AbstractThe inclusion of oregano essential oil, alone or associated with salinomycin, was evaluated as an alternative to zinc bacitracin on the performance of broiler chickens. This study used 600 male Cobb 500® day-old chicks, raised 42 days in boxes with rice hulls, provided with tubular feeders and nipple drinkers. The experimental design was completely randomized with six diets and 10 replications with 10 birds per experimental unit. The diets were based on corn and soybean meal: positive control - antibiotic (zinc bacitracin) + 0.05% anticoccidial (salinomycin), negative control - basal diet (BD) without additives, DB + 0.05% of salinomycin and 0.03% of oregano essential oil (Orego-Stim®),
DB + 0.03% of oregano essential oil, DB + 0.05% of salinomycin and 0.05% of oregano essential oil, DB + 0.05% of oregano essential oil. There were no treatment effects on broiler performance until 21 days of age. In the other periods, at 35 and 42 days, the oregano essential oil at 0.03% combined with salinomycin presented similar effects as the positive
control, leading to the conclusion that 0.03% of oregano essential oil associated with the salinomycin can replace zinc bacitracin + salinomycin in broiler chicken diets.
