The authors compared the results and tested the effectiveness of two methods of trans-vaginal echographic pregnancy diagnosis in 50 cows. The techniques (based on a 5 MHz convex transducer) provided an easy, safe, reliable and clean method to scan inner genital apparatus, either by simple vaginal or by recto-vaginal (or bimanual) approach. On field, the faster and more reliable findings by simple trans-vaginal method occurred between the 30th and 35th days of pregnancy. Rectal repletion and cranio-ventral uterine displacement out of the pelvic rim sometimes raised diagnostic difficulties or doubts. Therefore, negative diagnoses at simple trans-vaginal approach, often required the more reliable bimanual confirmation. For correct reproductive farm management, owing to physiologic embryonic losses, earlier diagnoses should be confirmed later.

Abstract
The authors compared the results and tested the effectiveness of two methods of trans-vaginal echographic pregnancy diagnosis in 50 cows. The techniques (based on a 5 MHz convex transducer) provided an easy, safe, reliable and clean method to scan inner genital apparatus, either by simple vaginal or by recto-vaginal (or bimanual) approach. On field, the faster and more reliable findings by simple trans-vaginal method occurred between the 30th and 35th days of pregnancy. Rectal repletion and cranio-ventral uterine displacement out of the pelvic rim sometimes raised diagnostic difficulties or doubts. Therefore, negative diagnoses at simple trans-vaginal approach, often required the more reliable bimanual confirmation. For correct reproductive farm management, owing to physiologic embryonic losses, earlier diagnoses should be confirmed later.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
