Effects of Different Quality Fish Meal on Growth Performance, Feed Utilization and Liver Antioxidant Capacity of Juvenile Yellow Catfish ( Pelteobagrus fulvidraco)
摘要
Abstract
A 10-week feeding trial was conducted to evaluate the effects of different quality fish meal on growth performance, feed utilization and liver antioxidant capacity of juvenile yellow catfish ( Pelteobagrus ful-vidraco). A total of 270 juvenile yellow catfish with an initial body weight of (0.90±0.02) g were randomly divided into 3 groups with 3 replicates per group and 30 yellow catfish for each replicate. Three iso-nitrogenous and iso-lipid diets were formulated to contain different fish meal, such as imported fish meal ( Peru steam fish meal) , local fish meal ( fish meal produced in Rongcheng of Shandong) and mixed fish meal ( imported fish meal:local fish meal=1:1 ) , respectively. The results showed that weight gain rate ( WGR ) and specific growth rate ( SGR) in the local fish meal group were the highest, those in the mixed fish meal group took sec-ond place, and those in the imported fish meal group were the worst, there were signifant differences among 3 groups ( P<0. 05 ) . There were no significant differences in feed efficiency ( FE ) , protein efficiency ratio ( PER) , condition factor ( CF ) , hepatosomatic index ( HSI ) and viscerosomtic index ( VSI ) of juvenile yellow catfish among all groups ( P>0.05) . Serum total cholesterol ( TC) conent in the mixed fish meal group was the highest, and significantly higher than that in the imported fish meal group ( P<0.05);serum high den-sity lipoprotein ( HDL-C) content in the imported and mixed fish meal groups was significantly higher than that in the local fish meal group ( P<0.05); serum low density lipoprotein ( LDL-C) content in the imported fish meal group was significantly lower than that in the mixed and local fish meal groups ( P<0.05) . Total protein ( TP) , glucose ( GLU) and triglyceride ( TG) contents and alkaline phosphatase ( AKP) activity in serum were not significantly different among all groups ( P>0.05) . Fish fed the diet containing imported fish meal had higher superoxide dismutase ( SOD ) , catalase ( CAT ) and glutathione peroxidase ( GSH-Px ) activities and malondialdehyde ( MDA) content in liver than fish fed the diet containing local fish meal ( P<0.05); howev-er, there was no significant difference in liver total antioxidant capacity ( T-AOC ) among all groups ( P>0.05) . Muscle polyunsaturated fatty acid ( PUFA) content in mixed fish meal group was significantly higher than that in the imported and local fish meal groups (P<0.05), but muscle saturated fatty acid (SFA) and monounsaturated fatty acid (MUFA) contents were not significantly different among all groups (P>0.05). Thus, relative to imported fish meal, the diet supplemented with local fish meal can improve growth perform-ance and liver antioxidant capacity of juvenile yellow catfish under this experimental conditions;feeding the di-et containing the mixed fish meal can help to increase accumulation of PUFA in muscle.关键词
