With low oligosaccharide (LO-SBM) and fermented soybean (FerSBM) meals serving as the primary protein source, this study sought to assess the effects of varying replacement percentages of solvent-extracted soybean meal on the growth and feed utilization efficiency of Pacific white shrimp. For eight weeks, a green water recirculation system was used with the stocking density of 30 shrimp tank-1 (~38 shrimp m-2) The initial weight of the shrimp was 0.29 ± 0.01 g (Mean ± Standard Deviation). Nine different experimental diets were examined. Solvent extracted soybean meal was the primary source of protein of the basal diet, which was replaced with four levels of replacement (40 %, 60 %, 80 %, and 100 %) of each of LO-SBM and FerSBM. All growth metrics in the trial showed no significant differences among diets (p>0.05). Except for phosphorus retention (p<0.001), we observed no significant contrast concerning feeding utilization efficiency (p>0.05). The results revealed that, in the context of natural productivity, the tested soybean ingredients at various levels had no detrimental effects on the growth response or feed utilization of Pacific white shrimp. Furthermore, given the trial’s conditions, a high replacement rate did not correspond to improved performance. The outcome showed the potential of replacing the solvent extracted soybean meal with new variety low oligosaccharide and fermented soybean meals when needed. This research expands upon earlier studies wherein shrimp given LO-SBM and FerSBM shown superior performance compared to those fed diet containing soy protein concentrate, expeller-pressed soybean meal, and animal-based ingredient. Overall, both low oligosaccharide or fermented soybean meal supported good growth of the shrimp and are suitable protein sources.
