Abstract
A 30-day experiment was carried out to comparison the effect of carrot and beetroot as natural pigments and synthetic astaxanthin on growth performance, hematological parameters, and tissue color in rainbow trout fingerlings. 150 juvenile rainbow trout with initial mean weight of 21.44 ± 1.25g fed diets containing 50 and 100 mg/kg carrot; 100 mg/kg beetroot; 100 mg/kg synthetic astaxanthin and a control diet. Body weight increasing and specific growth rate were higher in fish fed the diet containing 100 mg beetroot than those of the control diet. Hematological study including red blood cell, white blood cell, hematocrit and hemoglobin showed significant differences between treatments (p<0.05). Carrot and beetroot had higher values of red blood cell, white blood cell, hematocrit and hemoglobin than those of the synthetic astaxanthin and control diet. Triglyceride and cholesterol value were significantly higher in diet containing 100 mg beet (p<0.05). Carotenoid content analysis from skin, tissue and blood revealed that inclusion of plant source of carotenoid including carrot and beetroot resulted in a significant increase in carotenoid concentration (p<0.05). The study concluded that plant source of carotenoid such as carrot and beetroot could improve immune systems in rainbow trout by increasing white and red blood cells and also, fish fed diet supplemented with natural carotenoid (carrot and beet) showed better coloration.

Abstract
This trial was to investigate the effect of emulsifier on growth performance, blood factors and carcass composition in rainbow trout (Onchorhyncus mykiss) fed fat powder diet. A basal diet was formulated using common feed ingredients supplemented with 0.5 and 1% of cholic acid and 2 and 4% of tween80, plus a control diet without emulsifier, leading to five experimental diets. Juvenile rainbow trout with an initial weight of 27.32±2.03 g was fed with experimental diets for 8 weeks. The results showed no significant differences between the value of body weight increasing (BWI), specific growth rate (SGR), feed efficiency ratio (FCR) and hepato somatic index (HSI) (P>0.05) while, visceral somatic index (VSI) was significantly higher in control diet. Emulsifier had significant effects on blood parameters such as white blood cells (WBC), red blood cells (RBC), hematocrit (Hct), hemoglobin (Hb), MCV, MCH and MCHc (P<0.05). Diet containing 0.5% cholic acid showed higher value of WBC while control diet led to higher value of RBC. Results of serum analysis showed that inclusion of emulsifier was effected albumin, glucose and total protein value (P<0.05). 0.5% cholic acid led to the highest value among groups. Assessment of carcass composition showed significant differences among diets (P<0.05). The highest body protein values were observed in diet 0.5% cholic acid while body fat was the lowest in the same diet. It seems that emulsifier could maintain protein by fat utilization and considering no significant differences between different treatments of growth performance addition of 0.5% cholic acid is suggested.

Abstract
In the present study we investigated the effects of lysophospholipid (LPL) different levels on growth, hematological indices, hepatic enzymes and lysozyme activity in rainbow trout fed diets containing fat powder. Experimental diets were four different levels including 0, 3, 6 and 9 gkg-1 LPL and control diet (containing fish oil) each in triplicate. After 56 days of trial, measuring growth parameter suggested improvement of body weight increasing, specific growth rate and feed conversion ratio in LPL 9 compare to other diets containing fat powder, however, control diet owned the highest value (P<0.05). Also, inclusion of LPL caused an increasing in conditional factor of fish fed fat powder diets (P<0.05). According to the hematological indices, white blood cell highest value was observed in diets containing fat powder (P<0.05), while, red blood cell increased significantly by addition of 6 and 9 gkg-1 LPL to fat powder (P<0.05). Furthermore, administration of control and LPL 9 resulted in hematocrit enhancement among experimental diets (P<0.05). Enzyme evaluation revealed lower lysozyme activity in fat powder diets supplemented with 0 and 3 gkg-1 LPL compared other diets (P<0.05). Contrarily, hepatic enzymes elevated in fish fed fat powder diets (P<0.05). However, administration of 9 gkg-1 LPL led to decrease this value (P<0.05). Considering the results of the present study supplementation of 9 g LPL is suggested in rainbow trout diet containing ≈70% fat powder.
