Comparison of intestinal microbiota maturation among the three regimens. a Contributions of different factors on chicken gut microbiota variation. The PERMANOVA test was used for all samples based on Meta-Storm distance. Group is the largest contributor (F = 3.83, p = 0.002) for broiler gut microbiota variation followed by time point (F = 2.01, p = 0.048). b Tenfold cross-validation error as a function of the number of input genera-level taxa used to regress against the age of chicken in the training set, in the order of variable importance. c The top 16 age-discriminatory bacterial taxa as identified via the Random Forest regression. These taxa were considered as bacterial biomarkers that are able to differentiate the maturity of broiler intestinal microbiota from birth to slaughter. The temporal patterns of intestinal maturation were compared among the control group (d), the antibiotic group (e), and the probiotic group (f), which revealed that probiotics accelerated yet antibiotics delayed intestinal microbiota maturation
