To evaluate how eucalyptus leaf polyphenol extract (EPE) affects chicken meat color and taste, we added different levels of EPE (0%, 0.06%, 0.09%, and 0.12%) to chicken feed. The redness (a* value) and the myoglobin content of breast muscle in EPE group were remarkably higher. Furthermore, the guanosine monophosphate, histidine, and glycine muscle contents were also enhanced. Transcriptome analysis showed that 10 candidate genes related to meat quality were affected by EPE treatment. The identified genes, with functions critical to chicken meat color and taste, will help to determine the molecular mechanisms of EPE.
