Probiotics are used as growth promotor and for increasing the resistance of fishes against stress and disaeses. In this research, the effects ofseperate and combined use of bacterium Lactobacillus buchneri and Saccharomyces cerevisiae on the respiratory burst activity and growth factors in rainbow trout. Fish (ABW= 250 ± 50) were fed on diet containing supplemented diet for 30 days in 4 groups with two repetitions. The results of this study showed that the use of supplements did not significantly affect respiratory burst (activity and growth factors (P≥0/05
