Effect of adding white tea powder (Camellia sinensis) to the Japanese quail (Coturnix coturnix japonica) birds rations in some traits of blood biochemical and liver enzymes

The experiment was conducted in the animal production field that is following to College of Agriculture, University of Tikrit, and for 8 weeks to study the effect of adding white tea powder (Camellia sinensis) to the Japanese quail (Coturnix coturnix japonica) birds rations in some traits of blood biochemical and liver enzymes, the 45 females were used with age of 24 weeks. Birds were randomly distributed to three treatments, each treatment consists of five cages, where in each cage was placed 3 female quail and treatments were as follows: The first treatment: (T1) standard ration without addition, the second treatment: (T2) standard ration added 1 g white tea powder / kg feed, and the third treatment: (T3) standard ration added 1.5 g white tea powder / kg feed. The blood samples were collected after slaughtering the birds in tubes that did not contain the anticoagulant. The blood plasma was separated by a centrifuge at 3000 cycles for 15 minutes. The serums was kept in clean tubes at -20 °C. The experiment included the study of the following traits: Uric Acid, Glucose, Total Protein, Albumin, Globulin, Cholesterol, Triglycerides, High-Density Lipoprotein(HDL), Low Density Lipoproteins(LDL), Glutamic-Oxaloacetic Transminase Enzyme (GOT), Transminase Glutamic-Pyruvic Enzyme (GPT) and Alkalin-Phosphatase Enzyme (ALP). The results showed significant improvement (p <0.05) in white tea treatments in total protein concentration, albumin, globulin, high density lipoproteins and (ALP) compared to control treatment and significant decrease (p <0.05) in uric acid concentration, glucose, cholesterol, triglycerides, Low Density Lipoproteins, GOT and GPT. The current experiment suggests that the addition of white tea in the rations can lead to improvement of some parameters of biochemical blood and ALP enzyme.
