Predictive metagenomics showing differences in the function of colonic microbiota in weaned piglets with normal birth weight (NBW) and intrauterine growth retardation (IUGR) using PICRUSt analysis at level 3 (n = 11 or 12). A represents N_c vs. I_c groups; B represents N_c vs. N_b groups; C represents I_c vs. I_b groups; D represents N_b vs. I_b groups. N_c NBW group (NBW piglets fed a basal diet), I_c IUGR group (IUGR piglets fed a basal diet), N_b NBW + BA group (NBW piglets fed a basal diet supplemented with 400 g/t BA), I_b IUGR + BA group (IUGR piglets fed a basal diet supplemented with 400 g/t BA)
