CHIRIBOGA CHUCHUCA, Carlos et al. Use of vinegar and oreganón Plectranthus amboinicus (Lour.) Spreng infusion for "Acriollados" bred broilers (Gallus gallus domesticus). Acta Agron. [online]. 2016, vol.65, n.3, pp.298-303. ISSN 0120-2812.  https://doi.org/10.15446/acag.v65n3.46222.

This research was conducted at the Farm Santa Inés, belonging to the Technical University of Machala, using 160 bred broilers (Gallus gallus domesticus ), stayed the same as trying to meet the highest standards of management and health, however to cause challenges no vaccines or antibiotic treatment within the farm. The aim was to determine the efficacy of vinegar and infusion of oreganón Plectranthus amboinicus in acriollados bred broilers. The research lasted 42 days, 16 were randomized groups of 10 chickens each, considering 4 treatments (T1 = vinegar, T2 = vinegar + oreganón infusion, T3 = oreganón infusion, T4 = control) with 4 replicates each. Balanced administered free of antibiotics, food consumption data and daily treated water were performed, the weights of the birds weekly; stool samples were collected at the start, middle and end of the assay. In conclusion, the field variables did not obtain statistically significant differences in treatment, but in the Microbiology, the T1, T2 and T3 showed efficiencies decrease when compared to T4, but T3 at the end of the research differed from the T1, T2, and T4. Assuming oreganón Plectranthus amboinicus infusion induces a reduction in the number of CFU in both Total Flora and coliforms.
