The main purpose of this study was to investigate the effect of different bacterial type in probiotics on the growth performance of Nile tilapia. In this study, commercial probiotics with a different type of bacteria were added to the diet. The first group, as control, was fed with a commercial diet without probiotic. The second group was fed with commercial diet plus probiotic X contained Lactobacillus sp., Bacillus sp. and Pseudomonas sp. The third group was applied commercial diet plus probiotic Y contained Lactobacillus sp., Bacillus sp. and Bifidobacterium sp. Feeding trial was performed for 30 days. The result showed that the growth performance of Nile Tilapia including weight gain (WG) and specific growth rate (SGR) was significantly higher than the control group (P<0.05). The addition of probiotics in the commercial diet also improved feed utilization significantly. The best growth performance was obtained in the third group where the probiotic Y applied. Different bacterial strain in probiotic could give a different effect on the growth performance of Nile Tilapia because of their different action mode in fish. Therefore, the appropriate selection of probiotic strains can lead to specific advantages for species in aquaculture.
