial weight 5.0 ± 0.2 kg were used in a 62-day trial. The animals were randomly distributed to three groups, the dietary crude protein (CP) level was 11.51% (L), 13.37% (M), and 15.48% (H). The results showed that the CP digestibility decreased as dietary CP level increased (p < 0.01). Compared with group L and H, FMD in M group has higher average daily gain, feed efficiency and neutral detergent fiber digestibility. For the fecal bacterial community, the percentage of Firmicutes was increased, Bacteroidetes was decreased and the diversity of microbiota significantly reduced (p < 0.05) with the increasing of dietary protein. The proportion of Ruminococcaceae_005, Ruminococcaceae_UCG-014 and uncultured_bacterium_f_Lachnospiraceae were significantly increased wtih rising CP, the proportions of Bacteroides and Rikenellaceae_RC9_gut_group were significantly decrease nevertheless at the genus level. The higher abundance of f_Prevotellaceae and g_Prevotellaceae_UCG_004 were found at M group by LEfSe analysis. The relative abundance of uncultured_bacterium_f_Ruminococcaceae was positively correlated with the average daily gain and feed conversion ratio (p < 0.05), whereas Family_XIII_AD3011_group was negatively correlated with feed conversion ratio (p < 0.05). The UPGMA tree showed L and M groups were closer in clustering relationship, while H group was clustered separately into a branch, which indicated that the bacterial structure had changed greatly with protein level increased from 13.37 to 15.48%. Overall, our results indicated that the optimum dietary CP for the growing FMD was 13.37%.

“…Food resources can change over temporal scales. For the deer population, sufficient and diverse fresh plant-derived food is available in the grassy season; however, food resources and choices are relatively limited in the withering season due to severe weather conditions ( Hu et al, 2018 ; Li et al, 2022 ; Su et al, 2022 ; You et al, 2022 ). Dramatic seasonal variations in gut microbiota compositions are observed in deer species ( Figure 1A ).…”

“…In contrast, the relative abundance of Firmicutes and the Firmicutes / Bacteroidetes (F/B) ratio are higher in the withering season than in the grassy season. Firmicutes can digest and absorb nutrients by degrading diverse substances, and the gut microbiota with a high F/B ratio can exhibit a higher fermentation efficiency and thus obtain more energy from food ( Chevalier et al, 2015 ; Su et al, 2022 ). Moreover, a high F/B ratio can promote fat deposition in the host ( Su et al, 2022 ), which is important for adapting to the cold withering season.…”

“…Beneficial microbe administration-based microbiota manipulation approaches mentioned below have consequently been developed and have shown promising benefits in animal breeding and raising practices ( Anee et al, 2021 ). With such rapid developments in omics technologies and their contributions to microbiota decryption and application, several omics-based studies have been conducted for analyzing the gut microbiota of deer species, particularly six species belonging to the family Cervidae [sika deer ( C. nippon ) ( Guan et al, 2017 ; Wang et al, 2022 ), Père David’s deer ( E. davidianus ) ( Zhang et al, 2018 ; Sun et al, 2019 ), red deer ( C. elaphus ) ( Menke et al, 2019 ; Wang et al, 2019 ), white-lipped deer ( C. albirostris ) ( Li J. G. et al, 2017 ; Li et al, 2022 ; You et al, 2022 ), Siberian roe deer ( Capreolus pygargus ) ( Liu J. et al, 2019 ), and white-tailed deer ( Odocoileus virginianus )] ( Delgado et al, 2017 ; Minich et al, 2021 ) and three species belonging to the genus Moschus [alpine musk deer ( M. chrysogaster ) ( Sun et al, 2020 ), Siberian musk deer ( M. moschiferus ) ( Su et al, 2022 ), and forest musk deer ( M. berezovskii )] ( Li Y. et al, 2017 ). The predominant bacterial phyla in these deer species were found to be Firmicutes , Bacteroidetes , Proteobacteria , and Actinobacteria ; these findings are consistent with previous findings regarding the gut microbiota of ruminants ( Tanca et al, 2017 ).…”

Thousands of microbial species inhabiting the animal gut, collectively known as the gut microbiota, play many specific roles related to host nutrient metabolism and absorption, immune regulation, and protection from pathogenic bacteria. Gut microbiota composition is affected by several internal and external factors, such as the host genotype, dietary intake, breeding environment, and antibiotic exposure. As deer species are important members for maintaining ecosystem balance, understanding the effects of multiple factors on the gut microbiota of deer species, particularly endangered ones, is crucial. In this review, we summarize and discuss the factors that significantly affect the gut microbiota of deer and present the impacts of these factors on microbial composition. In particular, we focused on the changes in gut microbiota due to dietary differences under different conditions, including seasonal changes, different geographical locations, and captivity, as well as weaning and pathogen disturbance. Understanding the correlations between gut microbiota composition and its driving factors is important for evaluating and improving the captive breeding environment for better conservation of endangered deer species, and reintroducing wild deer populations in the future.
