    Bioavailability is critical in ensuring bioefficacy of ginger compounds, which have not been studied in chicks. In this study, day-old chicks were treated with ginger root extract at 0.0, 0.4, 0.8, 1.5, and 3.0% for 42 days. The gingerols and shogaols in chick samples were analyzed by liquid chromatography-mass spectrometry. The primary phase-I metabolic pathway for gingerols and shogaols was the reduction of ketone groups into hydroxyl groups. Shogaols were also metabolized through thiol conjugation and hydrogenation of double-bond pathways. Within the bloodstream, gingerols and their metabolites predominantly existed as glucuronidate or sulfate conjugates. However, the levels of the free form and conjugates were comparable for shogaols. In breast meat, the quantities of both the free form and conjugates for all compounds were similar. In plasma, more than 50% of absorbed 6-gingerol (6G) and 90% of absorbed 6-shogaol underwent reduction to their respective metabolites. However, in breast meat, the percentage of reduction for absorbed 6G was less than 50%, and for absorbed 6-shogaol, it was less than 60%. Ginger compounds were absorbed into chick plasma ranging from 1.4 to 8.5 μg/mL and breast meat ranging from 7.1 to 114.6 μg/100 g across the 0.4-3.0% dose range in a dose-dependent manner.
