  • effects of dietary biotin on growth performance and fatty acids metabolism in blunt snout bream megalobrama amblycephala fed with different lipid levels diets
    Aquaculture, 2017
    Co-Authors: Yu Qian, Dongsen Cai, Wenbin Liu
    Abstract:

    Abstract A 2 × 2 factorial design was conducted to elucidate the effect of dietary biotin on growth performance, body composition, tissue lipid content and lipid metabolism related genes expression of blunt snout bream, Megalobrama amblycephala fed with different dietary lipid levels. Juvenile fish (average initial weight: 36.0 ± 1.0 g) were fed with diets containing two lipid levels (5% and 11%) and two biotin levels (0.06 mg kg − 1 and 2.50 mg kg − 1 ) for 8 weeks, respectively. Specific growth rate (SGR), Hepatosomatic Index (HSI), mesenteric fat Index (MFI), hepatopancreas lipid, total triacylglycerol (TG) and cholesterol (TC) contents, plasma TG and muscle TG contents were significantly ( P P P P P P P

  • effects of dietary choline supplementation on growth performance and hepatic lipid transport in blunt snout bream megalobrama amblycephala fed high fat diets
    Aquaculture, 2014
    Co-Authors: Dingdong Zhang, Chunnuan Zhang, Guangzhen Jiang, Wenbin Liu
    Abstract:

    Abstract In this study, we elucidated the choline metabolic pathways and its effects on growth and hepatic lipid transport in blunt snout bream, Megalobrama amblycephala. Fish were fed six experimental diets containing three lipid levels (5%, 8%, and 11%) and two choline supplementation levels (1200 and 1800 mg kg− 1) for 8 weeks. After the feeding trial, viscera/body ratio, Hepatosomatic Index, plasma aspartate aminotransferase activities, and plasma triglyceride and cholesterol contents as well as liver lipid content all increased significantly (P

  • effects of dietary carbohydrate lipid ratios on growth performance body composition and glucose metabolism of fingerling blunt snout bream megalobrama amblycephala
    Aquaculture Nutrition, 2013
    Co-Authors: Yu Wang, Wenbin Liu, Guangzhen Jiang, Jiaojiao Zhu
    Abstract:

    This study aimed to investigate the optimum dietary carbohydrate/lipid (CHO/L) ratio for fingerling blunt snout bream Megalobrama amblycephala (average initial weight: 6.61 ± 0.03 g). Six isonitrogenous and isoenergetic diets were formulated to contain various CHO/L ratios ranging from 1.62 to 24.20. Each diet was tested in four replicates for 10 weeks. Specific growth rate (SGR), feed conversion ratio and nitrogen and energy retention all improved significantly (P   0.05) as dietary CHO/L ratios ranged from 2.45 to 5.64. Hepatosomatic Index increased significantly (P   0.05) among all the treatments, while liver glycogen content increased significantly (P < 0.05) with increasing CHO/L ratios. High dietary carbohydrate enhanced the activities of liver hexokinase, pyruvate kinase and glucose-6-phosphate dehydrogenase but did not induce hyperglycaemia. Based on the second-order polynomial regression analysis of SGR, the optimal dietary carbohydrate and lipid contents for fingerling blunt snout bream were 291.7 and 81.4 g kg−1, respectively, with a corresponding dietary CHO/L ratio of 3.58.

  • temporal changes of plasma vitellogenin vtg alkaline labile protein phosphorus alpp calcium ca glutamate pyruvate transaminase gpt and Hepatosomatic Index hsi in the estradiol 17 beta administered immature rockfish sebastes schlegeli

    Abstract:

    Temporal changes of plasma vitellogenin (VTG), alkaline-labile protein phosphorus (ALPP), calcium (Ca), glutamate pyruvate transaminase (GPT) and Hepatosomatic Index (HSI) were examined in the -administered immature rockfish, Sebastes schlegeli. Fish were intraperitoneally injected with (5 ㎎/kg B.W.) in 70% ethanol and then plasma were extracted at 0, 1, 3, 6, 9, 12 and 15 days. VTG band was detected at a molecular weight position of about 170 kDa on Day 3 in SDS-PAGE. This band became more distinct at 6 days but its was gradually thinned with time-course, and not detected at 15 days. Plasma ALPP and Ca increased suddenly at 1 day and the highest concentrations were detected at 6 days and then these concentrations decreased gradually with time-course. ALPP and Ca concentrations at 15 days after E2 administration were very similar to that before E2 administration. GPT was increased at 1 day and higher GPT was detected at 3 days. However, GPT was gradually decreased with time-course. GPT and HSI at 15 days after E2 administration were also very similar to that before E2 administration. HSI was also increased at 1 day and the highest value was detected at 3 days and then gradually decreased with time-course. These results suggest that plasma ALPP, Ca, GPT and HSI could be utilized as a biomarker of exogenous E2 exposure in coastal ecosystem, because the changes of ALPP, Ca, GPT and HSI after E2 administration are very similar to that of VTG
