Operation method of veterinary B-ultrasound in detecting pigs;
1. Baoding: Sows generally don't need Baoding, as long as they keep quiet. It is more convenient to detect sows in the limit bar if conditions permit. It is best to lie on your side, stand quietly, lie down or eat.
2. Exploration site: In vitro exploration is generally around the lower abdomen and the upper part of the breast before the posterior rib, starting from the upper part of the last pair of breasts, gradually moving forward with pregnancy, and finally reaching the rear end of the rib. Pigs' fur is scarce, so it is not necessary to cut their hair during exploration, but the exploration site should be kept clean, so as not to affect the clarity of B-ultrasound images. When probing the body surface, the contact between the probe and pigskin must be covered with lotus root mixture. In the case of rectal examination, no coupling agent is needed.
3. Exploration method: During in vitro exploration, the probe is close to the abdominal wall. During the first trimester, the probe is inclined to the front of pubic bone, pelvic entrance, or at a 45-degree angle with the upper side of the opposite side. The probe is close to the skin, and it scans in a fan-shaped way from front to back, up and down, with slow movement. The embryo in the first trimester is very small, so it should be scanned carefully and slowly. Do not slide the probe over the skin and scan quickly. (The method of exploration can be used flexibly according to the actual situation, and the situation in the uterus can be explored. When the pig bladder is filled with urine and expands, blocking the uterus, so that the uterus can not be cleaned or only part of the uterus can be detected, it should be tested after the pig urinates.
