Actividad probiótica de PROBIOLACTIL®, SUBTILPROBIO® y su mezcla en pollos de ceba

Abstract

Biopreparations with Lactobacillus salivarius and Bacillus subtilis are used as probiotics in poultry farming due to their beneficial effects on the intestinal ecosystem. 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. Control 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 anaerobes (p≤0.05) and a reduction in total coliforms. Live weight was higher in birds treated with the mixture, and weight gain, average daily gain, feed conversion and carcass yield were improved. 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.
