Genus level redundancy analysis showing gut microbiota composition affected by probiotic supplementation and flock arearing conditions. a). Overall community composition of gut microbiota between probiotic supplemented and control flocks. b). Community composition of gut microbiota affected by flock age and probiotic supplementation. c). Community composition of gut microbiota when the birds were sampled from a rearing (Rear) and production (Prod) farms. d). Community composition of gut microbiota affected by diet regimen. Within each treatment group, “C” refers to control, while “P” refers to the probiotic supplemented flocks. As per feed management guidelines of Hy-Line International, a different type of feed was introduced at week 1 (starter), week 7 (grower), week 13 (developer), week 15 (pre lay) and week 18 (peak lay) of flock age
