Chicken serum metabolic profiles based on QC samples. A Venn diagram of all metabolites identified in the four detection modes. The same metabolites were detected by multiple modes with a count of 1. B Venn diagram of endogenous metabolites identified in the four detection modes. The same metabolites were detected by multiple modes with a count of 1. C Identification of metabolites using three classes of database. SD, Standards Database; KD, KEGG Database; ID, Intergrated Database; T, Total metabolites; E, Endogenous metabolites. D Classification of all metabolites
