Use of transcutaneous ultrasonography to characterize ovarian status, size distribution, and hierarchical status of follicles in Japanese quail (Coturnix coturnix japonica)
چکیده انگلیسی

The present study was undertaken to evaluate the ovarian status of matured breeding female Japanese quail by means of B Mode portable ultrasound scanning. Active ovaries in various stages of hierarchical development and different morphological structure were observed. The large yellow follicles appeared as a cluster of dark circles with various intensity of hyperechoic concentric ring. Sonographically, these follicles were classified into F1, F2, and F3 measuring 16.20 ± 0.06 mm, 12.48 ± 0.09 mm, and 7.95 ± 0.16 mm, respectively. A comparative study on preslaughter and postslaughter ovarian follicular status revealed accuracy of follicles less than 10 mm, 10–15 mm, 15–18 mm, and greater than 18 mm as 26.31%, 78.9%, 93.75%, and 100%, respectively, with an overall accuracy of 71%. This is the first report on the application of transcutaneous ultrasonographic technique to monitor ovarian status on Japanese quail reporting that the ovarian follicular activity and morphological structure can be monitored nonintrusively throughout quail life which can used as model for reproductive and biomedical research.
