Abstract
El trabajo de Investigación se realizó con el propósito de evaluar la sustitución parcial
del maíz por la harina de pituca (Colocasia esculenta) en la ración y su efecto sobre
los parámetros productivos de pollos parrilleros en la etapa de acabado en Yurimaguas-
2018. Los parámetros evaluados fueron: consumo de alimento, incremento de peso,
conversión alimenticia, índice de mortalidad y el mérito económico, en 144 pollos
machos de la línea Cobb 500, de veintiún días de edad, empleando el Diseño
Estadístico Completamente al Azar (DCA), con cuatro tratamientos y tres repeticiones,
y un grado de confiabilidad (P<0.05). Los tratamientos fueron: T0: 0.0%; T1:5%;
T2:10% y T3:15% niveles de harina de pituca que sustituira al maíz. Se obtuvo los
resultados: para el consumo acumulado de alimento: 631.89; 687.70; 644.44, 641.59
g en los tratamientos T0, T1, T2 y T3 respectivamente, observando diferencias
estadísticas significativas entre tratamientos (P < 0.05). Con respecto al incremento de
peso acumulado los valores encontrados fueron: T0: 2003.84, T1: 2026.71, T2: 2000 y
T3: 1995.32 g. Se encontró diferencias estadísticas significativas (P < 0.05) entre
tratamientos: Asimismo, en la conversión alimenticia acumulada se obtuvieron los
valores de: 0.30; 0.33, 0.23 y 0.31 para los tratamientos T0, T1, T2 y T3,
correspondientemente, no encontrándose diferencias estadísticas significativas entre
tratamientos (P < 0.05). En cuanto al índice de mortalidad, no se registró mortalidad
entre los tratamientos. El mayor mérito económico logrado fue en el T1, mostrando
una mejor rentabilidad con un valor de S/ 4.99.
The research work was carried out with the purpose of evaluating the partial substitution of maize for the pituca flour (Colocasia esculenta) in the ration and its effect on the productive parameters of broiler chickens in the finishing stage in Yurimaguas-2018. The parameters evaluated were: food consumption, weight gain, feed conversion, mortality index and economic merit, in 144 male chickens of the Cobb 500 line, of twenty-one days of age, using the Fully Random Statistical Design (DCA) , with four treatments and three repetitions, and a degree of reliability (P <0.05). The treatments were: T0: 0.0%; T1: 5%; T2: 10% and T3: 15% levels of pituca flour that will substitute corn. The results were obtained: for the cumulative consumption of food: 631.89; 687.70; 644.44, 641.59 g in the treatments T0, T1, T2 and T3 respectively, observing significant statistical differences between treatments (P <0.05). With respect to the accumulated weight increase, the values found were: T0: 2003.84, T1: 2026.71, T2: 2000 and T3: 1995.32 g. Significant statistical differences were found (P <0.05) between treatments: Likewise, in the cumulative feed conversion the values of: 0.30 were obtained; 0.33, 0.23 and 0.31 for the treatments T0, T1, T2 and T3, correspondingly, no significant statistical differences were found between treatments (P <0.05). Regarding the mortality rate, there was no mortality among the treatments. The greatest economic merit achieved was in the T1, showing a better profitability with a value of S / 4.99.
