The B-ultrasound pregnancy tester for pigs can generally determine whether the sow is pregnant around 19-21 days after mating, estimate the number of fetuses around 22 days, and detect stillbirths around 40 days. When using a pig B-ultrasound machine to check if a sow is pregnant, some users may not be able to locate the probe, the image may not be visible, the pregnancy may not be analyzed based on the image, and the number of days of pregnancy may not be determined. Below is a technical explanation from Boxianglai on how to view animal B-ultrasound images?

The B-ultrasound image of the empty pregnant sow shows that the uterine angle is located on the left, right, and anterior lower part of the bladder, and the bladder cavity is a regular liquid dark area with no echo. The wall of the empty pregnant uterine angle has weak reflection to ultrasound, and its cross-sectional ultrasound image shows various irregular circular weak reflection areas. No liquid dark area is seen in the curved strong echo area above the uterine area, indicating that there is no gestational sac in this uterine angle.

The characteristics of pregnancy images of sows at 24 days of gestation: The gestational sac in the uterus of sows is composed of multiple irregular circular or elliptical dark areas with a diameter of 2-3 cm, smooth edges, and some embryonic spots can be detected, presenting as elliptical hypoechoic light clusters or spots. Above the strong echoic bright line is the uterine area.

On the 26th day of pregnancy, multiple irregularly shaped gestational sacs were detected in the uterus of a pregnant sow. Two adjacent gestational sacs and their fetal body reflections were displayed in the uterine area, and the fetal heartbeat could also be observed through imaging

On the 30th day of pregnancy, an enlarged gestational sac was detected in the dark area of the uterus, and the fetal bones showed strong echoes

Attention: In early pregnancy, the embryo is very small and should be scanned carefully and slowly to detect it. Do not slide the probe on the skin and scan quickly. When the bladder of a pig is filled with urine and swells, blocking the uterus and making it impossible to scan or only partially explore the uterus, detection should be carried out after the pig has emptied its urine
