RESUMO
In this study, the foot and hind limb bones of pigeons and quails were measured morphometrically. Additionally, microscopic classifications of the muscles affecting the foot and digit joints were made. For the macroscopic inspection, 40 birds were used, including 20 adult quails (10 males, 10 females) and 20 adult pigeons (10 males, 10 females). Diethyl ether was inhaled to anaesthetize the animals. The poultry animals were put under anaesthesia, and radiographic pictures of their left feet were obtained individually. DAP measurements were performed separately from the images taken with the Image J program. Then, they were euthanized by cervical dislocation under diethyl ether anaesthesia. The right legs of the euthanized animals were preserved in a 10% neutral formalin solution for histology procedures just after the legs were dissected from the trunk. Morphometric measurements of bone lengths were made in accordance with the measurement points specified by von den Driesch. After fixation for histological examination, routine tissue follow-up was performed and the tissues were embedded in paraffin. The presence of SO-type I, FG-type IIb and FOG-type IIa in 4-5 µ sections taken from paraffin blocks was demonstrated using the indirect streptavidin-biotin-complex method from immunohistochemical methods. The result of our study was statistically evaluated at p < 0.05 and p < 0.001 levels. The length of the hallux, the articulation point to the TMT and the fibre arrangements in the two flexor group muscles showed that the hind limbs and feet of the pigeons had a more favourable anatomical and histological structure for the perching movement.
