Abstract
The present study aimed to evaluate the effect of propolis use on hematological and serum biochemical parameters in Blue-fronted Amazons (Amazona aestiva). For this, 12 adult birds were distributed randomly into individual cages, divided into treatments with different propolis levels (A = 0.0%; B = 0.5%; and C = 1.0%), in 3 distinct phases (I, II, and III), with 15-d duration for phases I and III and 30 d for phase II, totaling 60 d. In phases I and III, all birds received treatment A ration, and in phase II received A, B, or C (4 birds per treatment). At the end of each phase, blood was collected for biochemical and hematological evaluations. The variables were analyzed by ANOVA (P < 0.05). Results suggest that 0.5% propolis reduced lactate dehydrogenase levels, whereas treatment B augmented hemoglobin concentrations and eosinophil count. It is concluded that 0.5% propolis improves levels of lactate dehydrogenase, hemoglobin, and eosinophils.
