The abundance of gut microbiota at the genus level is affected by probiotic supplementation. a). Overall relative abundance levels of microbial communities affected by probiotic. b). Relative abundance levels of microbial communities in the rearing phase of layer between the control (Rear_Control) and probiotic supplemented (Rear_Probiotic) flocks. c). Relative abundance levels of microbial communities in the early production phase of layer between the control (Prod_Control) and probiotic supplemented (Prod_Probiotic) flocks. Relative abundance levels (in log₂ cumulative sum scaling) was calculated in Calypso software and the data were visualised in GraphPad Prism v.8.0.0. Asterisks (*, ** and ***) show P values at 0.01, 0.001 and 0.0001, respectively
