Abstract: This study was carried out to compare gut microbial community composition, diversity, and function with and without microbiota transplantation in a newly-hatched chick model. Two hundred and forty newly-hatched Arbor Acre male broilers were assigned randomly to either a microbiota transplantation group or a control group ( n = 120; 6 replicates per group, and 20 broilers per replicate). Both groups were fed a basal diet that met all nutritional requirements, composed of corn, soybean meal, cottonseed meal, vitamins, and minerals. The microbiota transplantation group was inoculated with the microbiota from the ceca of healthy adult chicks on day 1 and 2, respectively, over a trial period of 42 d. For both groups, the numbers of total bacteria, Lactobacillus and Escherichia coli , operational taxonomic unit partitioning and classification, taxonomic composition, comparative microbiota, and key bacterial species were identified by a 16S rRNA sequencing analysis. The results showed that Aestuariispira , Christensenella , Fervidicella , Gracilibacter , Haloferula , Mycoplasma , Novispirillum, and Pantoea were more abundant ( p < 0.05) in the microbiota transplantation group than those in the control group. This indicates that microbiota transplantation could directly influence the abundances of specific bacterial taxa in the ileum and cecum of broilers. These findings provide insight into the modulation of gut health for patients with abnormal bowel function, which should be of great interest to researchers in the area of gastroenterology, applied microbiology, and animal sciences.
