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