¹BW₁₁ and BW₂₃ = body weight at 11 and 23 wk of age, ADG_11–23 = average daily gain between 11 and 23 wk of age; ADFI_11–23 = average daily feed intake between 11 and 23 wk of age; FCR_11–23 = feed conversion ratio between 11 and 23 wk of age; ST₂₃ = skin temperature at 23 wk of age; RT₂₃ = rectal temperature at 23 wk of age; OTU = operational taxonomic unit.

²Residual standard deviation from an ANOVA model accounting for the enterotype (E), the climate (C), the sex type (S), the sire family (F), the batch, and the interactions E × C and E × S.

³Significant effects (P < 0.05). Batch effect was significant for all traits and is not reported in the table.

^a–cLeast squares means within a row with different superscripts significantly differ (P < 0.05).
