An assessment the effect of Fructo-oligosaccharide on growth performance, survival and hematological factors in sturgeon juvenile (Acipenser sttellatus)
The purpose of this study was to evaluate the effect of Fructo-oligosaccharide (FOS) on growth and survival performances of sturgeon juvenile fish (Acipenser stellatus). 90 sturgeon fry fishes (average weight 30.16±0/14 gram) has been brought from Sturgeon International, Research Institute and stored in fiberglass tanks using randomize design with 3 treatments each with 3 replicates in relative constant physico-chemical water parameters(P>0.05) then fed with basal adaptive food for two weeks. Fry fed 11 weeks with diets containing 0% (Basal food), 1% and 2% oligofructose (Raftilose p95, Sigma Co.) added to the basal food. The results revealed that 1% pribiotic compare to other treatments caused increasing weight gain, specific growth rate, feed conversion, feed efficiency, protein efficiency ratio and liver indices significantly (p<0.05) but there is no any significant difference between treatment's survival rates (p> 0.05). At the end of experiment, after bleeding from sample fries, the hematological characters showed that there are no any differences between hemoglobin, WBC and RBC numbers, hematocrit, MCV, MCH and MCHC between treatments(P>0.05) although the number of WBC in 1% and numbers of neutrophils in 1 and 2% prebiotic had differences with zero% significantly (P<0.05). Based on these results good influence on the improving growth and feeding performances by oligofroctose as prebiotic was proved in Acipenser stellatus fries and 1% level was the best.

| Summary: | The purpose of this study was to evaluate the effect of Fructo-oligosaccharide (FOS) on
growth and survival performances of sturgeon juvenile fish (Acipenser stellatus). 90 sturgeon
fry fishes (average weight 30.16±0/14 gram) has been brought from Sturgeon International,
Research Institute and stored in fiberglass tanks using randomize design with 3 treatments
each with 3 replicates in relative constant physico-chemical water parameters(P>0.05) then
fed with basal adaptive food for two weeks. Fry fed 11 weeks with diets containing 0% (Basal
food), 1% and 2% oligofructose (Raftilose p95, Sigma Co.) added to the basal food. The
results revealed that 1% pribiotic compare to other treatments caused increasing weight gain,
specific growth rate, feed conversion, feed efficiency, protein efficiency ratio and liver indices
significantly (p<0.05) but there is no any significant difference between treatment's survival
rates (p> 0.05). At the end of experiment, after bleeding from sample fries, the hematological
characters showed that there are no any differences between hemoglobin, WBC and RBC
numbers, hematocrit, MCV, MCH and MCHC between treatments(P>0.05) although the
number of WBC in 1% and numbers of neutrophils in 1 and 2% prebiotic had differences
with zero% significantly (P<0.05). Based on these results good influence on the improving
growth and feeding performances by oligofroctose as prebiotic was proved in Acipenser
stellatus fries and 1% level was the best. |
