Abstract
La presente investigación se realizó en el distrito La Esperanza, Provincia de Trujillo, Región La Libertad; con el objetivo de determinar el efecto de dos niveles de extracto de tuna (opuntia ficus) en el incremento de peso en pollos de engorde línea Cobb 500. Se utilizaron 90 pollos distribuidos en tres tratamientos, bajo un diseño completamente al azar. Los tratamientos fueron: T0: control, T1: extracto de tuna 50 ml/lt, y T2: extracto de tuna 100 ml/lt. Los parámetros evaluados fueron: peso final total (PF), incremento de peso total (IPT), consumo de alimento total (CA), índice de conversión alimenticia (ICA), porcentaje de mortalidad (PM), índice de eficiencia productiva (IEP) y relación beneficio/costo(B/C). Los resultados fueron evaluaron estadísticamente con ANVA y la prueba exacta de Fisher. T0 obtuvo menor IPT y PF (2,50 y 2,54 kg) en comparación de T1 (2,52 y 2,56 kg) y T2 (2,54 y 2,58 kg), (p>0,05). El CA, el mayor valor lo obtuvo T2 (4,59 kg) seguido de T1 (4,56 kg) y T0 (4,55 kg) (p>0,05); en el ICA no se calcularon diferencias estadísticas entre los valores 1,79; 1,78 y 1,77 (p>0,05) para T0, T1 y T2 respectivamente. Para el porcentaje de mortalidad T0 obtuvo el mayor valor con 3.33% sin diferenciarse estadísticamente con T1 y T2 (p>0,05); en el IEP se obtuvieron 4,84% y 6,28% para T1 y T2 respectivamente, más que T0. En la relación beneficio/costo de los tratamientos, se obtuvieron diferencias numéricas para T0, T1 y T2 con 1,12, 1,14 y 1,13 respectivamente, donde T1 obtuvo los mayores ingresos. Se concluye, que el tratamiento T1 obtuvo los mejores parámetros productivos numéricamente pero no se determinaron diferencias estadísticas entre tratamientos.
ABSTRACT This research was conducted at La Esperanza, Province of Trujillo, La Libertad region; in order to determine the effect of two levels of prickly pear extract (Opuntia ficus) in weight gain in broilers cobb 500 line 90 chickens divided into three treatments under a completely randomized design were used. The treatments were: T0: control, T1: prickly pear extract 50 ml / lt, and T2: prickly pear extract 100 ml / lt. The parameters evaluated were: total final weight (PF), increased total weight (IPT), total food consumption (CA), feed conversion ratio (ICA), mortality rate (PM), productive efficiency index (IEP) and benefit/ cost ratio (B/C). The results were statistically evaluated with ANOVA and Fisher's exact test. T0 obtained IPT and PF lower (2.50 and 2.54 kg) compared to T1 (2.52 and 2.56 kg) and T2 (2.54 and 2.58 kg) (p> 0.05). The CA, the highest value was obtained by T2 (4.59 kg) followed by T1 (4.56 kg) and T0 (4.55 kg) (p> 0.05); in the ICA no statistical differences between the values 1.79 were calculated; 1.78 and 1.77 (p> 0.05) for T0, T1 and T2 respectively. For the mortality rate T0 obtained the highest value 3.33% undifferentiated statistically T1 and T2 (p> 0.05); the IEP 4.84% and 6.28% respectively for T1 and T2, rather than T0 obtained. The cost / benefit ratio of treatments, numerical differences for T0, T1 and T2 with 1.12, 1.14 and 1.13 respectively, where T1 obtained higher revenues were obtained. It is concluded that the treatment T1 had the best production parameters numerically but not statistically significant differences between treatments were determined.
