摘要: 【目的】评价不同植物单宁制剂对南美白对虾(Litopenaeus vannamei)的饲用效果。【方法】选择初始体重为(6.86±0.02) g的南美白对虾600尾,随机分为5组,每组3个重复,每个重复40尾。制备5组等氮等脂饲料,即基础饲料(G1)、含0.1%和0.2%五倍子单宁制剂饲料(G2、G3)、含0.1%和0.2%栗木单宁制剂饲料(G4、G5)。试验周期为42 d。试验结束后统计对虾重量、数量、摄食量,计算生长性能;围心腔采血并分离血清,测定血清生化及血清抗氧化与免疫指标;分离对虾肠道,匀浆后测定消化酶活性。【结果】与G1组相比,G5组对虾饲料系数显著提高(P<0.05),肠体比、出肉率显著下降(P<0.05);G3组对虾血清甘油三酯及丙二醛含量均显著下降(P<0.05);G5组对虾血清葡萄糖、甘油三酯、尿素氮含量显著下降(P<0.05),而免疫球蛋白M含量显著提高(P<0.05);G2、G3组对虾肠道胰蛋白酶活性显著提高(P<0.05)。【结论】以生长性能、抗氧化能力和肠道消化酶活性为综合评价指标,0.2%五倍子单宁制剂对南美白对虾的应用效果较好。

Abstract: 【Objective】 This study was conducted to evaluate the feeding effect of different plant tannin preparations on Litopenaeus vannamei.【Method】 A total of 600 shrimp were randomly selected and divided into 5 groups with 3 replicates per group and 40 shrimp per replicates.Five isonitrogen and isolipid diets were prepared containing 0 (G1), 0.1% (G2) and 0.2% (G3) Chinese gallotannin preparations, and 0.1% (G4) and 0.2% (G5) chestnut tannin preparations.The experiment was lasted for 42 days.At the end of the experiment, the weight, quantity, and feed intake of shrimp each tank were counted to calculate their growth performance.Blood was collected from the cardiocoelom of the sampled shrimp to separate serum for determination of serum biochemical and serum antioxidant and immune indicators, and the intestine of the shrimp was separated for determination of intestinal digestive enzyme activity.【Result】 Compared with G1, the feed coefficient of shrimp in G5 was significantly increased (P<0.05), while the intestinesomatic index and meat rate were significantly decreased (P<0.05).The content of serum triglyceride of shrimp in G3 was significantly decreased (P<0.05), and the contents of serum glucose, triglyceride and urea nitrogen of shrimp in G5 were significantly decreased (P<0.05).Compared with G1, the content of serum malondialdehyde in G3 was significantly decreased (P<0.05), while the content of serum immunoglobulin M in G5 was significantly increased (P<0.05).Compared with G1, intestinal trypsin activity of shrimp in G2 and G3 were significantly increased (P<0.05).【Conclusion】 Taking growth performance, antioxidant capacity and intestinal digestive enzyme activity as comprehensive evaluation indicators, 0.2% Chinese gallotannin preparation had a good application effect on Litopenaeus vannamei.
