Sheep Ultrasound Applications: Pregnancy testing, litter size, stillbirth, mummification, ovarian and uterine corpus luteum examinations, and other obstetric conditions.
Sheep Ultrasound Pregnancy Scanner Operation: In vitro examination: In early pregnancy, the test is performed on the udder-less areas on either side of the udder, directly in front of the udder, or between the udders. In mid-to-late pregnancy, the test can be performed on the right abdominal wall. While the udder-less areas do not require shearing, the lateral abdominal wall requires shearing. For intrarectal examination, after restraining the sheep, the examiner squats on the side of the sheep. After applying coupling gel locally or to the probe, the probe is placed firmly against the skin and scanned toward the pelvic inlet. Scanning can be performed from the front to the back of the udder, from the sides to the center, or from the center to the sides. Scan across the bladder to both sides. In early pregnancy, the gestational sac is small and the embryo is very small, so a slow and careful scan is required to detect it. The ewe usually takes a natural standing position with an assistant to support her.
The essential differences between B-ultrasound and A-ultrasound for sheep and the differences in their diagnostic procedures
For sheep pregnancy diagnosis, currently, sheep pregnancy is still diagnosed using a test ram to detect return of estrus between days 17-23 after mating, followed by a B-ultrasound diagnosis between days 28-45. B-ultrasound diagnosis for sheep is a physical diagnostic method that closely combines the physical properties of ultrasound with the acoustic characteristics of animal tissue structure. Currently, there are three main types of ultrasound diagnostic equipment: veterinary A-ultrasound, veterinary B-ultrasound, and veterinary Doppler ultrasound. Ultrasound diagnosis uses high-frequency sound waves to explore the animal’s uterus, amplifying the echoes and converting them into different signals for display.
Overall, veterinary A-ultrasound (sheep A-ultrasound) is a relatively inexpensive pregnancy diagnostic instrument, compact and portable. When a veterinary A-ultrasound detects a fluid-filled gestational sac in the uterus, the reflected sound waves are converted into an acoustic signal, typically a long, continuous tone. The accuracy of the test is high between 30 và 75 days after mating, but the false-negative rate increases after 75 Ngày.
Portable B-mode ultrasound (sheep ultrasound) is currently the most practical method for diagnosing pregnancy in ewes, particularly suitable for small-scale sheep farms and large-scale sheep operations. Doppler ultrasound utilizes the principle of the Doppler effect: relative motion between the ultrasound probe and the reflector causes a change in the echo frequency. This frequency shift is called a frequency shift. The degree of frequency shift is proportional to the relative velocity. When the two move in opposite directions, the frequency increases. This frequency difference (the frequency increase or decrease) can be detected by a detector, then amplified by low-frequency and high-power amplifiers to generate a Doppler signal from a speaker. While accuracy is high, the use of veterinary Doppler ultrasound requires the user to be able to distinguish the signal sounds at different stages of pregnancy to make an accurate diagnosis.
