İvesi Irkı Koyunlarda Gebelik Muayenesi Amacıyla Dorsal Transrektal ve Transabdominal Yolla Yapılan Ultrasonografik Muayenenin Etkinliği

In this study, in a private operation where intensive Awassi breed sheep are raised; the results of the real-time ultrasonographic examination performed by the transabdominal method with a standing dorsal and supine posion and ventral transrectal examination for pregnancy examination were evaluated.The materials of the study consisted of at least one birth, 2-4 years old, 50 Awassi breed sheep randomly selected from the flock with the ram participation between 1 April and 1 May. Ultrasonographic examinations of the sheep were performed on June 1 and no changes were made in the feed and water regime before the examinations. The examinations were carried out with a linear array probe at a frequency of 6 MHz. The dorsal transrectal and transabdominal examination was performed a standing dorsal, and the ventral transrectal examination was performed in the supine position. According to the results obtained, pregnancy was determined in 8 animals in transabdominal and supine transral transrectal examinations and 1 animal in standing dorsal transrectal examinations. Consequently, it was found that dorsal transrectal examination may give low reliability results depending on the applied frequency in advanced pregnant animals. However, the more practical and serial examination under field conditions can be made via transabdominal approach.
