Abstract: The study aimed to explore the effect of Green Tea by-product (GTB) on body weight and hematological parameters in calves of the Sylhet region in Bangladesh. Four replicate groups were attributed to each treatment with three calves per replicate. Each group numbered as T1, T2, T3 and T0. All groups were served with standard calf feed and fresh drinking water ad libitum. The control group T0 was fed with normal calves feed. Calves of group T1, T2 and T3 were maintained as treated group where group T1 was fed with 0.5% GTB with normal calves feed, group T2 was treated with 1% GTB and group T3 was treated with 2% of GTB, respectively. The body weight of calves was taken on day 0 of the experiment and again on day 30 and day 60 to compare with the initial body weight. Blood samples were collected at day 30 and day 60 of treatment for hematological and biochemical experiments. Body weight was significantly (p<0.05) increased in treated groups in comparison to the control group. GTB improved Hb concentration and Total Protein (TP) in treatment group T3 which was significantly (p<0.05) higher than that of control group T0. Effects of green tea by-product on RBC, WBC and glucose concentration results insignificant (p<0.05) enhance in the treated groups compared to the control group. Cholesterol, albumin and BUN concentration were decreased significantly (p<0.05) in treated groups (T1, T2 and T3). Our experimental data suggested that GTB has a momentous effect on body weight gain and physiological characteristics.
