p value indicated the significance of paired t‐test between goats without exposure to the antibiotic receiving a MC diet during the dietary modulation experiment (NST_MC) group and goats with antibiotic treatment receiving a MC diet during the dietary modulation experiment (ST_MC) group.
p value indicated the significance of paired t‐test between goats without exposure to the antibiotic receiving a LC diet during the dietary modulation experiment (NST_LC) group and goats with antibiotic treatment receiving a LC diet during the dietary modulation experiment (ST_LC) group.
*indicated the p value <.05
