Abstract

The objective of this study was to evaluate alterations in the intestinal tract microbiota and growth performance of Nile tilapia (Orechromis niloticus) fed diets supplemented with Lactobacillus plantarum. One hundred and twenty sexually reversed fingerlings were stocked in six aquaria and divided into two treatments, in triplicate: fingerlings fed diet supplement with L. plantarum and fingerlings fed control diet. After 42 days, tilapia fed the diet supplemented with L. plantarum had higher amount of lactic acid bacteria, 3,5x104 CFU and 1,1x102 CFU per g tract, and lower total bacteria, 5,8x106 CFU and 5,2x107 CFU per g tract, than the fish fed the control diet. Furthermore, probiotics increased 3,9% the weekly weight gain, 15,6% final biomass and 15,5% feed efficiency. The use of probiotics in tilapia hatcheries boosts productivity.
