Probiotic effects on growth performance and microbiome of Nile tilapia (Oreochromis niloticus) in a biofloc system

Two research trials were conducted to evaluate Nile tilapia (Oreochromis niloticus) growth performance when fed top-coated probiotics. Trial A incorporated juvenile tilapia (71 g), treatment diets were top-coated with two probiotics, Bacillus velenzensis AP193 and BiOWiSH Feedbuilder Syn3 . In Trial B, juvenile tilapia (5g) were fed treatment diets top-coated with two different concentrations of BiOWiSH Feedbuilder Syn3. Tilapia were offered commercial feed (38 % protein floating tilapia feed) as a control diet for both trials.
