El experimento se realizó en el laboratorio CIPNA-CIDBAN y en las instalaciones de la Facultad de Zootecnia, ubicados en la Universidad Nacional Agraria de la Selva, Provincia Leoncio Prado, Región Huánuco-Perú; con el objetivo de determinar la capacidad antioxidante, in vitro del extracto etanólico del rizoma de Dracontium spruceanum Schott (EERDs), y su efecto inmunomodulador en pollos parrilleros Cobb 500, criados a alta densidad. Para determinar la capacidad antioxidante, se consideró 5 tratamientos, T1: 30, T2: 80, T3: 130, T4: 200 y T5: 250 µg/ml de EERDs; el análisis estadístico utilizado fue el diseño completamente al azar (DCA); todo los tratamientos muestran capacidad antioxidante frente al radical DPPH, obteniendo un IC50 de 164.37 µg/ml. Para determinar el efecto inmunomodulador del EERDs, se utilizó 90 pollos durante 35 días de edad, distribuidos en tres niveles...

The objective of the research was to evaluate the antioxidant capacity and effect of the ethanol extract from the Dracontium spruceanum rhizome (EERDs) on the blood, biochemical and productive parameters of chickens. To do so, ninety, male, Cobb 500 broiler chickens were used. Once the dehydrated extract was obtained, it was place in the drinking water at concentrations of 0.0, 0.35 and 0.70 mg/mL of EERDs. The birds were distributed into three treatments, five repetitions and each repetition had six chickens. The variance analysis was done with the statistical program InfoStat and the averages of the treatments were analyzed with the 5% Tukey test. The results showed that chickens that consumed drinking water with EERDs presented (p < 0.05) greater concentrations of hematocrit, hemoglobin and erythrocytes; meanwhile, the serum protein and the glucose did not change (p > 0.05). The...
