摘　　要：该试验通过研究饲料中添加4%黑水虻酵素,测定杂交鳢(Chnna maculate♀×Chnna argus♂)的生长性能、体成分、血清生化和肝脏抗氧化指标,探讨其应用效果。试验选用180尾初始均重为(5.31±0.01)g的杂交鳢,随机分2组,每组3个重复,每个重复挑选体表健康、活力好的杂交鳢30尾。养殖试验63 d。(1)与对照组相比,试验组杂交鳢的增重率、特定增长率、成活率和形体指标肥满度、肝体比、脏体比、脂体比无显著变化(P>0.05),饲料系数呈现下降趋势(P=0.074)。(2)试验组杂交鳢的血清生化指标谷丙转氨酶、谷草转氨酶、总蛋白、白蛋白、球蛋白、白球比、甘油三酯、胆固醇、葡萄糖、高密度脂蛋白胆固醇和低密度脂蛋白胆固醇无显著变化(P>0.05)。(3)试验组的杂交鳢肝脏谷丙转氨酶活力显著下降、过氧化氢酶活性显著上升(P<0.05),谷草转氨酶、超氧化物歧化酶、丙二醛、谷胱甘肽过氧化物和总抗氧化能力无显著变化(P>0.05)。饲料中添加4%黑水虻酵素可以改善杂交鳢的饲料系数、提高其肝脏抗氧化能力,不会对机体蛋白质、脂肪和糖类代谢产生负面影响。This experiment investigated the growth performance,body composition,serum biochemistry,and Hepatic antioxidant ability of hybrid snakehead(Chnna maculate♀×Chnna argus♂)by adding 4%black soldier fly enzyme.180 hybrid snakeheads with an initial average mass of(5.31±0.01)g were selected for the experiment and randomly divided into 2 groups with 3 replicates in each group.30 hybrid snakeheads with healthy were selected for each replicates.The experiment lasted for 63 days.(1)Compared with the control group,there were no significant difference in the weight gain rate,specific growth rate,and survival rate and the morphological indicators such as the condition factor and hepatosomatic ratio of the experimental group‘s hybrid snakehead(P>0.05).The feed conversion ratio shows a decreasing trend(P=0.074).(2)There was no significant difference in the serum biochemical indicators of the experimental group’s hybrid snakehead,such as alanine aminotransferase,aspartate aminotransferase,total protein,albumin,globulin,triglycerides,cholesterol,glucose,high-density lipoprotein cholesterol,and lowdensity lipoprotein cholesterol(P>0.05).(3)Compared with the control group,the liver catalase activity of experimental group was significantly increased and alanine aminotransferase activity was significantly decreased(P<0.05),while there were no significant difference in superoxide dismutase,malondialdehyde,glutathione peroxidase,total antioxidant capacity,and aspartate aminotransferase(P>0.05).Adding 4%black soldier fly enzyme in the feed can improve the feed conversion ratio of hybrid snakehead,enhance their liver antioxidant capacity,and will not have a negative impact on the protein,lipid and carbohydrate metabolism.
