Supplementation of copaiba or sucupira oils in broiler diets

Abstract

SUMMARY The aim of this study was to evaluate the effect of supplemental copaiba or sucupira oils on broiler performance and intestinal health. A total of 600 one-day old Cobb 500 male broilers were distributed in a completely randomized design with four treatments and six replicates with 25 broilers each. To increase the health challenge, the broilers were reared on reused litter. The treatments consisted of: control diet; diet with a performance enhancing antibiotic (avilamycin); diet with 2,000 mg/kg copaiba oil and a diet with 500 mg/kg sucupira oil. Data were submitted to analysis of variance and Tukey test (5%). The addition of sucupira oil at 500 mg/kg decreased broiler performance at 21, 33, and 40 days of age, whereas the addition of copaiba oil resulted in similar performance relative to the antibiotic. Dietary supplementation of copaiba or sucupira oils did not change the intestinal epithelium of broilers. The addition of sucupira oil negatively affected broiler performance. Copaiba oil can be used in broiler diets as a performance enhancer.
