Influences of Oxidized Fish Oil on Growth Performance and Antioxidant Indexes of Yellow Catfish (Pelteobagrus fulvidraco) and the Use of Arginine as an Intervention Measure
摘要
Abstract
This experiment was conducted to investigate the influences of dietary oxidized fish oil ( OF) on the growth performance, body composition, serum biochemical indexes and serum, liver antioxidant indexes of ju⁃venile yellow catfish ( Pelteobagrus fulvidraco) , and the intervention of arginine ( Arg) on them. A total of 600 healthy juvenile yellow catfish with an initial body weight of (4.41±0.05) g were randomly divided into 6 groups with 4 replicates of 25 fish. During 56 d feeding trial, the fish were fed six diets containing 2.5% fresh fish oil ( FF group) , 1.5% fresh fish oil+1.0% oxidized fish oil ( FO1 group) , 0.5% fresh fish oil+2.0% oxi⁃dized fish oil (FO2 group), 2.5% fresh fish oil+0.48% L⁃arginine hydrochloride (FFA group), 1.5% fresh fish oil+1.0% oxidized fish oil+0.48% L⁃arginine hydrochloride (FOA1 group), 0.5% fresh fish oil+2.0%oxidized fish oil+0.48% L⁃arginine hydrochloride ( FOA2 group) , respectively. The results showed that among FF, FO1 and FO2 groups, the weight gain rate, specific growth rate and protein deposition rate of yellow cat⁃fish showed a downward trend, but feed conversion ratio and feeding rate were reversed. All of them reached the extreme value in the FO2 group, and the difference reached a significant level compared with FF and FO1 groups ( P<0.05) . While addition of Arg to the oxidized fish oil diets, no significant differences were found in above indexes among FFA, FOA1 and FOA2 groups (P>0.05), but the weight gain rate was increased by 3.0% ( FOA1 group vs. FO1 group) and 9.9% ( FOA2 group vs. FO2 group) , respectively. Two⁃factor vari⁃ance analysis results showed that oxidized fish oil had significant influences on weight gain rate and feeding rate ( P<0.05) , and oxidized fish oil and Arg had significant interactions on specific growth rate, protein deposi⁃tion rate and feed conversion ratio ( P<0.05) . The hepatosomatic index in FO1 group was significantly lower than that in FF group ( P<0.05) , and the intestinesomatic index in FO2 group was significantly decreased com⁃pared with FFA and FOA2 groups ( P<0.05) . Oxidized fish oil and Arg had a significant interaction on hepato⁃somatic index ( P<0.05) . The crude lipid content of whole body in FOA1 group was significantly lower than that in FO1 group ( P<0. 05 ) . Among FF, FO1 and FO2 groups, the serum total antioxidant capacity ( T⁃AOC) showed a downward trend with oxidized fish oil addition increasing, and showed a significant differ⁃ence between FF and FO2 groups ( P<0.05) . While addition of Arg to the oxidized fish oil diets, the serum T⁃AOC was increased by 77.0% (FOA1 group vs. FO1 group) and 137.4% (FOA2 group vs. FO2 group), respec⁃tively, and the latter had a significant difference ( P<0.05) . Two⁃factor variance analysis results showed that oxi⁃dized fish oil had a significant influence on serum malondialdehyde ( MDA) content ( P<0.05) , and oxidized fish oil and Arg had a significant interaction on serum T⁃AOC ( P<0.05) . The results indicate that a certain amount of oxidized fish oil addition can reduce the growth and serum antioxidant capacity of yellow catfish, but a certain a⁃mount of Arg addition can alleviate the inhibition induced by oxidized fish oil for growth, and enhance the body’ s antioxidant capacity.关键词
