Abstract
In this study, the effect of fructooligosaccharide as a prebiotic on the growth and density of lactobacillus in intestine of stellate (Acipenser stellatus) has been investigated. To do this, 90 individuals of stellate fingerlings (ten in each replications) were prepared with an average weight of 30.16 ± 0.14 gr from International Sturgeon Research Institute. This study was carried out in a completely randomized design with three replications in fiberglass tanks with 2000 liters volume. They were fed with feed containing 0, 1 and 2 percents of fructooligosaccharide (Raftilos P95, Sigma Company). Results indicated that feed with one percent fructooligosaccharide had a significant effect (P < 0.05) on weight gain, SGR, FCR, FE, PER and HI. The number of colonies regarding to lactobacillus showed a significant increase compared to the control (in one percent fructooligosaccharide). Results indicated that fructooligosaccharide as a prebiotic (in level of one percent in feed) caused good growth capabilities and feed efficiency through increasing the density of lactobacillus in intestine.
