Anticoccidial effects of Camellia sinensis (green tea) extract and its effect on blood chemistry of broiler chickens

C urrent experiment was executed to evaluate anticoccidial effects Camellia sinensis extract in broiler chickens. Broiler chicks (n=72) were divided into six equal groups. Group A received Camellia sinensis extract (CSE) @ 40 gm/kg of basal diet), Group B received CSE @ 50gm/kg of basal diet), Group C received CSE 60gm /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 was also collected. Camellia sinensis extract reduced Eimeria infection in expressions of reduced mortality (%),OPG, lesion and oocyst scores and improved FCR in broiler chickens (P>0.05). The green tea extract also improved hematology and serum chemistry of infected chickens. It was concluded from experiment that Camellia sinensis can serve as alternative candidate against poultry coccidiosis
