The aim of this study was to examine the effectiveness of probiotics, prebiotics and synbiotics in enhancing the immune responses of vannameishrimp (Litopenaeus vannamei) to Vibrio harveyi infection. This research was comprised of five treatments, namely:T0(+)= Positive control, T0(-)= Negative control, T1= 1% probiotic , T2= 2% prebiotic, and T3= synbiotic (1% probiotic+2% prebiotic). The Probiotic SKT-b (dose 106 CFU/ml) and oligosaccharides from sweet potatos as a prebiotic were used in this study. The prebiotics and probiotics were supplemented into the shrimp diet. The study revealed that higher immune responses were observed in T3 with total heamocytes of3.36±0.05 x106 to 9.32±0.05x106 cells/ml, phagocytic activity of 16.48±0.14 to 77.55±0.22%, and phenoloxidase activity of 0.128±0.03 to 0.591±0.01. We concluded that the addition of synbiotics in the feed resulted in better immune responses compared to the addition of probiotics and prebiotics. © 2015, BIOFLUX SRL. All rights reserved.
