Effect of copaiba essential oil on broiler chickens' performance

The effects of copaiba essential oil on growth performance and yield of slaughtered broilers were evaluated. Four hundred and fifty broiler chicks were distributed in a completely randomized design, with five treatments, and six replicates of 15 broiler chicks. Treatments comprised Control (commerci...

Four hundred and fifty broiler chicks were distributed in a completely randomized design, with five treatments, and six replicates of 15 broiler chicks. Treatments comprised Control (commercial promoter) and four levels of copaiba essential oil, or rather, 0.15 (0.15EO); 0.30 (0.30EO); 0.45 (0.45EO) and 0.60 mL (0.60EO) kg-1feed. The 21-day-old broilers fed on growth promoter had a greater body weight than that of birds fed on treatments with inclusion 0.30, 0.45 and 0.60 mL of essential oil (p < 0.05). Aged 40 days, only the broilers fed on treatment with high level of inclusion of essential oil showed lower body weight when compared with those fed on treatment with growth promoter (p < 0.05). Feed intake, feed conversion, viability of broilers, carcass yield, commercial cuts and weight of the internal organs were not affected by treatments (p > 0.05). The efficiency of productive index decreases in proportion to the increase of copaiba essential oil inclusion level. Copaiba essential oil may be included in the diet up to 0.15 mL kg-1level without affecting the performance of broiler chickens. Um estudo foi conduzido para avaliar os efeitos do óleo essencial de copaíba sobre o desempenho e rendimento de abate de frangos de corte. Foram utilizados 450 pintos, distribuídos num delineamento inteiramente casualizado com 5 tratamentos e 6 repetições de 15 aves. Os tratamentos consistiram em Controle (promotor comercial) e quatro níveis de óleo essencial de copaíba sendo estes 0,15 (0,15EO); 0,30 (0,30EO); 0,45 (0,45EO) e 0,60 mL (0,60EO) kg-1 de ração. Aos 21 dias de idade, as aves do tratamento com promotor apresentaram peso corporal superior ao das aves que receberam os tratamentos com 0,30; 0,45 e 0,60 mL de inclusão de óleo essencial (p < 0,05). Aos 40 dias de idade apenas as aves que receberam o tratamento com maior nível de inclusão de óleo essencial apresentaram menor peso corporal em relação ao tratamento com promotor de crescimento. O consumo de ração, a conversão alimentar e a viabilidade das aves, assim como o rendimento de carcaça, cortes comerciais e peso dos órgãos internos não foram afetados pelos tratamentos (p > 0.05). Conclui-se que o óleo essencial de copaíba pode ser usado na ração até o nível de 0,15 mL kg-1 sem afetar o desempenho das aves. 2015-03-30T12:49:31Z 2015-03-30T12:49:31Z 2013-06 Artigo de Periódico AGUILAR, Cesar Augusto Lopez et al.
