Effects of Fish Meal Replacement by Maggot Meal on Growth Performance,Body Composition and Plasma Biochemical Indexes of Juvenile Yellow Catfish (Peltobagrus fulvidraco)
摘要
Abstract
This experiment was conducted to investigate the effects of fish meal replacement by maggot meal on growth performance, body composition and plasma biochemical indexes of juvenile yellow catfish (Pelto-bagrus fulvidraco). Six isonitrogenous (39. 5% ) and isoenergetic (16. 8 MJ/kg) experimental diets were formulated with 0, 20% , 40% , 60% , 80% and 100% fish meal replacement by maggot meal on basal diet basis. A total of 960 juvenile yellow catfish with an average body weight of 2.02 g were randomly assigned to 6 groups with 4 replicates per group and 40 fish per replicate. The fish in the 6 groups were fed the 6 experimental diets, which were named groups GO, G20, G40, G60, G80 and G100, respectively. The experiment lasted for 60 days. The results showed as follows: there was no significant difference in survival rate among all groups (P>0.05). Compared with the control group (group GO) , the final body weight, weight gain rate, specific growth rate, protein efficiency ratio and protein deposition rate in groups G40 to G100 were significantly decreased (P<0.05), while the feed coefficient was significantly increased (P<0.05). The feed intake in group G80 was significantly higher than that in control group (P <0. 05). No significant differences were found among all groups in condition factor, viscerosomtic index, hepatosomatic index and contents of moisture, crude protein, crude lipid, ash, calcium and total phosphorus in whole body (P >0. 05). There were no significant differences in urea nitrogen content, glutamic-pyruvic transaminase and glutamic-oxalacetic transaminase activities in plasma with increasing maggot meal in diets (P >0.05). Compared with the control group, plasma glucose content in groups G60 to G80, and plasma high density lipoprotein cholesterol content in groups G40 to G100 were significantly increased (P <0. 05) , while plasma total protein content in groups G80 to G100, plasma cholesterol content in groups G20 to G100, plasma triglyceride content in groups G20 to G80 and plasma low density lipoprotein cholesterol content in group G60 were significantly decreased (P < 0. 05). The results indicate that a significant effect is found in growth performance and some plasma biochemical indexes of juvenile yellow catfish when the fish meal replacement by maggot meal is over 20%. With growth performance as an evaluating index, it is suggested that fish meal replacement by maggot meal should not be more than 20% in diets of juvenile yellow catfish.关键词
