Pathway distribution of differential metabolites in the portal vein of NBW and IUGR pigs. Differential metabolites between NBW and IUGR pigs were used to analyzes the pathways. Node radius size and importance (X axis) reflects the pathway impact values calculated using betweenness centrality, which takes into consideration the global network structure and measures the number of shortest paths going through metabolites within the node. Node color and direction (Y axis), however, is based on the calculated P value of the enrichment analysis. Labeled pathways were up-regulated in IUGR pigs. NBW, normal birth weight; IUGR, low birth weight
