Comparison of Pregnancy Tests in Morkaraman-Awassi and Tuj sheeps with Roc Analysis

The aim of this study was to compare with praticability and accuracy ratio of Ultrasound and Progesterone tests, which are used for diagnosis of pregnancy at the artificial insemination programme used for ewes and was performed at the days of 18th, and Abdominal Ultrasound tests which is applied at the 90th at the ground circumstances. This study performed in 61, 2-5 years old, Red Karaman-Awasi-Tuj ewes. It was determined at the artificial insemination programme, being pregnant 21 (34.4) and not being pregnant 40 (65.6%) at the end of the study. Datas of three different diagnosis tests was carried out Chi-Square analysis and was established significantly (p<0.01) interval coherence thanks to real diagnostic. The best result with ROC analysis was obtained from Abdominal Ultrasound test, which was done in 90th days, taken into consideration area under curve with 1.00. At the end of the pregnancy, progesterone test which was done in 18th days, areas under curves were calculated 0.875 and 0.805 respectively. According to all analysis, the best result was Abdominal Ultrasound test, but ultrasound pregnancy test which was done in 18th days, was be able to applied for early diagnosis at the ground circumstances practically.
