Predictive metagenomics showing differences in function between intrauterine growth retardation (IUGR) pigs and normal birth weight (NBW) pigs in the ileum using PICRUSt analysis (level 3). The data presented are obtained from 10 animals in each group (n = 10). II and IN represent samples obtained from the ileum of IUGR pigs and NBW pigs, respectively. Twenty-five, 50, and 100 represent 25, 50, and 100 kg BW. LEfSe analysis was used to identify potentially enriched pathways. Pathways with LDA scores ≥2 in the 25 kg BW group (a), and LDA scores ≥3 in the 50 (b) and 100 (c) kg BW groups are shown
