1. Clean out the excreta in cow's rectum.
2. Palpate by hand and preliminarily estimate the gestation state to determine the germinal tissue for B ultrasonic scanning.
3. Hold the probe, and insert it into the rectum with hand on the probe closely. Position your hand at the dorsal part between the rectum wall and the transducer.
4. Observe the internal structure on the screen. Move the probe inside the rectum until the coupling section of uterine horn and uterine body is displayed.

Two effective methods for pregnancy diagnosis:

• Within 35 days: Rectal method is more precise.
• 35 to 70 days: Both rectal and abdominal methods are equally effective.
• After 70 days: Abdominal method is preferred for the larger womb.

Abdomen Check Steps:

1. Can be done while the ewe is standing, lying, or squatting. Place the probe on the middle abdomen (fur-free area).
2. Ensure the area is clean; use water to remove mud if necessary for accurate visualization.
