Clostridium butyricum is known as a butyrate producer and a regulator of gut health, but whether it exerts a beneficial effect as a dietary supplement via modulating the intestinal microbiota remains elusive. This study investigated the impact of C. butyricum on the fecal microbiota composition and their metabolites 14 and 28 days after weaning with 10 g/kg dietary supplementation of C. butyricum. Dynamic changes of microbial compositions showed dramatically increasing Selenomonadales and decreasing Clostridiales on days 14 and 28. Within Selenomonadales, Megasphaera became the main responder by increasing from 3.79 to 11.31%. Following the prevalence of some acetate producers (Magasphaera) and utilizers (Eubacterium-hallii) at the genus level and even with a significant decrease in fecal acetate on day 28, the present data suggested that C. butyricum influenced microbial metabolism by optimizing the structure of microbiota and enhancing acetate production and utilization for butyrate production.
