Overall gut microbiota composition at phylum level affected by probiotic supplementation in rearing and production phases of hens. a). Microbial abundance (%) of the control flock (Rear_Control) in the rearing phase. b). Microbial abundance (%) of the probiotic flock (Rear_Probiotic) in the rearing phase. c). Microbial abundance (%) of the control flock (Prod_Control) in the production phase. d). Microbial abundance (%) of the probiotic flock (Prod_Probiotic) in the production phase. For percent calculation of microbial abundance at the phylum level, total sum scaling normalised but untransformed data obtained from Calypso software were visualised in Excel 2016 and the panel graphs were prepared in Graphpad prism v. 8.0.0
