Title

EFFECTS OF DIFFERENT DIETARY SELENIUM SOURCES (SELENOMETHIONINE AND SELENITE) ON GROWTH PERFORMANCE, HAEMATOCIRT AND SOME BLOOD PARAMETERS ON RAINBOW TROUT (ONCORHYNCHUS MYKISS)

Pages

  41-50

Abstract

 This study was aimed to determine the role of SELENOMETHIONINE and SELENITE on the GROWTH, HAEMATOCIRT and some blood parameters of RAINBOW TROUT (Oncorhynchus mykiss). A twelve-week feeding trial was undertaken with seven experimental dietary treatments based on a common commercial trout grower diet (FFT2, Chineh, Tehran, Iran) supplemented with various levels of SELENOMETHIONINE or SELENITE.. RAINBOW TROUT (mean weight 22±2.5 g) were acquired, acclimated to a 21 tank recirculation (300 l) at a density of 30 fish per tank. All fish in each tank were weighed at t=0 and were fed three times daily at 8:00, 14:00 and 20:00 with each feed. Daily feeding rate was about fed 3% body weight per day. No significant difference was observed in survival rate, FCR and SGR due to the inclusion of selenium in fish diets (P>0.05). Weight gain of RAINBOW TROUT increased significantly with the increase of selenium level in the tested diets. The higher weight gain (464.0±60.2 g) was obtained when fish fed on 8 mg kg-1 selenomethionin diet, while the lowest one (390.0±36.5 g) was obtained at the control group. There were significant decreases (P<0.05) in WBC of 4 mg kg-1 SELENOMETHIONINE and 8 mg kg-1 SELENITE with the control and also there were significant decreases (P<0.05) in RBCs of 2 mg kg-1 SELENOMETHIONINE with the control. Physiological parameters(haematocirt, hemoglobin, Differential cell count, MCV, MCH and MCHC) were not affected by Se supplementation (P>0.05).
