复方中草药投喂策略对凡纳滨对虾生长、消化及非特异性免疫功能的影响

Effects of feeding strategy of dietary Chinese herbs on growth performance, digestive enzymes and non-specific immunity of Litopennaus vannamei

    摘要
  • 摘要: 设计9组试验组，测定饲料中添加不同浓度的复方中草药以及不同的投喂策略对凡纳滨对虾（Litopenaeus vannamei）生长、消化酶及非特异性免疫功能的影响，饲料组分别为D0、D2、D4（连续投喂对照组、0.2%中草药组、0.4%中草药组）、1D2-1D0、1D4-1D0（1周0.2%、0.4%中草药饲料-1周对照饲料）、1D2-2D0、1D4-2D0（1周0.2%、0.4%中草药饲料-2周对照饲料）、1D2-3D0、1D4-3D0（1周0.2%、0.4%中草药饲料-3周对照饲料）。结果表明，D2组和1D4-2D0组的增重率显著高于D0组；D2组饵料系数显著低于D0组；D4组的成活率显著低于D0组和1D4-1D0组；D0组的肝胰腺蛋白酶活性和血淋巴总蛋白(TP)质量浓度低于其他各组，而血淋巴谷草转氨酶（AST）和谷丙转氨酶（ALT）含量显著高于其他组；超氧化物歧化酶(SOD)和碱性磷酸酶活性(AKP)以1D4-1D0组最高，过氧化物酶(POD)活性则以D0组最高。因此，连续投喂0.2%中草药饲料以及1周0.4%中草药饲料-2周对照饲料的策略可以使凡纳滨对虾获得较好的生长性能和免疫机能。

     

    Abstract: Nine treatments are designed to assess the effects of different concentration and feeding strategy of dietary Chinese herbs on the growth performance, digestive enzymes and non-specific immunity of Pacific white shrimp, Litopenaeus vannamei. The treatments include group D0, D2, D4 (fed with basic diet, 0.2%, 0.4% Chinese herbs continuously); group 1D2-1D0, 1D4-1D0 (fed with 0.2%, 0.4% herb-containing diet for 1 week and then with basic diet for 1 week); group 1D2-2D0, 1D4-2D0 (fed with 0.2%, 0.4% herb-containing diet for 1 week and then with basic diet for 2 weeks); group 1D2-3D0, 1D4-3D0 (fed with 0.2%, 0.4% herb-containing diet for 1 week and then with basic diet for 3 weeks). The results indicate that the weight gain of group D2 and 1D4-2D0 are significantly higher than that of group D0; feed efficiency of shrimps fed with diet D2 is lower than those fed with diet D0; and the survival of group D4 is particularly lower than that of group D0 and 1D4-1D0. The activities of liver catharsis and the concentration of total protein (TP) in haemolymph of group D0 are lowest, while alanine aminotransferase (ALT), aspartate aminotransferase (AST) and peroxidase (POD) are highest. However, the highest activities of superoxide dismutase (SOD) and alkaline phosphatase (AKP) are observed in group 1D4-1D0. In conclusion, the strategies of feeding with 0.2% Chinese herb continuously and with 0.4% herb-containing diet for 1 week following with basic diet for 2 weeks can improve the growth performance and immunity of L.vannamei.
