Fig. 6From: Lactation-related metabolic mechanism investigated based on mammary gland metabolomics and 4 biofluids’ metabolomics relationships in dairy cowsFunctional enrichment of the different pathways identified by shared metabolites in the rumen fluid, serum, milk and urine. The bar chart size indicates the pathway enrichment, and the color density represents the difference. Pathways with a larger size and darker red color are the more enriched pathwaysBack to article page
