Abstract

In order to effect of prebiotic Immunoster was performed the experiment in period of 8 weeks in 0, 2, 4 percent levels on growth, survival, blood cells count and body compositions of mahi sefid fingerlings with initial weight of 0.35±0.02gr. The experiment was performed with use of compeletly accidental design in one control group and two treatments groups each with 3 replicates and with 150 kutum fingerlings in each tank. Feeding was varied 15-20% of biomass. At the end of experiment, however there was no significant difference in 2 and 4 percent level of Immunoster in camparing with control group (P > 0.05), but mahi sefid fingerlings fed by Immunoster containing diet showed slightly better growth function. Survival rate didn’t have significant difference between treatments. The amount of red blood cells (R.B.Cs) and the amount of white blood cells (W.B.Cs) in one cubic millimeter of blood showed significant difference between control and fingerlings fed with 2 and 4 percents levels of Immunoster (P ≤ 0.01). As 2 percent level of Immunoster had highest of R.B.Cs and W.B.Cs in compare with control group. Also there were significant difference between control and experimental groups the view of protein, fiber and carbohydrate of carcass (P ≤ 0.05).
