Abstract
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). The daily food consumption diminished (p 0.05) by the consumption of EERDs in the drinking water. It is concluded that the consumption of EERDs by broiler chickens from 1 to 35 days of age produces greater concentrations of the levels of red blood cells and diminishes the feed intake.
