This study was conducted to investigate the effects of in ovo administration of Eurycoma longifolia (Tongkat Ali) extract (TAE) on the survivability and pre hatch development of chicken embryo. A dose response study of 0.1 mg, 1 mg and 10 mg TAE/100g egg on embryo survivability during first 5 days of incubation showed that the 0.1 to 1mg exposures had no effect on embryo survivability, and the lethal dose to kill 50% (LD50) was at around 10 mg. The 0.1 mg exposure was found to be non-lethal to the developing embryo until 19th day of incubation and it also enhanced (p 1 mg/100 egg dose is lethal to developing chicken embryo, but the 0.1 mg TAE/100g egg exposure through in ovo injection can be a beneficial strategy to produce heavier and stronger day old chicks.Bang.
