Effects of Fermented Black Soldier Fly on Growth,Liver Biochemical Indices,Digestion and Absorption and Immunity of Channel Catfish(Ictalurus punctatus)
摘要
Abstract
This study aimed to investigate the effects of adding fermented black soldier fly(BSF)to the diet on the growth,liver biochemical indices,digestion and absorption and immunity of channel catfish(Ictalurus punctatus).Four diets with 0(G0),2%(G2),4%(G4)and 8%(G8)fermented BSF by fresh matter(the corresponding air-dry matter addition was 0,10.4,20.8 and 41.6 g/kg,respectively)were formulated to be isonitrogenous and isolipidic.A total of 480 Ictalurus punctatuss with an initial body weight of(2.75±0.01)g were randomly divided into four groups,with three replicates per group and 40 fish per replicate.A 56-day feeding trial was conducted.The results showed that the feeding rate(FR)of Ictalurus punctatus was not significantly affected by the addition of fermented BSF in the diet(P＞0.05).Compared with the control group(G0 group),the weight gain rate(WGR),specific growth rate(SGR)and condition factor(CF)in the G2 group were significantly improved(P＜0.05);the visceral-somatic index(VSI),hepato-somatic index(HSI)and intestinal-somatic index(ISI)in the G8 group were significantly reduced(P＜0.05);the contents of triglycerides(TG)and total cholesterol(TC),and the activities of glutamic-pyruvic transaminase(GPT)and glutamic-oxaloacetic transaminase(GOT)in the liver of Ictalurus punctatus in the G2 group were signifi-cantly decreased(P＜0.05);the alkaline phosphatase(AKP)and acid phosphatase(ACP)activities in the liver of the G4 group was significantly increased(P＜0.05),while the AKP and ACP activities and comple-ment 3(C3)content in the G2 groups was significantly increased(P＜0.05);the activities of intestinal trypsin and Na+-K+-ATPase in the G2 group were significantly increased(P＜0.05).Moreover,the muscular thick-ness,villus length and goblet cell count of intestine showed a trend of first increasing and then decreasing with the addition of fermented BSF,and these parameters were significantly higher in the G2 group than in the con-trol group(P＜0.05).In summary,the addition of fermented BSF to the diet of Ictalurus punctatus promotes growth,enhances digestion and absorption ability,protects liver health,and improves non-specific immunity.The effect is the best when the fermented BSF addition is 2%on the basis of fresh matter(equivalent to 10.4 g/kg on the basis of air-dry matter).[Chinese Journal of Animal Nutrition,2025,37(3):1940-1953]关键词
