Abstract

This study was carried out to compare the effects of different sources of selenium on growth, survival, and some immunological and hematological parameters of whole female Triploid of Rainbow trout (Onchorhynchus mykiss). 10 diets including selenium (selenium sodium), selenium (selenomethionine) and nano-selenium with zero (control), 0. 1 (treatment 1), 0. 5 (treatment 2) and 1 (treatment 3) mg / kg The diet was made. After 8 weeks of nutrition, The final weight was 0. 5 mg / kg Nanoselenium had the highest amount. The highest specific growth factor (4. 26 ± 0. 24) percentage/day was observed in fish fed 0. 5 mg / kg Nanoselenium. The lowest feed conversion ratio (0. 71 ± 023) and the highest weight gain (41. 99 ± 1. 36) g were observed in this treatment, which was significantly different with the control group (P <0. 05). Feeding treatments with nano-selenium also produced the best feed conversion ratio (P <0. 05). Nanoselenium and selenium treatments had significant differences in red and white blood cells, hemoglobin and lysozyme with control (P <0. 05); However, this difference was not observed in treatments fed with selenium (p <0. 05). There was no significant difference in hematocrit in all treatments with the control group (p <0. 05). Immunoglobulin level was significantly different in all treatments on all three sources of nutrition with the control (P <0. 05) and the highest concentration was observed in the one concentration of Nanoselenium. The results showed that the addition of Nanoseleniums up to 0. 5 mg / kg of food resulted in a good proportion of Growth indices, survival, and some blood and immune factors in the fry of the whole female mono-sex Triploid Rainbow trout.
