PUJADA ABAD, Hilario; VEGA-VILCA, Jaime; VELASQUEZ VERGARA, Carlomagno e PALACIOS-RODRIGUEZ, Betty. Levels of oregano (Origanum vulgare) in the diet and its influence on the productive performance of the broiler. Rev. investig. vet. Perú [online]. 2019, vol.30, n.3, pp.1077-1082. ISSN 1609-9117. http://dx.doi.org/10.15381/rivep.v30i3.16599.
The aim of this study was to determine the optimum level of oregano (Origanun vulgare) in the diet on the productive performance of broilers. A total of 120 1-day-old male chickens from the Cobb-500 line were randomly distributed in four treatments: 0, 0.5, 1.0 and 1.5% of dried and ground oregano in the diets. The final bodyweight, feed consumption and feed conversion were determined. Data was analysed by an analysis of variance through a completely randomized design and the Tukey test for the comparison of means. The polynomial regression and the derivative of a quadratic function were used to find the optimum level of oregano in the variables. The levels of oregano influenced bodyweight, feed consumption and feed conversion (p<0.05), denoting a quadratic effect. On average, the optimum level of oregano in the diet was 0.71%.
