This study were investigated the Effects of Glucan-Mannan oligosaccharide on growth, hematological indices and body composition of Beluga Juvenile for 42 days. Basal diet were supplemented with 0(control), 1.5, 3 and 4.5 g pre-biotic Glucan-Mannan oligosaccharide per kg diet in a total randomized design trial in 4 groups with triplicate per treatments. The experiment carried out in 12 fiberglass tanks. 180 juveniles Beluga with initially average weight 48±0.12 gr were stocked with density of 15 per tanks and fed a day. The results have show there were no significant differences in body composition and the protein and lipid contents among the groups (P>0.05). These fish fed diet with 1.5 g pre-biotic Glucan-Mannan oligosaccharide per kg diet had significant different than control diets and lowest of FCR was recorded in 1.5 g/kg MOS and didn't show significant differences with control groups. And shown significant differences in white and red blood cells, hematocrit and hemoglobin and mean corpuscular hemoglobin in diet with 1.5 g pre-biotic with control diets<0.05). There aren’t significant differences in neutrophill and eosinophill count in whole groups with control groups (P>0.05). Result indicated that 1.5g.kg Glucan-Mannan oligosaccharide can improved growth performance, and immunity systems and it is appropriate for supplementation in the diet of Beluga juveniles.
