BACKGROUND: Nutritional strategies targeting improvement of poultry performance and disease prevention are currently being developed and in this respect the dietary intake of spiced essential
oils and pre-biotics in raising broilers is receiving attention. OBJECTIVES: This study was conducted to compare the effects of diet containing ginger essential oils [GEO] and mannan- oligosaccharide [MOS] on growth performance, biochemical and hematological parameters, lymphoid organ weights and antibody response of broilers.
METHODS: A total of 375 day old male broiler chicks were randomly assigned to five treatments [five replicates per treatment] . Dietary treatments included basal diet as control, GEO-supplemented diets with inclusion levels of 50 [GEO1] , 100 [GEO2] or 200 [GEO3] mg/kg, and MOS supplemented diet with an inclusion level of 2 g/kg. CONCLUSIONS: The results showed that higher level of GEO [200 g/kg] similar to MOS supplementation, improved feed efficiency and immune response. This could meet consumers' demand for a safe feed additive
