Abstract
The study was carried out on twenty adult, healthy turkeys of both sexes (native, balady breed) from local farms in Giza, weighing about 4-5 kilograms of bodyweight for the anatomical study. For the pharmacological study Seventeen male native Black native breed turkeys weighing between 3.5 and 4 kg, were obtained 2 weeks before the start of the study. The blood supply and the venous drainage study were done by the ordinary routine methods of coloured latex neoprene injection. The specimens were treated by the ordinary routine method of preserving using formaline 10%, phenol 4% and glycerine 1% mixture before dissection. The arterial blood supply of the gastrointestinal tract is derived from branches of the descending aorta; the celiac, cranial mesenteric, caudal mesenteric and internal iliac arteries. The venous blood coming from the gastrointestinal tract is drained through the right and left hepatic portal veins, the cranial proventricular vein which empties into the cranial vena cava in addition to the internal iliac veins. The hepatic portal system is formed by the communication of the right and left hepatic portal veins. Bile and serum concentrations of doxycycline (DOX) in turkeys were compared after single intramuscular (IM), intravenous (IV) and oral administrations of 20 mg/kg body weight (b.w.). DOX concentrations were determined by a reverse phase high-performance liquid chromatography HPLC with UV detection at 347nm
