Veterinary ultrasound pig test methods of operation:
Bailing: sows generally do not need to bail, as long as it stays quiet, if there are conditions in the restriction of the pen in the sows to detect more convenient, posture sideways, the best quiet standing, lying down, or feeding can be.
2. Probing site: in vitro probing is generally around the lower abdomen, the upper part of the udder in front of the rear ribs, starting from the top of the back of the last pair of mammary glands, with the enhancement of gestation, the probing site is gradually moved forward, and finally up to the back end of the rib cage. The hair of the pig is sparse, and it is not necessary to cut the hair when probing, but it is necessary to keep the probing site clean so as not to affect the clarity of the ultrasound image. When probing the body surface, the probe and the pig skin contact area must be coated with coupling agent. If it is a rectal examination, there is no need for coupling agent.
3. Probing method: in vitro probing probe close to the abdominal wall, early pregnancy examination, the probe toward the anterior border of the pubic bone, the pelvic cavity inlet direction, or into a 45-degree angle diagonal to the opposite side of the upper, the probe is close to the skin, before and after, and up and down the fixed-point fan sweep, the action should be slow. The embryo is very small in the early stages of pregnancy, so it should be detected by careful and slow sweeping, do not slide the probe on the skin and scan quickly. (Probing techniques can be used flexibly according to the actual situation, has been able to detect the uterus inside the situation prevail, when the pig bladder full of urine distension, blocking the uterus, resulting in the inability to sweep to the uterus or only part of the uterus can be detected should be waiting for the pig to finish urinating after the exploration.
Analysis of practical application in pig farms
1, the first time to detect whether the pregnancy (the first estrus: 19-21 days) at this time to detect the presence or absence of pregnancy, for the farmers is the most cost-effective, and if the empty pregnancy can be re-matched in a timely manner, which greatly shortens the ineffective rearing time.
2, about 30 days after breeding to estimate the number of embryos as a large-scale farms, this is a must pay attention to the indicators. Early estimation of the number of embryos is conducive to the adjustment of nutritional formulas in the diet of pregnant sows as well as the amount of feeding. When the number of embryos and nutrition and diet can not keep up, it is easy to cause abortion or weak fetus; and when the number of embryos and nutrition and diet is too small, it is easy to cause the embryo individual development is too large, causing difficult birth.
3, 65 days after breeding can be detected with or without stillbirth as a farmer, the most afraid of is the emergence of stillbirth, early detection of stillbirth can be avoided not small economic losses. If there are stillbirths, you can do something about it according to the situation.
4, two, three times can not match the check whether there is uterine inflammation, ovarian cysts and other reproductive disorders ovarian cysts: commonly known as pig infertility, is currently plagued by one of the serious problems of the farmers, the main symptom is repeatedly with the infertility, the sows are obvious symptoms of estrus, the time of the estrus is more regular, but just can not match.
5, the mid-term can be detected with or without embryo absorption, is also one of the problems plaguing farmers the main symptoms: after breeding no longer have estrus performance two months or so when the stomach is a little big to the delivery period a little milk, but after the delivery period is not the performance of the litter.
