| The study was carried out on 20 legs of ten adult clinically and healthy local and Tom were obtained from Mosul local market, were divided into three groups; the first and second groups were subjected to gross feature regarding to shape, position, relationship of tibiotarsal and fibula in both birds also the length and diameters of shank bone while third group study morphological of muscles, blood and nerve supply of leg. The purpose of this study, this part of the limb is popularly known as the (drum stick), the bird in lowering its body flexes knee and hock joints and this passively tenses these tendons of leg which clamp the digits about the perch, and that is the much longer than the femur and, in spite of importance study to parameters of leg are more economic to choose breed of fertilization depend on the measurement, the outcome of this investigation may served as a guide for successful study of domestic birds in Iraq. The results include in both birds, the leg is consist of tibia fuses with tarsal element, forming tibiotarsus and fiblula articulates with the femur that in contrast to mammals. In Tom the tibia has two cnemial crest in proximal extremity and the distal extremity has tendinal groove, but in local cock it has one cnemial crest of proximal extremity, and it has two tendinal groove in the distal extremity, while hock joint in the Tom and local cock is an intertarsal joint that unites the tibiotarsus with the tarsometatarsus but the stiff joint is similar to that seen in mammals. The mean length of tibiotarsal in Tom 17.99±0.44 cm and the mean length of tibiotarsal in local coke 11.74±0.31 cm, the mean diameter of tibiotarsal in Tom 3.02±0.0021 cm proximal part, 2.21±0.005 cm middle part, 1.94±0.0021 cm distal part, but the mean diameter of tibiotarsal in local coke 2.86±0.048 cm proximal part, 2.02±0.067 cm middle part, 1.51±0.0022 cm distal part. While the mean length of fibula in Tom 11.62±0.21 cm and the mean length of fibula in local coke 7.27±0.32 cm, the mean diameter of fibula in Tom 1.51±0.0021 cm proximal part, 0.81±0.0033 cm middle part, and 0.33±0.0043 cm the distal part,also the mean diameter of fibula in local coke 1.12±0.0025 cm proximal part, 0.51±0.007 cm middle part, and 0.23±0.0054 cm distal part. Tendon of muscles of shank bone in Tom generally ossification but remain that tendon in local cock. Also cranialis tibialis muscle has two head, femoral head is usually smaller than the tibial head and gastrocnimeus muscles is composed of three part into two birds which passes through the planter aspect of the tarsometatarsal joint, as soon as flexor digitorium muscle of both species can be grouped into three morphological level (superficial intermediate and deep), the muscles in turkey are very clearly distinguished are read deep color than it is rose color in local cock, blood, nerve supply and venous drainages of the shank bone in both birds by cranial tibial artery is passage with cranial tibial vein and common fibular nerve. | ||
