1. Non- invasive - Ultrasound is free of radiation and radioactive damage.

2. Real-time imaging - Ultrasound allows real-time observation of internal organs and tissues, enabling real-time monitoring of animal and fetal health.

3. No side effects - Ultrasound does not require drugs or anesthesia, which makes it particularly suitable for a wide range of animals. In addition, unlike other imaging techniques, it does not cause side effects. In some cases, however, a mild sedative may be required to help the animal lie still.

4. Timeliness - Compared to other techniques, ultrasound provides accurate imaging more quickly.

5. Ease of Access - Ultrasound is also easier to obtain. Ultrasound can obtain cross-sectional images in various orientations, which are close to anatomically real structures and can acquire a wealth of information.
