| 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.... |
