| description | This research was carried out in the experimental area of the Santa Inés Farm belonging to the Faculty of Agricultural Sciences of the Technical University of Machala-Ecuador, with the purpose of evaluating the effect of a diet without antibiotics, coccidiostats and synthetic amino acids, administered to sexed Cobb 500 chickens on the productive parameters: live weight, water and accumulated feed consumption, feed conversion, mortality, ante-mortem weight, carcass weight andcarcass yield percentage. A DCA was used, in which only one factor to manipulate was used, the balance, separating males from females, from a sample of 100 birds, applying one replicate per sex, resulting in 4 experimental units (cages), with 25 sample units (chickens) per replicate, the cages were distributed with a number 1 and 4 (females), 2 and 3 (males), whose data were processed weekly. For the statistical analysis, the Statgraphics Centurión XV.I.® program was used, applying an ANOVA and to establish the differences between means, the Bonferroni multiple comparison procedure was used with a 95.0% confidence level. The results show that the males from the 2nd week onwards present the best weights, as well as the best carcass weight, while in the percentage of carcass yield and drinking water consumption, the females stand out, especially in the last days of the experiment. Showing a marked effect in some variables, when the sexes were subjected to a special diet. |

La presente investigación se desarrolló en el área experimental de la Granja Santa Inés perteneciente a la Facultad de Ciencias Agropecuarias de la Universidad Técnica de Machala-Ecuador, con la finalidad de evaluar el efecto de una dieta sin antibióticos, coccidiostatos y aminoácidos sintéticos, administrada a pollos Cobb 500 sexados sobre los parámetros productivos: Peso vivo, consumo de agua y alimento acumulado, conversión alimenticia, mortalidad, peso ante mortem, peso de la canal y porcentaje de rendimiento de la canal. Se empleó un DCA, en el cual se utilizó un único factor a manipular, el balanceado, separando los machos de las hembras, de una muestra de 100 aves, aplicando una réplica por sexo, dando como resultado 4 unidades experimentales (jaulas), con 25 unidades muestrales (pollos) por replica, las jaulas fueron distribuidas con un número 1 y 4 (hembras), 2 y 3 (machos), cuyos datos se procesaron semanalmente. Para el análisis estadístico, se empleó el programa Statgraphics Centurión XV.I.®, aplicando un ANOVA y para establecer las diferencias entre las medias se usó el procedimiento de comparación múltiple de Bonferroni con un nivel del 95,0% de confianza. Los resultados muestran que los machos a partir de la 2da semana presentan los mejores pesos, así como el mejor peso de la canal, mientras que en el porcentaje de rendimiento de la canal y consumo de agua de bebida destacan las hembras sobre todo en los últimos días del experimento. Demostrando un efecto marcado en algunas variables, al someter a los sexos a una dieta especial.
