Veterinary ultrasound scanner is a high-tech means of cross-sectional observation of living organisms without any damage or stimulation and has become a favorable assistant for veterinary diagnostic activities and a necessary monitoring instrument for scientific research such as in vivo egg collection and embryo transfer.

According to the characteristics of different tissues and organs of animals with different densities and different ultrasound propagation speeds, i.e., different acoustic impedance, so that it produces a certain frequency of ultrasound, the ultrasound will be shot into the animal's body, through the interface of different organs in the body and produce reflected echoes; reflected echoes of different sizes, so that the received echoes, wave detection, and digital scan conversion and other processing, the formation of standard video signals, on the monitor screen to display the cross-sectional images of organs.

The transducer (probe) emits high-frequency ultrasonic waves through the piezoelectric effect into the body tissue to produce echoes, and the echoes are received by the transducer into a high-frequency electrical signal and transmitted to the host, after the amplification process on the fluorescent screen to show the section of the site being probed sonogram.

a. Detecting pregnancy, fetus.

b. Detecting gestation week and pre-term, distance, girth, area, heart rate, and fetal weight of pigs, cattle, dogs, horses, cats, goats, camels, and sheep.

c. Detection of pig backfat thickness and eye muscle area.

d. Obstetric disease detection (including endometritis, uterine pus accumulation, ovarian cysts, etc.)

a. Digital acoustic beam formation technology makes the image clear and delicate with high resolution.

b. Ultra-large scale FPGA and multi-channel high-performance amplifier. The circuit structure of multi-channel integrated ultrasonic emission technology is simple and efficient, and the reliability has been effectively improved.

c. Advanced probe production technology. Multi-layer acoustic matching, wide frequency band, high sensitivity.

d. Variable frequency emission technology to improve the resolution of the image in the near, middle, and far fields.

e. Rich software functions to adapt to user needs.

f. The instrument has a built-in lithium-ion rechargeable battery, and the battery can work continuously for more than 2 hours when fully charged.

g. High-speed CMOS integrated circuits and low-voltage devices. Low energy consumption and temperature rise, high reliability.

h. With a real-time clock. The date and time can be displayed automatically.

i. Launch has a variety of combinations of focus options.

j. The body is lightweight and easy to use.

a. Monitoring of follicles and corpus luteum: mainly reported in large bovine and equine animals, mainly because large animals can grasp the ovaries in the rectum and clearly show all sections of the ovaries; in small and medium-sized animals, the ovaries are smaller and often obscured by other internal organs such as the intestinal canal, which is difficult to grasp under non-surgical conditions, so it is not easy to show the ovarian sections. In cattle and horses, the ovaries can be examined with a 5.0-7.5 MHz linear or convex array probe through the rectum or vaginal vault, and the follicles and corpus luteum can be observed with the ovaries in hand.

b. The sonograms of the uterus during estrus and other periods of the sexual cycle are different. The endocervical layer and the myocervical layer are demarcated during estrus, and there are more hypoechoic dark areas with uneven texture on the sonogram due to the thickening of the uterine wall and the increased water content in the uterus. In late estrus and interestrus, the uterine wall image is brighter and the endometrial folds are visible, but there is no fluid in the cavity.

c. Monitoring of postpartum uterine regeneration. The uterine horns of primiparous cattle are mostly completely regenerated at 40 d after parturition, and about 50 d for menstruating cattle, when the regeneration is nearly completed, the uterine muscle layer is bounded by other tissues, the endometrium is gradually thickened and the image becomes white. In dogs, it takes about 15 weeks to complete uterine regeneration.

d. Ultrasound is more sensitive to endometritis and uterine pus. In inflammation, the uterine cavity is blurred, and the cavity is distended with partial echogenicity and snowflakes; in pus accumulation, the uterine body is enlarged, the uterine wall is clear, and there are liquid dark areas in the uterine cavity.

e. Early pregnancy diagnosis. The most published articles, both research and production applications. Early pregnancy diagnosis is mainly based on the detection of the gestational sac, or gestational body. The gestational sac is a round liquid dark area in the uterus, and the gestational body is a strong echogenic cluster or spot in a round liquid dark area in the uterus.

f. Observation of embryonic development. The embryonic development can be judged by observing the changes in extra-fetal structure and intra-fetal structure.

g. Monitoring the fetus alive or dead. A fetal heartbeat can be detected by ultrasound to predict fetal death. Before the embryo dies, the heartbeat decreases significantly. The fetal movement disappears, the fetal sac is full of liquid dark area, the germ cannot be seen, the echogenicity in the uterus is disturbed, the fetal sac, the placenta, and the fetal structure cannot be distinguished, etc. all indicate the death of the embryo.

h. Identification of fetal sex. The position of the fetal genital nodes inabouthe surrounding structures can be accurately identified by ultrasound. The accuracy of identifying the sex of the fetus is 96% at 50-105 d after the mating of cattle.

i. The number of fetuses and the gestational age can be estimated. Ultrasound can also determine the size of the fetus with a high degree of accuracy and can predict the date of calving based on the size of the fetus. The diameter of the fetal sac can be used to roughly estimate the size of the fetal age, and the diameter of the chorionic vesicle and the diameter of the uterus is also used to determine fetal age.

j. Monitoring of male reproductive organs. A 7.5MHz or 5.0MHz probe was used to probe the testes and secondary gonads of male animals via the body surface to diagnose diseases of male reproductive organs. This is mainly to observe whether there is fluid and calcification in the tissues and to detect urethral stones, cysts in the secondary gonads, fluid, hypertrophy, atrophy, etc.

a. B ultrasound is used for regular pregnancy monitoring, and early identification of empty sows reduces feeding waste and increases economic benefits. The accuracy of diagnosing pregnancy through ultrasound for early pregnancy monitoring has increased by at least 9 percentage points, timely detection of infertile sows, and avoidance of "invalid feeding". At the same time, ultrasound monitoring can accurately grasp the number of pregnant sows early and play a role in ensuring balanced production. Ultrasound can also monitor abnormal ovarian function or disease, empty pregnancy, uterine disease, stillbirth abortion, boar's testes, gonads, etc. The function of these functions and profit can detect abnormalities in time and take corresponding measures, thus greatly improving the monitoring of herd health. level and improve production efficiency.

b. Determination of backfat thickness and calculation of eye muscle area of pigs. The B ultrasound can be used to accurately determine the backfat thickness of pigs and calculate the area of eye muscles in vivo without damage, which greatly improves the science and accuracy of breeding selection.

c. Pregnancy analysis of transgenic and cloned sheep. Pregnancy was examined in white goats and natural mating sheep of embryo transfer recipients after transgenic or cytosolic transfer using an ultrasound tomograph equipped with a 5 MHz rectal probe. The results showed that the accuracy of negative pregnancy diagnosis (B-ultrasound judgment of non-pregnant goats) was 100% for test goats from 28 to 102 d after embryo transfer, and the accuracy of positive (B-ultrasound judgment of pregnancy) and negative pregnancy diagnosis was 100% for naturally mated and cell nuclear transplant recipient goats, with some transgenic recipient goats showing false positives due to fetal development arrest or abortion.

d. Application of B-type ultrasound diagnostic technology in the industrialization of embryo transfer in Boer goats. Diagnostic ultrasound technology has been more frequently used in mammalian embryo engineering and genetic engineering research for pregnancy detection, pregnancy monitoring, and supernumerary ovulation.

a. The first detection of pregnancy (first estrus: 19-21 days). Detecting the presence or absence of pregnancy at this time is the most cost-effective for the breeder. If the empty pregnancy can be timely re-mated, thus greatly reduces the time of ineffective breeding.

b. Estimating the number of embryos around 30 days after breeding is an important indicator for large-scale farms. Early estimation of the number of embryos is beneficial to the nutritional formula and the adjustment of feeding amount in the gestation sow diet. When the number of embryos is high and the nutrition and diet cannot keep up, it is easy to cause abortion or a weak fetus; while when the number of embryos is low and the nutrition and diet are excessive, it is easy to cause the embryo to develop too big and cause difficult birth.

c. Early detection of stillbirths can prevent considerable financial losses. If there is a stillbirth, it can be handled according to the situation.
