Efecto del vinagre de manzana sobre los índices productivos y pH intestinal en pollos de engorde en el cantón Cevallos

Abstract

In the present investigation entitled "Effect of apple cider vinegar on the productive indices and intestinal pH in broilers of the Cevallos canton ", three doses of commercial apple cider vinegar (Snob brand) were evaluated (1, 3, 5 ml / L) against a control from the first to the seventh week with a frequency of twice a week; The experimental design that was used was a completely randomized design (DCA) comprised of four treatments and six repetitions, the sample units were made up of 12 with a total of 288 chickens, the statistical analysis was carried out using the Tukey test at 95% of probability. The research consisted of two parts, the first being the field work, which once analyzing the results it was possible to show that the product indices in the three phases (initial, growth and fattening) there were significant differences, indicating that the T2 (3 ml / L) obtained higher values than the rest with a final weight of 2397.42 g, weight gain of 2355.13 g and feed conversion of 1.63. In the same way, the European Efficiency Index (EEI) was evaluated, in which it was determined that all treatments including the control obtained acceptable values, however the best was T2 with a value of 293.61. The second part of the research was the measurement of intestinal pH on two occasions, resulting in T2 (3 ml / L) obtaining lower pH values compared to the other treatments, on day 21 of age in the duodenal portion. had a value of (pH: 5.97), while in the following portions (jejunum and ileum) there was no significant difference, on day 42 it was obtained in the portion of the jejunum (pH: 6.34) and ileum (pH: 6, 12). The cost / benefit was analyzed where a minimum margin of profit was achieved between the treatments, with the control and T1 (1 ml) being the one with the greatest gain.
