Abstract: (289 Views) |
| This study was conducted with the purpose of investigating the addition of different concentrations of selenium and iron nanoparticles to the diet and its effect on the values of growth indicators and the percentage of carcass chemical compounds in rainbow trout (Onchorhynchus mykiss). In this research, 240 rainbow trout with an average weight of 5.21 ± 0.02 grams were fed for 8 weeks with diets containing 0.5, 1, 2 mg/kg of selenium nanoparticles in amounts of 10, 30 and 50 mg. iron nanoparticles in a completely randomized design to 4 experimental treatments; Treatment 1 (control group), treatment 2 (0.5 Se + 10 Fe), treatment 3 (1 Se + 30 Fe) and treatment 4 (2 Se + 50 Fe) were each divided by 3 repetitions and fed as free ions. According to the results, the values of body weight, percentage of weight gain, specific growth rate and protein efficiency ratio in the amount of 2 mg of selenium nanoparticles and 50 mg of iron nanoparticles increased compared to other values and had a significant difference with other treatments (p<0.05). Also, food conversion coefficient, in amounts of 2 mg of selenium nanoparticles and 50 mg of iron nanoparticles, had a significant difference with other treatments (p<0.05). In carcass analysis, the highest amount of protein was found in the treatment of 0.5 mg/kg of selenium nanoparticles and 10 mg of iron nanoparticles, which was significantly different from the control treatment (p<0.05). And by increasing the amount of selenium and iron nanoparticles in the experimental treatments, the amount of protein increased. Also, in terms of the amount of fat, a significant difference was observed between the experimental treatments and the control treatment (p<0.05). The results showed that the use of 2 and 0.5 mg of selenium nanoparticles and 10 and 50 mg of iron nanoparticles has a good effect on rainbow trout. |
