EFFECT OF BROILER BREEDER MALE DOSING WITH DIFFERENT LEVELS OF WHITE TEA POWDER CAMELLIA SINENSIS AND URTICA DIOICA LEAVES ON SOME BIOCHEMICAL AND HISTOLOGICAL TRAITS OF LIVER.

The importance of research to study the effect of some additives on roosters' diet. The current study aim came intending to know the effect of adding different levels of powder white tea and nettle leaves to roosters' broth in some blood and liver tissue biochemical traits. The experiment was conducted in the Department of animal production from the College of Agriculture at Al-Qasim Green University for 42 days (from 10 April to 22 May 2022) in order to study the dosage of adding different levels of white tea powder Camellia sinensis and Urticadioica leaves to broiler breeder male. In some biochemical traits of blood and liver tissue, twenty-one roosters - 45 weeks old were used randomly distributed into seven treatments; each treatment contained three replicates (in each replicate one rooster), and the treatments were as follows: Treatment 1 (T1): a standard diet without addition; Treatment 2 (T2): a standard diet added to it 100 mg of white tea powder/kg of feed; Treatment 3 (T3): a standard diet to which 150 mg of white tea powder was added/kg of feed; Treatment 4 (T4): a standard diet to which was added 200 mg of white tea powder/kg of feed; Treatment 5 (T5): a standard diet to which 100 mg of nettle leaf powder was added/kg of feed; Treatment 6 (T6): a standard diet to which was added 150 mg of nettle leaf powder/kg of feed; Teatment 7 (T7): a standard diet to which was added 200 mg of powdered nettle leaves/kg of feed. White tea and nettle leaves were added in a dosage form. After the end of the study period, blood samples were collected from the jugular vein of the roosters in tubes that did not contain anticoagulants. The blood plasma was separated by centrifugation at a speed of 3,000 cycles for 15 minutes. The serum was kept in clean tubes at a temperature of -20 0C. Jordanian origin diagnostic kits measured total protein and albumin (g/100 ml) by UV-spectrophotometers from German origin. As for the globulin concentration, it was calculated according to the equation: (total protein concentration - albumin concentration). Tissue cutting was performed in Al-Sadr Hospital in Najaf Governorate, and liver tissue sections were read in the tissue laboratory of Al-Hussein Hospital in Holy Karbala. The significant differences between the means were compared using Duncan's polynomial test and the ready-made statistical program SPSS was used to analyze the experimental data. The results showed a significant improvement (P < 0.05) in some treatments of white tea and nettle leaves in the concentration of total protein, albumin, and globulin compared to the control treatment (the first). The study showed the results of histological cutting to the integrity of the liver from the presence of cirrhosis or congestion in most of the experimental treatments, but the presence of effects in some treatments such as T4, T5, T6, T7 where it was observed that there are minor effects between the presence of simple inflammation or a little congestion, but there is no cirrhosis or wax in the liver. It is concluded from the current experience that adding white tea leaves and crushed nettle leaves to the diet can improve some biochemical parameters of the blood. Also, w concluded that there is no significant effect on liver tissue. [ABSTRACT FROM AUTHOR]
