Gender Identification in Emu (dromaius Novaehollandiae) - a Review
Distinct phenotypic sexual dimorphism servers as one of the key factors that can enable one to categorize the individual to a particular sex. However in case of ratite bird emu (Dromaius novaehollandiae) this phenotypic distinctness between males and females is less evident and careful observation of adult birds would help to identify the sexes. Other methods of sex identification such as the s...
متن کاملCirculatory changes associated with the closure of the ductus arteriosus in hatching emu (Dromaius novaehollandiae).
In developing avian embryos, the right and left ductus arteriosi (DA) allow for a shunt of systemic venous return away from the lungs to the body and chorioallantoic membrane (CAM). Unlike in mammals where the transition from placental respiration to lung respiration is instantaneous, in birds the transition from embryonic CAM respiration to lung respiration can take over 24h. To understand the...
متن کاملA re-evaluation of sperm ultrastructure in the emu, Dromaius novaehollandiae.
Existing reports on sperm structure in the emu do not adequately illustrate or describe all the salient ultrastructural features necessary for a meaningful comparison of normal and abnormal sperm in this species. As sperm morphology forms an important parameter in determining semen quality, and in view of the proposed role of artificial insemination in the farming of ratites, this article re-ev...
متن کاملCOMPARATIVE MICROANATOMICAL FEATURES OF THE RENAL CORTEX IN EMU (Dromaius novaehollandiae) AND DUCK (Anas platyrhynchos)
The present study was conducted on each of the three adult birds of Emu and Duck procured from the farms located in and around Gannavaram. The renal parenchyma of Emu and Duck was divided into large cortical lobules and smaller medullary lobules/cones. The renal cortex of both the birds showed a labyrinth of tubules and renal corpuscles. Small loopless cortical (reptilian type) nephrons and lar...
متن کاملAn immunohistochemical study of ovarian innervation in the emu (Dromaius novaehollandiae).
The present study investigated the distribution of nerves in the ovary of the emu. The neuronal markers, protein gene product 9.5, neurofilament protein and neuron specific enolase demonstrated the constituents of the extrinsic and intrinsic ovarian neural systems. The extrinsic neural system was composed of ganglia in the ovarian stalk, as well as nerve bundles, which were distributed througho...
