    摘要:

    , 300 mg/kg βG、记为养殖结束后(WSSV)G2G1G1G1G1组血细胞总数和酚氧化酶活性差异不显著(<0.05)<0.05); G1G4分别显著低于组G1WSSV, , G1−G4组显著降低。结果表明联合添加能一定程度提高凡纳滨对虾生长性能与单独添加三者联合添加均能显著提高凡纳滨对虾的非特异性免疫、抗氧化能力和抗病力。

    Abstract:

    A feeding trial was conducted to investigate G) with selenium (Se) and vitamin E (VE) on the growth performance, serum immune, and antioxidant indexes, and disease resistance of with an initial body weight of (0.83±0.02) g were randomly divided into 5 groups and fed one of five diets with added G, 300 mg/kg G+0.2 mg/kg Se+100 mg/kg VE, named G0, G1, G2, G3, and G4, respectively. After 35 d feeding, the shrimps were infected with white spot syndrome virus(WSSV).(WGR) was highest in G2, which was significantly higher than that of G1 by 6.4% (<0.05). Survival rate(SR) in G3 was significantly lower than in G0 and G1 (<0.05). Total hemocyte count (THC) activity increased significantly in G4 (<0.05) compared with G0.<0.05). Acidic phosphatase(ACP) activity in G3 was significantly lower than that in G4(<0.05). Alkaline phosphatase (AKP) activity in G2 was significantly higher than that in the other three treatment groups (<0.05). Glutathione peroxidase (GSH-PX) activity in G4 increased significantly compared with the other four groups (<0.05). There was no significant difference among the five groups in glutathione transferase (GST) activity (>0.05). Catalase (CAT) activity was highest in G1, being significantly higher than that in G2 and G4 (<0.05). The highest value of superoxide dismutase (SOD) activity was observed in G2, followed by G1 and G3. The former was significantly different compared with the other four groups (<0.05), and the latter two were increased significantly in comparison to G0 and G4 (<0.05). Malondialdehyde (MDA) content in G1, G2 and G4 decreased significantly compared with G0 and G3 (<0.05). ) radical activity in G1, G2, and G4 was significantly higher than that in G3 (<0.05). Compared with G1, total antioxidant (T-AOC) capacity in G3 increased significantly (<0.05). After 72 h of WSSV infection, the highest cumulative mortality rate (AMR) was observed in G0, AMR in G1–G4 were lower, with a significant decrease in G2 and G4 (<0.05).The relative percent survival (RPS) in these two groups was 30.8% and 26.9%, respectively. In conclusion, the combined addition of G+Se+VE might improve non-specific immunity, antioxidant capacity, and resistance to the white spot syndrome virus (WSSV) in .
