Effect of Ocimum basilicum in Cobb 500 chickens on the productive and bacterial parameters

The research was developed at the Santa Inés Farm, of the Faculty of Agricultural Sciences of the Universidad Técnica de Machala, the objective was to evaluate the effect of the infusion of Ocimum basilicum in Cobb 500 chickens on the productive parameters and bacterial control. For the experiment, a Completely Random Design was applied to evaluate five treatments each with four experimental units of 10 chickens (200 birds). The treatments were: T1, T2, T3, and T4, to which 2 ml of infusion of O. basilicum was added at 10%, 20%, 30% and 40% respectively for each liter of drinking water and T5 normal water. For the welfare of the birds, management was used for open buildings, administering a balanced feed free of Antibiotic Growth Promoters. The variables evaluated were: live weight of the bird, consumption of feed and accumulated water, feed conversion, mortality, total bacterial microbiota and colimetry. For data analysis, the statistical program Statgraphics Centurión XV.I.® was used, subjecting the variables to an ANOVA, prior assumptions of normality and homogeneity, and the Kruskal-Wallis test for those that did not present a normal distribution. To establish the difference between the means, the Bonferroni multiple comparison procedure was used with a 95.0% confidence level. The results conclude that there is no effect on the parameters evaluated, it does not present a health risk and that due to its biopharmaceutical properties it could be used as an alternative to synthetic antibiotics.
