The present study aimed to compare the nutritional effects of cholesterol, bile acids, and combination of cholesterol with bile acids in plant-based diets on juvenile genetically improved farmed tilapia(GIFT;Oreochromis niloticus). The isonitrogenous(321 g/kg crude protein) and isolipidic(76 g/kg crude fat) diets(Con diet) were based on plant protein sources, which included corn gluten meal, soybean meal, cottonseed meal and rapeseed meal. The Con diet was supplemented with 12 g/kg cholesterol(CHO diet), 0.2 g/kg bile acids(BAs diet), a combination of 12 g/kg cholesterol and 0.2 g/kg bile acids(CHO-BAs diet),respectively. Each diet was fed to three tanks in an indoor recirculating aquaculture system for 9 *** showed that compared to the Con group, fish had a higher weight gain rate, hepatosomatic index,and a lower feed conversion ratio in the CHO-BAs group. The highest levels of whole-fish fat and ash were found in the Con group. Serum parameters, including activities of alanine aminotransferase(ALT) and aspartate transaminase(AST), along with levels of glucose(GLU) and triglyceride(TG) except for total cholesterol(TCHO), were lower in the CHO, BAs, and CHO-BAs groups than those in the Con group(P <0.001). Histological examination revealed that fish in the Con group exhibited severe hepatocyte vacuolization and diminished hepatocyte proliferation. Gene expression analysis indicated that the transcriptional levels of bile acid metabolism-related genes(including fxr, fgf19, bsep) were up-regulated in the CHO-BAs group(P < 0.05), whereas cholesterol metabolism-related genes(acly and hmgcr) were downregulated in both CHO and CHO-BAs groups(P < 0.001). Moreover, UPLC-MS/MS analysis revealed that the higher taurine-conjugated bile acids(T-BAs), followed by free bile acids(Free-BAs) and glycine(G-BAs)were determined in tilapia bile. Among these, taurochenodeoxycholic bile acid was the predominant bile acid. Dietary bile acids supplementation also increased the pr
