Dietary pectin caused great changes in bile acid profiles of Pelteobagrus fulvidraco

To reveal the impact of dietary fiber (DF) on the bile acid (BA) profiles of fish, yellow catfish ( Pelteobagrus fulvidraco ) were fed a diet containing 300 g kg −1 dextrin (CON diet, control) or pectin (a type of soluble DF, PEC diet) for 7 days, and then the BA profiles were analyzed by UHPLC-MS/M...

Zusammenfassung:To reveal the impact of dietary fiber (DF) on the bile acid (BA) profiles of fish, yellow catfish ( Pelteobagrus fulvidraco ) were fed a diet containing 300 g kg −1 dextrin (CON diet, control) or pectin (a type of soluble DF, PEC diet) for 7 days, and then the BA profiles were analyzed by UHPLC-MS/MS. A total of 26 individuals of BAs were detected in the fish body, with 8, 10, 14, and 22 individuals of BAs detected in the liver, serum, bile, and hindgut digesta, respectively. The conjugated BAs (CBAs) of fish were dominated by taurine CBAs (TCBAs). The concentrations of free BAs (FBAs) and the value of FBAs/CBAs in the bile of fish fed the PEC diet were nearly 5 and 7 times higher, respectively than those in fish fed the CON diet. The value of glycine CBAs/TCBAs in the liver, serum and bile of fish fed the PEC diet was significantly lower, and in the hindgut digesta was higher than that of fish fed the CON diet ( P
