Effects of Fish Meal Replacement by Black Soldier Fly ( Hermetia illucens) Larvae Meal on Growth Performance, Serum Biochemical Indices and Meat Quality of Juvenile Yellow Catfish ( Pelteobagrus fulvidraco)
摘要
Abstract
The aim of this experiment was to evaluate the effects of replacing fish meal with black soldier fly (Hermetia illucens) larvae meal on growth performance, body composition, amino acid composition in muscle and serum biochemical indices of juvenile yellow catfish (Pelteobagrus fulvidraco). Six isonitrogenous (crude protein content was 44.55%) and isolipidic (crude lipid content was 7.94%) experimental diets were formulated by repla?cing 0 (G0 group, as a control group), 10%(G10 group), 20%(G20 group), 30%(G30 group), 40%(G40 group) and 50%(G50 group) of fish meal with black soldier fly larvae meal (made by eight instar larva black sol?dier fly larvae that fed with peanut bran) based on a basal diet (fish meal content was 30%).A total of 720 juven?ile yellow catfish with an initial body weight of 2.00 g were randomly divided into 6 groups with 4 replicates per group and 30 fish per replicate.The experiment lasted for 8 weeks.The results showed that the survival rate was not significantly affected by different replacement ratios of fish meal by black soldier fly larvae meal (P＞0.05). Com?pared with the G0 group, the final body weight and specific growth rate were significantly decreased (P＜0.05) and the lipid deposition rate was significantly increased ( P＜0.05) in G40 and G50 groups, but no significant differ?ences were found in G10, G20 and G30 groups (P＞0.05).There were no significant differences in protein deposi?tion rate, protein efficiency ratio and feed conversion ratio among all groups (P＞0.05). The contents of moisture, crude protein, crude lipid and ash in whole body and moisture, crude lipid and ash in muscle were not significantly different among all groups (P＞0.05), but the muscle crude protein content in G50 group was significantly higher than that in G0 group (P＜0.05). The muscle arginine and valine contents in G30 group were significantly higher than those in G0 group (P＜0.05). There were no significant differences in the contents of four flavor amino acids (glutamate, glycine, alanine and aspartate) in muscle among all groups (P＞0.05).Compared with G0 group, the serum glutamic?pyruvic transaminase (GPT) activity in G30 was significantly decreased (P＜0.05).And the serum glutamic?oxalacetic transminease (GOT) activity, uric acid ( UA) and triglyceride ( TG) contents in G30 group were lower than those in G0 group, but the differences were not significant ( P＞0.05). In conclusion, this study shows that 30% of fish meal can be replaced by black soldier fly larvae meal (made with eight instar larva black soldier fly larvae that fed with peanut bran) base on the basal diet with 30% fish meal (44.55% crude protein and 7.94% crude lipid in dry matter basis condition), and thus account of 12.78% of diet protein, which can decrease the GPT and GOT activities, UA and TG contents in serum, but without significant effects on growth performance and flavor amino acid composition in muscle of juvenile yellow catfish.[ Chinese Journal of Animal Nutrition, 2019, 31(6):2788?2799]关键词
