Effects of Fish Meal Replacement by Black Soldier Fly (Hermetia illucens L.) Larvae Meal on Growth Performance, Body Composition,Plasma Biochemical Indexes and Tissue Structure of Juvenile Lateolabrax japonicas
摘要
Abstract
In order to study the effects of fish meal replacement by black soldier fly (Hermetia illucens L.) larvae meal on growth performance,body composition,plasma biochemical indexes and tissue structure of juvenile Lateolabrax japonicas,six isonitrogenous (crude protein content was 39.85％) and isoenergetic (gross energy was 17.9 MJ/kg) experimental diets were prepared by replacing 0 (G0,as control),10％ (G10),20％ (G20),30％ (G30),40％ (G40) and 50％ (G50) of fish meal with black soldier fly larvae meal based on a basal diet (fish meal content was 28.00％ and crude protein content in fish meal was 67.50％).A total of 540 juvenile Lateolabrax japonicas with an initial body weight of 5.2 g were randomly divided into 6 groups with 3 replicates per group and 30 fish per replicate.The experiment lasted for 56 days.The results showed that the final body weight,weight gain rate,specific growth rate,feed intake,protein efficiency ratio,feed coefficient and survival rate were not significantly affected by different replacement ratios of fish meal by black soldier fly larvae meal (P＞0.05).No significant difference was found in condition factor among all groups (P＞0.05),but the viscerosomtic index and hepatosomatic index in G50 group were significantly higher than those in G0 group (P＜0.05).The contents of crude protein,ash,moisture,calcium,total phosphorus and essential amino acids in whole body were not significantly different among all groups (P＞0.05),but the crude lipid content in G20 to G50 groups was significantly higher than that in G0 group (P＜0.05).The plasma globulin content in G20 group was significantly higher than that in G0 group (P＜0.05),but the other plasma biochemical indexes in replacing groups (G10 to G50 groups) had no significant differences compared with G0 group (P＞0.05).The number of hepatocytes with empty vacuoles degeneration and nuclear disappear increased progressively with the replacement ratio increasing.Intestinal villus height in G0 group was the highest,which was significantly higher than that in G10 and G40 groups (P＜0.05);except G20 group,the muscular thickness in other replacing groups was significantly decreased compared with G0 group (P＜0.05).Base on the results,it is concluded that 50％ of fish meal could be replaced by black soldier fly larvae meal (27.8％ black soldier fly larvae meal in basal diet and account for 23.7％ of diet protein) without causing a significant reduction in growth performance,but high replacement ratios cause fat deposition increase,hepatic pathological changes and intestinal development damage.关键词
