چکیده
In the present study selenium nanoparticles (Se-NPs) and zinc nanoparticles (Zn-NPs) included in the diets of white shrimp at 0 mg (control), 0.3 mg Se-NPs/ kg feed (T1), 0.15 mg Se-NPs+15 mg Zn-NPs/kg feed (T2) and 30 mg Zn-NPs/kg feed (T3). After 8 weeks, shrimps fed both Se-NPs and Zn-NPs showed higher (p<0.05) final body weigh, weigh gain, and SGR than shrimp fed the control diet. On the other hand, the FCR was decreased by Se-NPs and Zn-NPs when compared to the control whereas both Se-NPs+Zn-NPs revealed lower FCR than the other groups (p<0.05). Shrimp fed Se-NPs or Se-NPs +Zn-NPs revealed higher survival rate than shrimp fed the control and Zn-NPs while shrimp fed Zn-NPs showed higher survival rate than shrimp fed the control (p<0.05). The total haemocyte count, large granular cells, semi granular cells, and semi granular cells revealed higher counts in shrimps fed Se-NPs and Zn-NPs than the control (p<0.05). Shrimp fed Se-NPs or Se-NPs+ Zn-NPs revealed higher catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidas (GPX) activities than shrimp fed the control and Zn-NPs while shrimp fed Zn-NPs showed higher catalase activity than shrimp fed the control (P<0.05). The total protein, lysozyme, and phenoloxidase activities increased in shrimp fed Se-NPs or/and Zn-NPs with the highest being in shrimp fed both in shrimp fed Se-NPs and Zn-NPs followed by those fed Se-NPs then Zn-NPs when compare to the control (p<0.05). In conclusion, the co supplementation of Se-NPs and Zn-NPs showed higher performances, antioxidant status, and immune responses in white shrimp than the individual supplementation of Se-NPs or Zn-NPs.
