Resumo: | A six week study was conducted to investigate the supplementation of prebiotic (Mannan oligosaccharide – MOS, from yeast Saccharomyces cerevisiae), probiotic (Bacillus subtilis – BS, C-3102 strain) and their combination in diets for Nile tilapia. 192 fishes (4.03 ± 0.28 g) were distributed into 16 tanks (40-L), in a completely randomized design (n=4). The following treatments were evaluated: control; prebiotic - 2 g MOS kg-1; probiotic - 2 g BS kg-1 and synbiotic - 1 g MOS kg-1 plus 1 g BS kg-1. Fishes fed diets pre-, pro- and synbiotic supplemented performed better in average daily gain, feed conversion rate, specific growth rate, protein efficiency ratio, carcass yield, total and standard length and body height than those maintained on control diets. The probiotic supplementation resulted in higher villus height and intestinal perimeter ratio than the control diet while the pre- and synbiotic supplementation in diets resulted in higher intestinal perimeter ratio. Carcass protein and ether extract were, respectively, higher and lower in fish fed synbiotic diets than other fish. The results of this study indicated that the mannan oligosaccharide and Bacillus subtilis supplementation, isolated or combined (synbiotic), could improve growth, body index, intestine morphometry and carcass composition in Nile tilapia.
