What are the benefits of artificial insemination of dairy cows?

After taking bull semen with instruments, quality inspection, dilution, preservation and other appropriate treatments, the semen is transported to the uterus of estrus cows with instruments to make them pregnant. This method is called artificial insemination (AI) in reproduction. Artificial insemination is a major innovation in livestock breeding technology, and it is the most popular in cattle production. Artificial insemination of dairy cows mainly has the following advantages:

(1) Artificial insemination can give full play to the breeding value of excellent bulls. During natural mating, a bull can only breed dozens of cows a year, but if frozen semen is combined with artificial insemination, an excellent bull can breed thousands of cows a year, even reaching more than 654.38+100000, which greatly improves the reproductive efficiency of bulls and effectively promotes the promotion of excellent individuals and the speed of variety improvement.

(2) Artificial insemination can effectively prevent the spread of diseases. Because cows and males don't mate directly, it can prevent the spread of diseases such as reproductive system infectious diseases.

(3) Artificial insemination enlarges the utilization ratio of time and area. The service life of superior bulls is not limited by the service life, and the preservation and utilization of frozen semen not only overcomes the timeliness, but also facilitates communication between different regions.

(4) Artificial insemination technology is also a supporting measure for other reproductive technologies. For example, artificial insemination is an essential technology in the popularization and application of bovine embryo transfer and estrus synchronization.
