When using animal B-ultrasound machines, unclear images or misjudgments of B-ultrasound imaging can directly affect the daily management efficiency and production efficiency of pig farms. There are many reasons for misjudgment caused by operating animal B-ultrasound machines.

1、 Due to insufficient experience of the operator of the veterinary ultrasound machine

The animal B-ultrasound machine is a high-tech product that can only be operated smoothly with skilled experience, and the images produced can be easily judged. Therefore, the operator can only practice using B-ultrasound proficiently and master the characteristics of pregnancy B-ultrasound images to avoid misjudgment. If you cannot distinguish it from B-ultrasound images, you can consult our online experts, and we will provide careful training.

2、 Due to the performance and resolution of the veterinary ultrasound equipment itself

A high-performance ultrasound can provide clear images during pregnancy examinations, which can greatly improve accuracy and advance examination time. Some customers, when purchasing animal B-ultrasound machines, blindly think they are cheap, and are unaware that the performance of cheap B-ultrasound machines will affect the diagnosis results. Therefore, it is also recommended that users do not think they are cheap at the moment, and must purchase suitable B-ultrasound machines according to their own needs.

3、 Selection of detection time

Generally, different animals have different pregnancy stages, so the optimal diagnosis time will also vary. Studies have shown that the accuracy of using animal ultrasound to diagnose cow pregnancy reaches over 88.9% at 26-30 days after mating, 97.2% at 31-35 days, and 100% at 36 days or more. The monitoring of early pregnancy in sows can be carried out as early as 18 days after mating, and the accuracy of pregnancy monitoring between 20-30 days can reach 100%. Because B-ultrasound pregnancy is mainly determined by measuring the amniotic fluid inside the gestational sac of a pregnant sow. If the sow is pregnant, black spots (also known as dark areas) are displayed on the B-ultrasound image, and during this period, the proportion of amniotic fluid is the highest, and the formed black spots are also the best to identify and judge. Therefore, 20-30 days after sow mating is the best time to use ultrasound to test pregnancy!

4、 Accurate detection location

Finding the correct detection location will directly affect the detection effect. For example, when measuring cows, it is necessary to detect in the rectum, locate the uterine horn, and thoroughly explore. Properly increase the far-field gain parameter of the ultrasound and reduce the probe frequency. When testing pigs, it is necessary to explore the inner thigh and the outer abdominal wall of the nipple. The anatomical structures of different animals are different, and the frequency of ultrasound probes is also different, so the detected parts will also be different. If the detected parts are incorrect, the detection results will also be misjudged.

5、 Judgment of B-ultrasound images

According to the imaging principle of animal B-ultrasound, ultrasound encounters tissues with different structures and produces echoes of varying strength. However, as a single structure, liquid cannot produce echoes, and image feedback cannot be seen on the B-ultrasound machine, only black shadows (or black spots) can be seen. The blue color shown in the figure represents amniotic fluid. When ultrasound encounters the amniotic fluid, it does not reflect back, but only reflects back from the amniotic membrane. Therefore, the amniotic fluid shows a black spot on the ultrasound machine. Finding black spots means finding amniotic fluid, finding amniotic fluid means finding pregnant sows!

Therefore, to make good use of B-ultrasound, there are three important key factors: choosing the right position, using the right time, and looking at the right image! Continuous learning and accumulation of experience are necessary to become proficient. In addition, selecting high-quality veterinary ultrasound machines and finding good manufacturers to provide services is of utmost importance.
