The role of B-ultrasound machines for cattle in cow breeding is becoming more and more important. The operation and use of B-ultrasound machines for cattle is more complicated than that for pigs and sheep. Based on many years of practical experience, Mr. Yang from boxianglai will give you a detailed introduction to the use methods:

Ultrasound detection methods for cattle

1. Selection of exploration sites: The uterus of a cow in early pregnancy is located before and after the entrance of the pelvic cavity. The best site for external exploration is the huge udder in front of the pubic bone, the rumen on the left, the intestinal loop on the right, and the thick muscle groups on the buttocks, which are far away from the uterus in early pregnancy. Therefore, the best exploration site can only be selected in the vagina or rectum that is closer to the uterus. In the middle and late pregnancy, when the uterus sags close to the abdominal wall, the lower abdominal wall can be explored.

2. Exploration method: The cow is restrained in a natural standing position on the cow bed or in a column pen, just like rectal palpation and rectal grasping and insemination. It can be operated by one person without special restraint. If necessary, an assistant will fix the tail next to it. Rectal exploration: First stimulate the cow's anus with a long cup rectal probe to induce the cow to defecate, then insert the probe into the anus and then slowly insert it into the deep part of the rectum. Type B instrument exploration uses a handheld rectal probe specially made for large animals, which is brought into the rectum close to the ovaries and uterus for scanning. When there is a lot of feces in the rectum, the feces should be discharged first so that the probe can closely contact the rectum wall. When the probe is stained with feces and affects the exploration, it should be removed and cleaned. In order to closely contact the intestinal wall and protect the probe, it is best to apply coupling agent.
