Fig. 3From: Identification of biomarkers associated with the feed efficiency by metabolomics profiling: results from the broiler lines divergent for high or low abdominal fat contentHeatmap of differentially expressed plasma metabolites in the positive (A) and negative (B) ion modes. The numbers in the grid are expressed as the log10 of the plasma concentrations of metabolites. HMDB_ID is the serial number for the metabolites established by the HMDBBack to article page
