| Abstract;Two experiments were conducted to investigate the effects of ursodeoxycholic acid (UDCA) on growth performance and digestive enzyme activities of juvenile red sea bream, Pagrus major. In experiment 1 for growth study, duplicate groups of the juveniles of about 9.01 g in initial body weight were fed a UDCA diet (containing 0.025% UDCA) and a control diet (without UDCA) for 6 weeks. The weight gain of the juveniles fed the UDCA diet tended to be higher than that of the control diet. Total lipids and triglycerides of the whole body were significantly higher in the UDCA-diet group than the control. In experiment 2 for enzyme study, triplicate groups of the juveniles of about 9.11 g body weight were fed the UDCA and control diets for 6 weeks, digestive organs were collected every 2 weeks and enzyme (.ALPHA.-amylase, lipase and protease) activities were assayed. The activity of .ALPHA.-amylase for the juveniles fed the UDCA diet tended to increase with the lapse of holding time. But lipase and protease activities of the juveniles fed UDCA diet, were significantly higher than those fed the control diet. The findings of this study indicate that UDCA may promote lipid utilization and nutrient retention by increasing digestive enzyme activities of red sea bream juveniles. (author abst.) |
