Current experiment was accomplished to evaluate anticoccidial effects Camellia sinensis extract in broiler chickens. Broiler chicks (n=72) were divided into six equal groups. First three groups received Camellia sinensis extract (CSE) @ 40 gm/kg, 50 gm/kg and 60 gm/kg of basal diet till at the end of experiment (40 days). Group D was treated with reference drug Toltrazuril® (1ml/liter of water) with basal diet. Group E served as infected, non-treated control group. Group F served as normal control group which received only basal diet. Anticoccidial activity of Camellia sinensis extract was evaluated by various parameters such as feed conversion ratio, mortality rate, Oocysts per gram of feces (OPG), lesion, and oocyst score and organ weight. Data on hematological parameters and serum chemistry were also collected. Camellia sinensis extract reduced Eimeria infection in expressions of reduced mortality (%), OPG, lesion and oocyst scores and improved FCR in broiler chickens which were non-significantly different to Toltrazuril® (P>0.05). The green tea extract also improved hematology and serum chemistry of infected chickens which were significantly different to infected group (P<0.05). It was concluded from experiment that Camellia sinensis can serve as alternative candidate against poultry coccidiosis.
