Abstract: 【Objective】 The purpose of this experiment was to explore the structural composition and diversity of fecal flora in young suckling and adult female camels, and provide an important basis for healthy development of young camels.【Method】 12 adult female camels with 6-7 years old and similar physical condition, and 12 young suckling female camels with similar birth date (3 months old) were selected.The fresh fecal samples were collected by rectal fecal sampling method for V3-V4 region sequencing of 16S rDNA of fecal microbiota, and the sequencing data were analyzed accordingly.【Result】 The Chao1 and Shannon indexes of fecal flora in adult female camels were significantly higher than that of young suckling camels (P<0.05).At phylum levels, the top 10 bacteria in feces of adult female and young suckling camels were Firmicutes, Bacteroidetes, Verrucomicrobia, Proteobacteria, Tenericutes, Spirochaetes, Saccharibacteria, Actinobacteria, Cyanobacteria and Fibrobacteres.But the abundance of Proteobacteria and Tenericutes in feces of young suckling camels were extremely significantly higher than that of adult female camels (P<0.01).At family levels, the top 10 bacteria in feces of adult female and young suckling camels were Ruminococcaceae, Peptostreptococcaceae, Lachnospiraceae, Clostridiaceae, Christensenellaceae, Rikenellaceae, Verrucomicrobiaceae, Bacteroidaceae, Mogibacteriaceae and Paraprevotellaceae, and the abundance of Peptostreptococcaceae and Clostridiaceae in feces of adult female camels were extremely significantly higher than that of young suckling camels (P<0.01), while the abundance of Lachnospiraceae in feces of young suckling camels was extremely significantly higher than that of adult female camels (P<0.01).At genus levels, the top 10 bacteria in feces of adult female and young suckling camels were Clostridium, Oscillospira, Ruminococcus, Clostridiaceae_Clostridium, Akkermansia, 5-7 N15, CF231, Turicibacter, Clostridiaceae-SMB53 and Treponema, and the abundance of Clostridium, Clostridiaceae_Clostridium and Turicibacter in feces of adult female camels were extremely significantly higher than that of young suckling camels (P<0.01).【Conclusion】 The fecal flora diversity of adult female camels was significantly higher than that of young suckling camels, and show more stability.The dominant species of bacteria in feces of adult female and young suckling camels were consistent at the levels of phylum, family and genus, but there were difference in abundance.
