Poultry systems intended for the production of broilers usually handle high poultry densities to obtain a higher production rate of meat by confinement area, situation that results in animal stress and thus zootechnical low yields. Considering that the use of probiotics in animal nutrition is an alternative to improve production rates and replace the use of growth-promoter antibiotics, this research evaluated the effect of a consortium of microorganisms, probiotics, Bacillus clausii, Saccharomyces cerevisiae and Lactococuslactis on the weight gain and food conversion rate in broilers. Probiotics were administered in drinking water at the rate of 1 x 108 UFC of each microorganism, by 2 ml g-1 of food offered at day 10, 20 and 30 of growth counted from the second day of life of the chicken. Weighing of animals took place at day 10,30, and 42 of production. Statistical analyses showed significant differences with P<0,05 between the two treatments, demonstrating that the probiotic supplemented population gained an average weight of 65,97 g/day, 1,74 food conversion and 0% mortality. These data suggest that probiotics have a positive effect on weight gain and feed conversion in broilers.
