چکیده
Background and aim: The aim of this study was to evaluate the time of osteogenesis and development pectoral girdle elements, wing and the ossification centers of these regions in post-heching time in common myna (Acridotheres tristis) with by using radiographic method. Materials and Methods: This descriptive study is done on myna after hatching. Fourteen myna (Acridotheres tristis) (۷ male and ۷ female) were reared in similar and standard conditions and radiography was done once every ۷ days to up ۹۰ days of wing bones. The assigned technique including processing the radiographic image with normal radiography film. Results: Differentiation of the wing in myna starts with the appearance of centers of undeveloped cartilages in humerus diaphysis, radius, and ulna at the end of the first week, and also carpal regions in the beginning of the third week. The growth sequence in humerus and radius, ulna and carpus, metacarpus, and digits are observed in various stages. Maximum growth is related to the maximum cartilaginous activity and ossification stages. Humerus keeps its growth connection constant with the length of the whole wing skeleton, although its growth scale lessens from the end of the third week. In adult specimens the formula of the digits of the fore limb is usually ۲:۲:۱ but it sometimes decreases to ۱:۲:۱. Conclusion: Based on this study, osteogenesis time in the wing bones of myna is ۷۰ days after hatching and some of the many contrasts that were mentioned about other birds can be evaluated and compared and also, there was no significant difference between male and female myna birds in relation to osteogenesis time.کلیدواژه ها
