After years of practical exploration, this technology has become more and more mature, gradually replacing the application of synchronized estrus in practice, and has been recognized by the majority of dairy farming professionals. Synchronized ovulation technology is easy to use and can handle a large number of cattle at the same time. There is no need to observe estrus, and it can be bred at a fixed time. It can not only achieve early breeding and shorten the interval between births, but also is a good way to deal with anestrus and invisible estrus caused by ovarian diseases.

The application of cattle B-ultrasound diagnosis technology in dairy cattle breeding is often used in combination with synchronized ovulation technology. In order to shorten the interval between foetuses and increase the economic benefits of the ranch, this requires breeding workers to be able to find empty cows in advance and treat them symptomatically as soon as possible.

The application of cattle B-ultrasound just solves this problem, because cattle B-ultrasound can confirm whether the cow is pregnant 30 days after mating, which is much earlier than the diagnosis of rectal pregnancy. In this way, empty cows can be found in advance, and the cows can be synchronized early, which greatly shortens the interval between foetuses.

The application of gonadotropin-releasing hormone for synchronized ovulation and timed insemination technology, and the injection of gonadotropin into female animals can promote their superovulation. Screening most cows with long lactation days after delivery and injecting gonadotropin at the same time can promote their synchronous estrus. This technology is now widely used in large-scale ranches. This can greatly increase the participation rate of cattle, shorten the number of days of empty feeding, and promote the healthy development of ranches.

Today, as dairy cow reproductive diseases become more and more complicated, the previous rectal examination technology can no longer fully meet the needs of production. The application of ultrasonic diagnostic technology in dairy cow reproductive technology is the trend and mainstream of future development. It can guide the animal breeding industry to develop faster, healthier and more stable in practice and theory.
