Análisis de la aplicación del bacillus subtilis como probiótico en la producción de pollos de engorde

The present work aims to analyze the use of probiotics, especially bacillus subtilis, as a better alternative to antibiotics in the diet of broilers, considered one of the main protein sources in Ecuador. Research studies related to the subject were used such as "Effect of the use of Bacillus subtilis probiotics in different concentrations, on slaughter weight in broilers" and "Effect of bacillus subtilis on blood metabolites and productive parameters in broilers", among others , each one with different concentrations of probiotics and groups of animals as evidence, where it was shown that the use of bacillus subtilis does have significant effects on the development of the animal, emphasizing that it depends on factors such as: the concentration of probiotics, animal health , type of strains, composition of probiotic, etc. Also addressing issues related to other types and mechanisms of action of probiotics. In a study carried out by Velez in 2019 called "Effect of the use of probiotics Bacillus subtilis in different concentrations, on the slaughter weight in broilers", where it was obtained that the animals administered with B. subtilis at a higher concentration (t3) had a weight of 2.71kg compared to the control (t0) who did not have any concentration of probiotic that presented 2.26kg, resulting in that the treatment with the highest concentration of B. subtilis had a greater weight than the one that did not have the same.
