Abstract

Objective. To evaluate the probiotic activity of the biopreparations PROBIOLACTIL®, SUBTILPROBIO® and their mixture on microbiological, productive and health indicators in broilers. Materials and methods. An experiment with a completely randomized design was carried out for 42 days with four treatments: T1. Only based on diet (control group), T2. PROBIOLACTIL® (bioprepared with Lactobacillus salivarius C-65) + diet, T3. SUBTILPROBIO® (Bioprepared with Bacillus subtilis E-44) + diet and T4. Mixture of both biopreparations + diet. Results. The treatments where the probiotics were applied presented an increase in total lactobacilli and total anaerobes (p≤0.05) and a reduction in total coliforms. In the productive indicators, it was noticed that the live weight was higher in the birds treated with the mixture, as it showed an improvement in weight gain, average daily gain, feed conversion and carcass yield. The application of additives reduced mortality and increased viability in birds. Conclusions. The synergistic activity of Lactobacillus salivarius and Bacillus subtilis increases probiotic activity and favors the productive performance and viability of broilers.
