Abstract This study was conducted at the Poultry Researches Station/Department of Animal Resource/Directorate of Agricultural Researches/Ministry of Agriculture, during the period from 15/5/2018 to 21/7/2018 to study the effect of adding green tea powder in broiler diet on some physiological traits. In this study 300 (Ross 308) broilers at age of one day has been used, these birds has randomly distributed to 5 dietary treatments, each treatment has three replicated (20 birds/replicates) T1 control treatment without adding green tea powder while T2 was used (0.5%) of green tea powder, T3 used (1%) green tea powder, wherever T4 used (1.5%) of green tea powder and T5 used (2%) green tea powder. The birds had been fed with one diet during the experiment period and the diets content were calculated as (16), the results of this study showed: There was a high significant difference (P<0.01) in plasma total protein for adding treatment and reached the best average in T5 treatment and a minimum average in T1 treatment, observed a highly decreased (P<0.01) in plasma albumin levels for T4 treatment compared with other treatments, and there is a highly increased (P<0.01) in plasma globulin levels in T5and T4 treatment compared with T1, T2 and T3 treatments, there was a highly decreased (P<0.01) in cholesterol levels in T5 compared it with control and other treatments, in the same time the results showed a high significant decreased (P<0.01) in high density lipoprotein (HDL) for T5, T4 and T1 treatments compared to T3 and T2 treatments, and there was a high significant decreased (P<0.01) in low density lipoprotein (LDL) in T2, T3, T4 and T5 compared to control, there was a highly decreased (P<0.01) in very low lipoprotein (VLDL) levels in T5 compared with other treatments. For the triglyceride the results showed a high significant decreased (P<0.01) in blood plasma for T2, T3, T4 and T5 treatments compared with control treatment. This study recorded a highly decreased (P<0.01) in ALT level for T5 compared to T4, T3, T2 and T1, in the other hand there was a highly significance (P<0.01) in same trait for T3, T4 and T5 compared with T2, wherever the results showed a highly decreased (P<0.01) in AST level in T5 and T4 treatment compared with T1, T2 and T3 treatments.
