As an important part of biological rhythm, circadian rhythm plays a crucial role in the microbiota composition of laying hens. The purpose of this experiment was to investigate the circadian rhythm of fecal microbiota in laying hens.. Circadian rhythm of the fecal microbiota in laying hens

This study has shown that the time of defecation was among the important factors to influenced the composition and diversity of the fecal microbiota community. These results provides references for further exploring the circadian rhythm of gut microbiota in laying hens.
