Combined analysis of 16S rRNA sequencing and metabolomics reveals the growth-promoting mechanism of compound probiotics in zig-zag eel (Mastacembelus armatus)

A total of 1500 three-month-old healthy M. armatus were randomly divided into 5 groups (4 replicates per treatment): CON (control group), BC (Bacillus cereus G1-11 group), EA (Exiguobacterium acetylicum G1-33 group), MIX (the compound probiotics group), PC (Commercial probiotics group), and the feeding period was 8 weeks. In order to carry out microbial analysis, 12 intestinal contents of each group were sampled. Each 3 tails were mixed.
