A 10-week feeding trial was conducted to investigate the beneficial effects of bile acids (BAs) on hepatic health status in tongue sole (Cynoglossus semilaevis). Three experimental diets were prepared with different levels of BA inclusion in the commercial basal diet: control group (CT: 0 mg/kg basal diet), low-level group (BA1: 300 mg/kg basal diet), and high-level group (900 mg/kg basal diet). At the end of the feeding trial, growth performance and survival rate were measured, as well as numerous physiological and biochemical parameters of the liver, including four hepatic function indices, five antioxidant indices, five lipid metabolism parameters, and three digestive enzyme activities. Moreover,the mRNA expression levels of three growth-related genes and three immune-related genes in the liver were assayed. Results showed that growth performance and survival were substantially improved in both low- and high-level BA inclusive groups. Further, the tested liver physiological and biochemical parameters combined with the quantitative real-time PCR results revealed enhanced antioxidant capacity, energy metabolism, digestive ability, and immune response. Finally, these findings provide a wider spectrum of the beneficial effects of dietary BAs on liver health in tongue sole.

為研究膽汁酸對半滑舌鰨（Cynoglossus semilaevis）肝臟健康狀況的有益影響，進行了為期10周的喂養試驗。在商業基礎日糧中製備了三種含有不同水平膽汁酸的試驗日糧：對照組（0 mg/kg）、低水平組（300 mg/kg）和高水平組（900 mg/kg）。喂食試驗結束後，測量生長性能和存活率,以及肝臟的各項生理生化參數，包括四項肝功能指標、五項抗氧化指標、五項脂代謝參數和三項消化酶活性。此外，還檢測了肝臟中三個生長相關基因和三個免疫相關基因的mRNA表達水平。結果表明，低水平膽汁酸組和高水平膽汁酸組的生長性能和存活率均顯著提高。此外，檢測的肝臟生理生化參數結合實時定量PCR結果顯示：抗氧化能力、能量代謝、消化能力和免疫反應增強。最後，這些發現提供了更廣泛的日糧添加膽汁酸對舌鰨肝臟健康的有益影響。
