0.05). The highest survival rate was revealed in the diet 75%, which was not affected by the level of AquPro in the diet. The highest activity of lipase, amylase and acid protease enzymes, respectively, from pyloric caeca, intestine and stomach were observed in diet 50%, which showed a significant difference compared to other diets (p< 0.05). The findings of growth performance and lipase, amylase and acid protease activity were revealed the diet containing 50% AquPro could be appropriate for rainbow trout growth]]>

The highest amount of lysozyme and IgM was observed in the diet fed with 5 g/kg olive leaf extract (p<0.05). According to the results, olive leaf extract in Gilan province, Iran, at both levels of 1 and 5 g/kg resulted in reduction of food conversion ratio and improvement of some blood and immune parameters in common carp fingerlings.]]>

Microbial results showed that the treatment 4 was the best and the shelf life of this treatment was 6 days more than treatment 1. [M1] p<0.05 [M1] یعنی اختلاف معنی دار وجود دارد. لطفا اصلاح شود.]]>

0.05), but the number of white blood cells, hemoglobin, hematocrit, eosinophil were significantly different with the control group in different treatments (P<0.05). The results of eosinophil showed that exposure to silver nanoparticles caused a significant effect of dietary supplements and increased the amount of blood eosinophil (P<0.05), so that the bacteria and synbiotics have the same function, but raffinose had a growth-enhancing effect. The study of hematocrit index showed that dietary supplements undergoing exposure to silver nanoparticles had a significant effect on the hematocrit index and its increase (P<0.05), so that the bacteria and raffinose had the same function, but synbiotic was able to produce the increasing effect. The results of hemoglobin showed that exposure with silver nanoparticles had a significant effect on hemoglobin (P<0.05). Food supplements had a positive effect on goldfish immune system and increased hemoglobin in exposure to nanosilver. The raffinose had the same performance, but the bacteria had an increasing effect. According to the results, the dietary supplement of the bacteria had the highest effect on the hemoglobin indices and it has been effective in co-administration with other supplements in the blood monocyte index. Raffinose supplementation had the greatest effect on RBC, and eosinophilic indices. Among the supplements, the synbiotic food with effect on hematocrit, white blood cell, neutrophil, biochemical among food supplements has more effect.]]>
