Effect of Ethanolic extract green tea (Camellia sinesis) on lipid profile, growth performance and some carcass characteristics of local female rabbits


The present study was carried out on (40) female local rabbits the average weight (2.800± 250gm) the rabbits were divided into two equal groups. The first group was a control group contain 20 rabbits which oral administration with distilled water only for two weeks . The second group treated with Ethanolic extract of green tea contain 20 rabbits with dose 150mg/kgbw for two weeks. The study was aimed to determined the effect of ethanolic extract green tea(Camellia sinesis)on some blood parameters level of Total cholesterol, Triglyceride, low density lipoprotein, High Density Lipoprotein, Very low Density Lipoprotein, the oral administration of green tea extract physiological and histological results the levels of total cholesterol and low density lipoprotein recorded a significant decrase (p≤ 0.05)when compared with control group. The levels of Triglyceride, High Density Lipoprotein and Very low Density Lipoprotein did not record significant increments in comparison with control group. The results presented that the body weights showed significant decrements (p<0.05) when compared with the control group. The weights of livers of treated group enlisted a significant decrement(p< 0.05) while the weight of kidneys did not record any significant changes as compared with the control group.The histopathological results showed presence of hepatic architecture which were obvious for hepatic cells around the central vein, dilation of hepatic sinusoids with proliferation of the endothelial cells which lining the sinusoids with vaculation of the hepatic cells and hyperplasia which were simple in the bilary ducts inside the hepatic tissue.The hepatic cells showed in some slides proliferation and had prominent and clear nuclei with cytoplasm and some hepatic cells presented had two nuclei; These changes were clear and positive when compared with the livers of the control group which appeared with normal tissue, whereas the hepatic cells arranged in radiated shape around the central vein.
