¹All data are expressed as the mean ± SEM (n = 11/group) of the percentage of domain bacteria at taxonomic levels (phylum and genus). Data were analyzed using one-way ANOVA. p-values between control and FMT chicks were obtained using the t-test. Values between groups are significantly different (^*p ≤ 0.05, ^**p ≤ 0.01, ^***p ≤ 0.001).
